An atypical case of respiratory actinobacillosis in a cow. (1/4)
A not pregnant 4-year-old Jersey cow was presented with the sudden appearance of respiratory noise, nasal discharge and moderate respiratory difficulty. Upon physical examination a snoring-like noise, extended head and neck position, exaggerated abdominal effort, bilateral nasal discharge and left prescapular lymph node enlargement were noted. Sub-occlusion of the initial portion of the respiratory tract was suspected. Radiographic and endoscopic examinations revealed a pedunculate mass on the dorsal aspect of the rhinopharynx, which was removed with endoscopically assisted electrosurgery. Histologic examination revealed a chronic pyogranulomatous inflammation with eosinophilic club-like bodies surrounding small colonies of rod-shaped bacteria. Results of histochemical staining were consistent with Actinobacillus-like bacteria and a diagnosis of respiratory actinobacillosis was reached. Surgery and antibiotic therapy were resolutive, as demonstated by an endoscopic check at the second month after surgery, even without the association of the traditional iodine cure, which is regarded as the treatment of choice for actinobacillosis.

(+info)Nonspecific toxicites in the mouse assay test for botulinum toxin. (3/4)
In inoculated pack experiments on Clostridium botulinum type E, unirradiated and 0.1-Mrad irradiated haddock fillets often gave nonspecific toxicities by the mouse assay test for botulinum toxin. Samples given 0.2-Mrad radiation failed to produce nonspecific reactions. Nonspecific deaths sometimes occurred within 24 hr after injection, although deaths between 24 and 48 hr were more common. The symptoms and the pattern of these deaths suggested a septicemia. Heart-blood cultured from mice showing nonspecific symptoms indicated an infectious process. Among 23 isolates from the blood, eight were identified as Proteus vulgaris, two P. morganii, one P. rettgeri, one Providence subgroup B, two Aerobacter aerogenes, one Actinobacillus, three enterococci, one Alcaligenes marshalli, and four Erysipelothrix insidiosa. The E. insidiosa, Aerobacter, Providence group, and most of the Proteus isolates were infectious for mice when injected by the intraperitoneal route. But the enterococci, Alcaligenes, and Actinobacillus isolates were not infectious and probably represent secondary invaders. The cultural characteristics of the E. insidiosa isolates conform to those described in the literature, with the exception that the four strains grew in the temperature range 50 F (10 C) to 40 F (4.4 C). Nonspecific toxicities were avoided in assays for botulinum toxin by the protection of mice with chloramphenicol and oxytetracycline.

The agar dilution technique was used for determination of the antibiotic susceptibilities of 57 oral isolates and 2 nonoral isolates of Actinobacillus actinomycetemcomitans. Tetracycline, minocycline, and chloramphenicol inhibited more than 96% of the strains tested at a concentration of less than or equal to 2 micrograms/ml; 89% of the strains were inhibited by 2 micrograms of carbenicillin per ml. The other antimicrobial agents tested were less active. Approximately 10% of the A. actinomycetemcomitans strains were resistant to ampicillin, erythromycin, and penicillin G at concentrations of 32 to 64 micrograms/ml. These data suggest that tetracycline and minocycline may be valuable drugs in the treatment of A. actinomycetemcomitans infections. (+info)Actinobacillosis is a bacterial disease caused by the gram-negative, facultatively anaerobic rod-shaped bacteria Actinobacillus spp. This disease primarily affects animals such as cattle, sheep, and swine, causing symptoms such as abscesses, respiratory distress, and lameness. In rare cases, actinobacillosis can also affect humans, particularly those who have close contact with infected animals or consume contaminated food or water.
In humans, actinobacillosis typically manifests as a localized infection of the skin or mucous membranes, although it can also cause more widespread systemic infections. Symptoms may include fever, chills, fatigue, swollen lymph nodes, and painful abscesses or ulcers at the site of infection. Treatment typically involves antibiotics and surgical drainage of any abscesses.
It is important to note that actinobacillosis is a relatively rare disease in humans, and it is not considered a significant public health concern. However, healthcare providers should be aware of the possibility of this infection in individuals who have close contact with infected animals or consume contaminated food or water.
