Some common agents were tested for their effectiveness against Corynebacterium pyogenes. The pathogen proved most susceptable to Wofasteril. All germs were killed within ten minutes by a 0.005% solution. Equally good action was recorded from all the other tested agents as well (lactic acid, Lugol's solution, formalin, cupric sulphate, alcohol, and aethacridine. Other studies were conducted with the view to testing the survival capacity of Corynebacterium pyogenes in different media and storage conditions. The pathogen survived three months in routine media and mastitis secretion at room temperature. Regrowth of 38 in 50 strains took place after nine months of refrigerator storage in slanting blood agar tubes with paraffin plugs. Germs sampled from mastitis secretion and stored in a refrigerator were cultivable even after one year had elapsed. The detectability rate of Corynebacterium pyogenes did not change over months by storage of wound infection material at 12 degrees C below zero. The pathogen remained detectable five days from artificial contamination of cattle skin. 相似文献

Abstract Extract Feild outbreaks of acute lameness in sheep in New Zealand are usually attributed to contagious footrot (Fusiformis nodosus) (Beveridge, 1941), foot abscess (Sphaerophorus necrophorus) (Gregory, 1939), or so-called “nutritional scald” Occasionally Erysipelothrix rhusio pathiae is also responsible (Whitten, 1951). 相似文献

Cystitis and vulvovaginitits, due to Corynebacterium pilosum and Actinomyces pyogenes infection in a 2-month-old female calf, is described. The prominent clinical signs were urinary incontinence, adherence of triple phosphate crystals to the vulvar hair and ulceration on the vulva, the ventral side of the tail skin and the perineum. Only a mild inflammation of the bladder mucosa and submucosa was seen on histological examination. 相似文献

A 2-year-old, neutered, male cat was euthanatized because of difficult repiration and inability to rise. Necropsy revealed pyothorax. Corynebacterium pyogenes was grown from the purulent thoracic exudate. A Borrelia-like microorganism was demonstrated in the exudate, using phase-contrast microscopy. 相似文献

Chronic esophagitis due to Pythium insidiosum infection caused weight loss, dysphagia, and hypersalivation in 2 dogs from rural Tennessee. Although dog 1 presented for evaluation in December 1984 and dog 2 in October 1992, infection likely occurred during the previous summer by drinking fresh pond water containing zoospores. Hematologic testing revealed eosinophilia and hypergammaglobulinemia in one dog. An etiologic diagnosis was not made until postmortem evaluation when hyphae within necrotic and granulomatous cellular infiltrates in the esophageal wall were identified as P insidiosum by immunoperoxidase staining. Failure to culture the organism from the esophageal wall in dog 2 was attributed to refrigeration of the tissues, since refrigeration decreases the survivability of P insidiosum.
