Erysipelothrix rhusiopathiae is a nonsporulating, gram-positive, rod-shaped bacterium which was identified more than 100 years ago as the etiologic agent of swine erysipelas. Since then, it has been found to cause infection in several dozen species of mammals and other animals. Humans become infected through exposure to infected or contaminated animals or animal products. By far the most common type of human infection is a localized, self-limited cutaneous lesion, erysipeloid. Diffuse cutaneous and systemic infections occur rarely. Approximately 50 cases of endocarditis have been reported; all but one recent case have involved native valves. The organism may be isolated from biopsy or blood specimens on standard culture media. It is identified by morphology, lack of motility, and biochemical characteristics; identification may be confirmed by the mouse protection test. It is susceptible to penicillins, cephalosporins, erythromycin, and clindamycin, but it is often resistant to many other antibiotics, including vancomycin, a drug frequently used in empiric therapy for infections due to gram-positive bacteria.

Erysipelas was diagnosed in 2 succeeding caged layer flocks housed in the same building and was characterized clinically by sudden death. At necropsy, lesions comprised generalized congestion, hemorrhages in the skeletal muscles and visceral organs, and swelling of liver, spleen, and kidney with or without large irregular zones of necrosis. Focal to massive hepatic necrosis was seen histologically with minimal or no inflammatory reaction. Erysipelothrix rhusiopathiae was cultured from internal organs of affected birds in both outbreaks. Medication with penicillin in the feed controlled the mortality, but relapse occurred after cessation of medication. Two attendants who handled the dead birds in this building developed a painful localized infection of the fingers that later spread to the regional lymph node. The infection responded when antibiotic therapy for erysipeloid was initiated. (+info)Erysipeloid is a superficial bacterial infection of the skin, characterized by sharply demarcated, raised, and indurated (hardened) lesions that are red or purple in color. It is caused by the bacterium Erysipelothrix rhusiopathiae, which is commonly found in animals such as pigs, sheep, goats, and poultry.
The infection typically occurs through direct contact with contaminated animal products, such as meat, hides, or bones, or through wounds on the skin that come into contact with the bacteria. Erysipeloid is not typically transmitted from person to person.
Symptoms of erysipeloid include fever, chills, and swollen lymph nodes in addition to the characteristic skin lesions. The infection can be treated with antibiotics, such as penicillin or erythromycin, and typically resolves within a few days to a week. Prevention measures include wearing protective gloves when handling contaminated animal products and practicing good hygiene.
Erysipelothrix is a genus of Gram-positive, facultatively anaerobic bacteria that are commonly found in the environment, particularly in soil, water, and on the skin and mucous membranes of animals such as fish, birds, and swine. The bacteria are named after the disease they cause, erysipelas, which is a type of skin infection characterized by redness, swelling, pain, and fever.
Erysipelothrix species are small, non-sporeforming rods that can be difficult to visualize using standard Gram staining techniques. They are catalase-negative and oxidase-negative, and they can grow on a variety of media at temperatures ranging from 20°C to 45°C.
There are two species of Erysipelothrix that are clinically significant: Erysipelothrix rhusiopathiae and Erysipelothrix insidiosa. E. rhusiopathiae is the more common cause of human infections, which typically occur after exposure to contaminated animals or animal products. The bacteria can enter the body through cuts, abrasions, or other breaks in the skin, and can cause a variety of clinical manifestations, including cellulitis, septicemia, endocarditis, and arthritis.
Erysipelothrix infections are treated with antibiotics, such as penicillin or erythromycin. Prevention measures include wearing protective clothing and gloves when handling animals or animal products, practicing good hygiene, and seeking prompt medical attention if a wound becomes infected.
Erysipelothrix infections are caused by the bacterium Erysipelothrix rhusiopathiae, which can infect both humans and animals. This type of infection is most commonly seen in people who handle animals or animal products, such as farmers, veterinarians, and fish processing workers.
The two main types of Erysipelothrix infections are erysipeloid and septicemia. Erysipeloid is a localized skin infection that typically affects the hands and fingers, causing symptoms such as redness, swelling, pain, and warmth. Septicemia, on the other hand, is a more serious systemic infection that can affect multiple organs and cause symptoms such as fever, chills, muscle pain, and weakness.
Erysipelothrix infections are typically treated with antibiotics, such as penicillin or erythromycin. In severe cases of septicemia, hospitalization may be necessary to receive intravenous antibiotics and other supportive care. Prevention measures include wearing gloves and protective clothing when handling animals or animal products, practicing good hygiene, and seeking prompt medical attention if symptoms develop.
Swine Erysipelas is a bacterial disease in pigs, caused by the bacterium Erysipelothrix rhusiopathiae. The disease is characterized by sudden onset, high fever, lethargy, skin lesions (typically raised, red, and firm), and lameness. It can also cause endocarditis, which can lead to heart failure. The bacteria can be transmitted to humans through contact with infected animals or their meat, but human cases are rare and usually result in only mild symptoms. In pigs, the disease can be prevented through vaccination.
Penicillin G Procaine is a formulation of penicillin G, an antibiotic derived from the Penicillium fungus, combined with procaine, a local anesthetic. This combination is often used for its extended-release properties and is administered intramuscularly. It is primarily used to treat moderate infections caused by susceptible strains of streptococci and staphylococci.
The procaine component helps to reduce the pain at the injection site, while penicillin G provides the antibacterial action. The extended-release formulation allows for less frequent dosing compared to immediate-release penicillin G. However, its use has become less common due to the development of other antibiotics and routes of administration.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Penicillin G Benzathine is a type of antibiotic that is used to treat various bacterial infections. According to the International Journal of Antimicrobial Agents, Penicillin G Benzathine is a "water-soluble salt of penicillin G, which has a very high degree of stability and provides prolonged low-level serum concentrations after intramuscular injection."
It is often used to treat infections caused by streptococci and treponema pallidum, the bacterium that causes syphilis. Penicillin G Benzathine works by interfering with the ability of these bacteria to form a cell wall, which is essential for their survival. Without a functional cell wall, the bacteria are unable to grow and multiply, and are eventually destroyed by the body's immune system.
Penicillin G Benzathine is typically administered via intramuscular injection, and its prolonged release allows for less frequent dosing compared to other forms of penicillin. However, it may not be suitable for all patients, particularly those with a history of allergic reactions to penicillin or other antibiotics. As with any medication, Penicillin G Benzathine should only be used under the supervision of a healthcare provider.
