ABSTRACT
To assess the potency of the PPD-mallein produced in Brazil, five animals were from a property identified as a focus of glanders. These animals had suggestive clinical signs of the disease and the other five, from a property free from glanders, showed no clinical signs and were serology negative (control group). PPD-mallein from Burkholderia mallei was obtained by precipitation with trichloroacetic acid and ammonium sulfate. The animals were inoculated according to the criteria established by Department of Agriculture, Livestock and Supply (MAPA) for the diagnosis of glanders. After 48 h of application of PPD-mallein, there was swelling in the area of application, presence of ocular secretion and tears in sick animals. The control group showed no inflammatory reaction at the site of inoculation of PPD-mallein. This immunogen produced in Brazil and still being tested was effective for identifying the infection in true positive animals and excluding the truly negative ones, being a new possibility for diagnosis and control of glanders.
ABSTRACT
The clinical, anatomical and histopatological findings of glanders diagnosis in donkeys in the state of Pernambuco-Brazil are reported. The animals were euthanized and necropsied, and evaluated for lesions in respiratory and lymphatic systems, confirming the disease by isolation of Burkholderia mallei and Strauss test.
ABSTRACT
Three cases of dermatophytosis in free living brown-throated three-toed sloths (Bradypus variegatus) in the Zona da Mata, North of Pernambuco State, Brazil, were studied. Two animals presented areas of alopecia on the pelvic member and thorax and one animal on the pelvic member only. The three animals presented scabs. Hair and scabs samples were submitted to microscopical examination after treatment with a 30 % KOH and cultivated in Mycosel Agar. The direct examination indicated the presence of arthrospores in the hair. Colonies grown after seven days of culture were confirmed as Microsporum based on examination of the structure of the macroconidia. This is the first observation of dermatophytosis caused by Microsporum canis and Microsporum gypseum in free living sloths in the State of Pernambuco.
