The goal of this study was to perform a seroepidemiological investigation and to identify risk factors associated with infection of Chlamydophila abortus of sheep herds in the Brazilian state of Alagoas. The study was conducted with samples of 274 ewes with ages equal to or higher than 24 months in 25 herds and in 23 towns located in three regions of the(More)
Mastitis is the principal disease affecting dairy herds worldwide. The aim of the present study was to characterize phenotypic and genotypic features associated with resistance to antimicrobials in Staphylococcus spp. isolated from 2064 milk samples of 525 lactating cows in the Northeast of Brazil. Of the 218 isolates analyzed, 57.8 % were characterized as(More)
The aim of the present study was to isolate and genotype Toxoplasma gondii from pigs slaughtered for human consumption in northeastern Brazil. Indirect immunofluorescence antibody test (IFAT) was used to screen positive pigs. Tissues samples of animals with antibody titers ≥64 were submitted to bioassay in mice. One isolate of T. gondii was obtained, and(More)
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(More)
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(More)
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.
The present study reports the first isolation of Actinobacillus seminis from a goat in Brazil. A four-year-old Moxotó breeding goat in a flock of 70 goats and 65 sheep reared together in the county of Patos, semiarid region of Northeastern Brazil, showed clinical signs of unilateral orchitis and epididymitis. Diagnosis of A. seminis infection was confirmed(More)
Here, we assessed outcome of experimental infection by Neospora caninum in goats intravenously inoculated with 10(6) tachyzoites of the Nc-Spain7 isolate at 40 (G1), 90 (G2) and 120 (G3) days of gestation. Infected goats had fever between 5 and 9 days post inoculation (dpi); all were seropositive at the time of abortion/birth. Foetal death occurred in G1(More)
The aim of this study was to detect the IS900 region of Mycobacterium avium subsp. paratuberculosis (MAP) in bovine milk samples using real-time polymerase chain reaction (qPCR) and conventional PCR, and to study the agreement between these tests. A total of 121 bovine milk samples were collected from herds considered positive for MAP, from the State of(More)
The aim of the present study was to determine the prevalence and risk factors associated with Campylobacter fetus subsp. venerealis and Tritrichomonas foetus infection in cows from dairy herds in the state of Pernambuco, Brazil. In total, 383 samples of cervico-vaginal mucus were collected from cows on 21 herds in 19 districts. Genomic DNA was extracted(More)
