Resistance to levamisole resolved at the single-channel level. (1/22)

Levamisole is commonly used to treat nematode parasite infections but therapy is limited by resistance. The purpose of this study was to determine the mechanism of resistance to this selective nicotinic drug. Levamisole receptor channel currents in muscle patches from levamisole-sensitive and levamisole-resistant isolates of the parasitic nematode Oesophagostomum dentatum were compared. The number of channels present in patches of sensitive and resistant isolates was similar at 10 microM levamisole, but at 30 microM and 100 microM the resistant isolate contained fewer active patches, suggesting desensitization. Mean Po and open times were reduced in resistant isolates. The distribution of conductances of channels in the sensitive isolate revealed a heterogeneous receptor population and the presence of G25, G35, G40, and G45 subtypes. A G35 subtype was missing in the resistant isolate. Resistance to levamisole was produced by changes in the averaged properties of the levamisole receptor population, with some receptors from sensitive and resistant isolates having indistinguishable characteristics.  (+info)

Geographic distribution and epidemiology of Oesophagostomum bifurcum and hookworm infections in humans in Togo. (2/22)

In contrast to the rest of the world, infections with Oesophagostomum bifurcum are commonly found in humans in northern Togo and Ghana. In addition, infections with hookworm are endemic in this region. In the present study, a detailed map of the geographic distribution of O. bifurcum and hookworm infections in northern Togo was made. There were a number of foci with high prevalence of infection with O. bifurcum. All the villages examined were infected with hookworm, and the distribution was quite patchy. Women were infected with O. bifurcum more often than men, while infections with hookworm were more prevalent in men than in women. The prevalence and intensity of infection with both parasites were clearly age-dependent. We estimate that more than a 100,000 people in Togo are infected with O. bifurcum and more than 230,000 are infected with hookworm.  (+info)

Ultrasonographic detection and assessment of preclinical oesophagostomum bifurcum-induced colonic pathology. (3/22)

In northern Ghana and Togo, Oesophagostomum bifurcum infects an estimated 250,000 people, as determined by cultures of stool samples. The juvenile stages of the helminth develop within colonic wall nodules, causing Dapaong tumor or multinodular disease, at the rate of 1 case per week at Nalerigu Hospital in Ghana. Our aim was to discover whether suspected colonic-wall pathology is ultrasonographically visible in asymptomatic individuals living in the area where O. bifurcum is endemic. A total of 464 persons from 3 villages, ranging from highly infected to noninfected, were examined with ultrasonography. Anechogenic colonic lesions with posterior wall enhancement were observed in 71 (54.2%) of 131 and 57 (24.5%) of 233 persons from the villages of endemicity, and no lesions were seen in persons from the village outside the area of endemicity. We describe the lesions noted in this study as nodules caused by O. bifurcum, on the basis of their association at a population level with prevalence of larvae in stools, their expected ultrasonographic appearance and distribution (on the basis of our surgical experience with oesophagostomiasis), and the lack of a convincing differential diagnosis.  (+info)

Intraobserver and interobserver variation of ultrasound diagnosis of Oesophagostomum bifurcum colon lesions. (4/22)

Infection by the nematode Oesophagostomum bifurcum is focally distributed in Africa and causes a syndrome of abdominal pain, obstruction, or abdominal mass because of its predilection for invasion of colonic mucosa. To determine the reliability of ultrasound for the detection of colon pathology induced by this parasite, three studies to assess the intraobserver and interobserver variation of the technique were performed. In an area of northern Ghana endemic for O. bifurcum, 181 people from a low-prevalence village and 62 people from a high-prevalence village were examined twice by the same observer, and 111 people were independently examined by two observers in a moderately endemic village. The kappa statistics for the prevalence observations in the three studies were 0.82, 0.87, and 0.81, respectively, and kappa values for the intensity observations were 0.66, 0.63, and 0.71, respectively. The upper 95% confidence intervals of the average absolute difference in nodule size measurements in Study 1 and Study 3 were 3.6 and 4.5 mm, respectively. Therefore, ultrasound is useful in the diagnosis and management of O. bifurcum colon infection.  (+info)

Genetic substructuring within Oesophagostomum bifurcum (Nematoda) from human and non-human primates from Ghana based on random amplified polymorphic DNA analysis. (5/22)

Random amplified polymorphic DNA (RAPD) was used to study genetic variation within Oesophagostomum bifurcum in Ghana. Four different decamer primers were used for the amplification of DNA from individual O. bifurcum adults (n = 41) from humans and non-human primates (including the Mona monkey, Patas monkey and Olive baboon) from different geographic regions. Analysis of the amplicons from all 41 nematodes by high resolution, denaturing polyacrylamide gel electrophoresis defined a total of 326 informative RAPD bands. Cluster analysis of the RAPD data (based on pairwise comparison of banding profiles) showed that O. bifurcum from humans was genetically distinct from O. bifurcum from the Mona and Patas monkeys, and from the Olive baboon. These findings clearly demonstrate the existence of population genetic substructuring within O. bifurcum from different primate hosts in Ghana, and raise interesting questions about host specificity, epidemiology (e.g., zoonotic transmission), and ecology of the different genotypes of O. bifurcum.  (+info)

Oesophagostomum bifurcum in non-human primates is not a potential reservoir for human infection in Ghana. (6/22)

In northern Togo and Ghana, human infection with the parasitic nematode Oesophagostomum bifurcum is of major health importance. Elsewhere, oesophagostomiasis is considered a zoonotic infection, non-human primates being the natural host. We examined 349 faecal samples of the olive baboon, mona monkey and black and white colobus monkey from two geographically distinct areas in Ghana, outside the region endemic for O. bifurcum in humans. Using both microscopy and species-specific PCR, we found a high prevalence of O. bifurcum (75-99%) in olive baboons and mona monkeys. The majority of the test-positive faecal samples contained large numbers of larvae after copro-culture (>100). No O. bifurcum was detected in the faeces of the black and white colobus monkeys. Observational studies on the behaviour of the non-human primates, focusing on defecation, food consumption and the sharing of habitat with the local human population, indicated favourable conditions for zoonotic transmission. Given that no human infection with O. bifurcum has been reported from either study area, the present findings support the hypothesis that O. bifurcum from humans in the north of Ghana, and O. bifurcum from olive baboons and/or mona monkeys are distinct.  (+info)

Simultaneous detection and quantification of Ancylostoma duodenale, Necator americanus, and Oesophagostomum bifurcum in fecal samples using multiplex real-time PCR. (7/22)

A multiplex real-time PCR was developed and evaluated for the simultaneous detection of Ancylostoma duodenale, Necator americanus, and Oesophagostomum bifurcum in fecal samples. Using well-defined control samples (N = 150), known positive fecal samples (N = 50), and fecal samples from an area in Ghana where human infections with all 3 nematode species are endemic (N = 339), the method proved to be highly specific and sensitive. Cycle threshold (Ct) values, reflecting parasite-specific DNA load, showed significant correlation with the intensity of infection as measured by microscopy using Kato-Katz fecal smears or by species specific third-stage larval count after coproculture. The multiplex real-time PCR described combined with the simple fecal sample collection procedure and the potential for high throughput makes this approach a powerful diagnostic tool to study species-specific transmission patterns of human hookworm-like infections. Moreover, this procedure facilitates monitoring of intervention programs and allows species-specific detection of treatment failure following rounds of mass treatment.  (+info)

Nodular worm infection in wild chimpanzees in Western Uganda: a risk for human health? (8/22)

 (+info)

Oesophagostomum is a genus of parasitic roundworms that infect the gastrointestinal tract of various mammals, including primates and pigs. The adult worms are typically found in the large intestine, where they lay their eggs, which are passed in the feces and can contaminate the environment.

In humans, Oesophagostomum infection is also known as "nodular worm" or "whipworm of the large intestine." The larvae hatch from the eggs and penetrate the skin, causing a pruritic rash. They then migrate to the lungs, where they cause coughing and other respiratory symptoms before being swallowed and passing into the gastrointestinal tract.

Symptoms of Oesophagostomum infection in humans can include abdominal pain, diarrhea, anemia, and weight loss. In severe cases, the worms can cause intestinal obstruction or perforation. Treatment typically involves administration of anthelmintic drugs to kill the parasites.

Oesophagostomiasis is a parasitic infection caused by the nematode (roundworm) species Oesophagostomum. The infection primarily occurs in animals such as pigs, but can also affect humans, particularly in tropical and subtropical regions with poor sanitation.

In humans, oesophagostomiasis is usually contracted through the consumption of contaminated vegetables or water containing infective Oesophagostomum eggs. The larvae hatch in the small intestine, penetrate the intestinal wall, and migrate to the large intestine where they mature into adult worms.

The adult worms live in the large intestine, particularly the cecum and ascending colon, and produce eggs that are passed in the feces. Symptoms of oesophagostomiasis can include abdominal pain, diarrhea, nausea, vomiting, and weight loss. In severe cases, the infection can lead to intestinal obstruction or perforation.

Treatment for oesophagostomiasis typically involves the use of anthelmintic medications such as albendazole or mebendazole. Preventive measures include improving sanitation and hygiene, cooking vegetables thoroughly, and avoiding the consumption of untreated water.

Necatoriasis is a parasitic infection caused by the nematode (roundworm) Necator americanus, also known as the "New World hookworm." This condition is primarily found in areas with warm, moist climates and poor sanitation. The infection typically occurs when the larvae of the parasite penetrate the skin, usually through bare feet that come into contact with contaminated soil.

Once inside the human body, the larvae migrate to the lungs, where they mature and are coughed up and swallowed. They then reside in the small intestine, where they feed on blood and cause symptoms such as abdominal pain, diarrhea, anemia, and growth retardation in children. Necatoriasis is usually treated with anthelmintic medications like albendazole or mebendazole. Preventive measures include wearing shoes in areas where the parasite is common and improving sanitation to reduce the spread of contaminated soil.

Antinematodal agents are a type of medication used to treat infections caused by nematodes, which are also known as roundworms. These agents work by either killing the parasitic worms or preventing them from reproducing. Some examples of antinematodal agents include albendazole, ivermectin, and mebendazole. These medications are used to treat a variety of nematode infections, such as ascariasis, hookworm infection, and strongyloidiasis. It is important to note that the use of antinematodal agents should be under the guidance of a healthcare professional, as they can have side effects and may interact with other medications.

Nematode infections, also known as roundworm infections, are caused by various species of nematodes or roundworms. These parasitic worms can infect humans and animals, leading to a range of health problems depending on the specific type of nematode and the location of the infection within the body.

Common forms of nematode infections include:

1. Ascariasis: Caused by Ascaris lumbricoides, this infection occurs when people ingest the parasite's eggs through contaminated food or water. The larvae hatch in the small intestine, mature into adult worms, and can cause abdominal pain, nausea, vomiting, and diarrhea. In severe cases, the worms may obstruct the intestines or migrate to other organs, leading to potentially life-threatening complications.
2. Hookworm infections: These are caused by Ancylostoma duodenale and Necator americanus. The larvae penetrate the skin, usually through bare feet, and migrate to the small intestine, where they attach to the intestinal wall and feed on blood. Symptoms include abdominal pain, diarrhea, anemia, and protein loss.
3. Trichuriasis: Also known as whipworm infection, this is caused by Trichuris trichiura. The larvae hatch in the small intestine, mature into adult worms, and reside in the large intestine, causing abdominal pain, diarrhea, and rectal prolapse in severe cases.
4. Strongyloidiasis: Caused by Strongyloides stercoralis, this infection occurs when the larvae penetrate the skin, usually through contaminated soil, and migrate to the lungs and then the small intestine. Symptoms include abdominal pain, diarrhea, and skin rashes. In immunocompromised individuals, strongyloidiasis can lead to disseminated disease, which is potentially fatal.
5. Toxocariasis: This infection is caused by the roundworms Toxocara canis or Toxocara cati, found in dogs and cats, respectively. Humans become infected through ingestion of contaminated soil or undercooked meat. Symptoms include fever, cough, abdominal pain, and vision loss in severe cases.
6. Enterobiasis: Also known as pinworm infection, this is caused by Enterobius vermicularis. The larvae hatch in the small intestine, mature into adult worms, and reside in the large intestine, causing perianal itching and restlessness, especially at night.

Preventive measures include:

1. Proper hand hygiene: Wash hands with soap and water after using the toilet, changing diapers, handling pets or their feces, and before preparing or eating food.
2. Personal hygiene: Keep fingernails short and clean, avoid biting nails, and wear shoes in public areas, especially where soil may be contaminated with human or animal feces.
3. Food safety: Wash fruits and vegetables thoroughly, cook meat properly, and avoid consuming raw or undercooked meat, poultry, or fish.
4. Environmental cleanliness: Regularly clean surfaces that come into contact with food, such as countertops, cutting boards, and utensils. Dispose of trash properly and maintain a clean living environment.
5. Pet care: Keep pets healthy and regularly deworm them as recommended by a veterinarian. Pick up pet feces promptly to prevent contamination of the environment.
6. Public health measures: Implement public health interventions, such as regular waste disposal, sewage treatment, and vector control, to reduce the transmission of parasitic infections.

Necator americanus is a species of parasitic hookworm that primarily infects the human intestine. The medical definition of Necator americanus would be:

A nematode (roundworm) of the family Ancylostomatidae, which is one of the most common causes of human hookworm infection worldwide. The adult worms live in the small intestine and feed on blood, causing iron deficiency anemia and protein loss. Infection occurs through contact with contaminated soil, often through bare feet, and results in a skin infection called cutaneous larva migrans (creeping eruption). After penetrating the skin, the larvae migrate to the lungs, ascend the respiratory tract, are swallowed, and then mature into adults in the small intestine.

The life cycle of Necator americanus involves several developmental stages, including eggs, larvae, and adult worms. The eggs are passed in the feces of infected individuals and hatch in warm, moist soil. The larvae then mature and become infective, able to penetrate human skin upon contact.

Preventive measures include wearing shoes in areas with known hookworm infection, avoiding walking barefoot on contaminated soil, improving sanitation and hygiene practices, and treating infected individuals to break the transmission cycle. Treatment of hookworm infection typically involves administration of anthelmintic medications, such as albendazole or mebendazole, which kill the adult worms in the intestine.

Helminthiasis, in general, refers to the infection or infestation of humans and animals by helminths, which are parasitic worms. When referring to "Animal Helminthiasis," it specifically pertains to the condition where animals, including domestic pets and livestock, are infected by various helminth species. These parasitic worms can reside in different organs of the animal's body, leading to a wide range of clinical signs depending on the worm species and the location of the infestation.

Animal Helminthiasis can be caused by different types of helminths:

1. Nematodes (roundworms): These include species like Ascaris suum in pigs, Toxocara cati and Toxascaris leonina in cats, and Toxocara canis in dogs. They can cause gastrointestinal issues such as diarrhea, vomiting, and weight loss.
2. Cestodes (tapeworms): Examples include Taenia saginata in cattle, Echinococcus granulosus in sheep and goats, and Dipylidium caninum in dogs and cats. Tapeworm infestations may lead to gastrointestinal symptoms like diarrhea or constipation and may also cause vitamin deficiencies due to the worm's ability to absorb nutrients from the host animal's digestive system.
3. Trematodes (flukes): These include liver flukes such as Fasciola hepatica in sheep, goats, and cattle, and schistosomes that can affect various animals, including birds and mammals. Liver fluke infestations may cause liver damage, leading to symptoms like weight loss, decreased appetite, and jaundice. Schistosome infestations can lead to issues in multiple organs depending on the species involved.

Preventing and controlling Helminthiasis in animals is crucial for maintaining animal health and welfare, as well as ensuring food safety for humans who consume products from these animals. Regular deworming programs, good hygiene practices, proper pasture management, and monitoring for clinical signs are essential components of a comprehensive parasite control strategy.

Cercopithecinae is a subfamily of Old World monkeys that includes a diverse group of species, such as macaques, baboons, geladas, and langurs. These monkeys are characterized by their complex social structures, distinct coloration patterns, and adaptations to various habitats across Africa and Asia. Some notable features of Cercopithecinae include their tail-tufts, cheek pouches for food storage, and a variety of vocalizations used in communication.

Parasitic intestinal diseases are disorders caused by microscopic parasites that invade the gastrointestinal tract, specifically the small intestine. These parasites include protozoa (single-celled organisms) and helminths (parasitic worms). The most common protozoan parasites that cause intestinal disease are Giardia lamblia, Cryptosporidium parvum, and Entamoeba histolytica. Common helminthic parasites include roundworms (Ascaris lumbricoides), tapeworms (Taenia saginata and Taenia solium), hookworms (Ancylostoma duodenale and Necator americanus), and pinworms (Enterobius vermicularis).

Parasitic intestinal diseases can cause a variety of symptoms, including diarrhea, abdominal pain, bloating, nausea, vomiting, fatigue, and weight loss. The severity and duration of the symptoms depend on the type of parasite, the number of organisms present, and the immune status of the host.

Transmission of these parasites can occur through various routes, including contaminated food and water, person-to-person contact, and contact with contaminated soil or feces. Preventive measures include practicing good hygiene, washing hands thoroughly after using the toilet and before handling food, cooking food thoroughly, and avoiding consumption of raw or undercooked meat, poultry, or seafood.

Treatment of parasitic intestinal diseases typically involves the use of antiparasitic medications that target the specific parasite causing the infection. In some cases, supportive care such as fluid replacement and symptom management may also be necessary.

A "Parasite Egg Count" is a laboratory measurement used to estimate the number of parasitic eggs present in a fecal sample. It is commonly used in veterinary and human medicine to diagnose and monitor parasitic infections, such as those caused by roundworms, hookworms, tapeworms, and other intestinal helminths (parasitic worms).

The most common method for measuring parasite egg counts is the McMaster technique. This involves mixing a known volume of feces with a flotation solution, which causes the eggs to float to the top of the mixture. A small sample of this mixture is then placed on a special counting chamber and examined under a microscope. The number of eggs present in the sample is then multiplied by a dilution factor to estimate the total number of eggs per gram (EPG) of feces.

Parasite egg counts can provide valuable information about the severity of an infection, as well as the effectiveness of treatment. However, it is important to note that not all parasitic infections produce visible eggs in the feces, and some parasites may only shed eggs intermittently. Therefore, a negative egg count does not always rule out the presence of a parasitic infection.

Nematoda is a phylum of pseudocoelomate, unsegmented worms with a round or filiform body shape. They are commonly known as roundworms or threadworms. Nematodes are among the most diverse and numerous animals on earth, with estimates of over 1 million species, of which only about 25,000 have been described.

Nematodes are found in a wide range of habitats, including marine, freshwater, and terrestrial environments. Some nematode species are free-living, while others are parasitic, infecting a variety of hosts, including plants, animals, and humans. Parasitic nematodes can cause significant disease and economic losses in agriculture, livestock production, and human health.

The medical importance of nematodes lies primarily in their role as parasites that infect humans and animals. Some common examples of medically important nematodes include:

* Ascaris lumbricoides (human roundworm)
* Trichuris trichiura (whipworm)
* Ancylostoma duodenale and Necator americanus (hookworms)
* Enterobius vermicularis (pinworm or threadworm)
* Wuchereria bancrofti, Brugia malayi, and Loa loa (filarial nematodes that cause lymphatic filariasis, onchocerciasis, and loiasis, respectively)

Nematode infections can cause a range of clinical symptoms, depending on the species and the location of the parasite in the body. Common symptoms include gastrointestinal disturbances, anemia, skin rashes, and lymphatic swelling. In some cases, nematode infections can lead to serious complications or even death if left untreated.

Medical management of nematode infections typically involves the use of anthelmintic drugs, which are medications that kill or expel parasitic worms from the body. The choice of drug depends on the species of nematode and the severity of the infection. In some cases, preventive measures such as improved sanitation and hygiene can help reduce the risk of nematode infections.

Anthelmintics are a type of medication used to treat infections caused by parasitic worms, also known as helminths. These medications work by either stunting the growth of the worms, paralyzing them, or killing them outright, allowing the body to expel the worms through normal bodily functions. Anthelmintics are commonly used to treat infections caused by roundworms, tapeworms, flukeworms, and hookworms. Examples of anthelmintic drugs include albendazole, mebendazole, praziquantel, and ivermectin.
