This report describes the epizootiology, clinical presentation, diagnosis and treatment of an outbreak of leptospirosis caused by Leptospira canicola in feedlot calves. The infection appeared to be of high morbidity with a cumulative clinical incidence of 15.6%, cumulative subclinical incidence of 39% and high mortality (8.3%). Clinical disease was diagnosed in 4-8-month-old calves, while subcl...
leptospirosis is one of the main causes of acute febrile illness and is presumed to be the most widespread zoonotic disease in the world. cattle populations may be infected with serovars hardjo, pomona and grippotyphosa. infection with icterohaemorrhagiae, bratislava, hebdomadis, autumnalis, australis, sejroe, canicola and bataviae serovars also occurs. in this study, 200 serum samples were col...
A 5-year-old male cross-bred guard dog with signs of anorexia, vomiting and jaundice was referred to Small Animal Hospital, Faculty of Veterinary Medicine, University of Tehran. Initial diagnostic laboratory tests revealed leukocytosis, thrombocytopenia, haemoconcentration, azotaemia, high liver enzyme activities, proteinuria and bilirubinuria. Aggressive therapeutic procedures failed to improv...
AIM This study was taken up to develop an indirect enzyme-linked immunosorbent assay (i-ELISA) for screening antibodies against Leptospira spp. in canines. MATERIALS AND METHODS An i-ELISA was developed using outer membrane protein extracted from Leptospira interrogans serovar canicola used for coating the well with concentration of 0.5 µg/µl. A total of 250 serum samples from clinically affe...
White-tailed deer (Odocoileus virginianus) are commonly exposed to disease agents that affect livestock but environmental factors that predispose deer to exposure are unknown for many pathogens. We trapped deer during winter months on two study areas (Northern Forest and Eastern Farmland) in Wisconsin from 2010 to 2013. Deer were tested for exposure to six serovars of Leptospira interrogans (gr...
A polymerase chain reaction (PCR)-based assay which amplifies repetitive DNA elements present within bacterial genomes was used to characterize and differentiate Leptospira sp. Thirty-five strains from a reference culture collection and 18 clinical isolates which had been previously analyzed by cross agglutinin absorption test (CAAT) were evaluated by this technique. PCR results from analysis o...
A serologic, bacteriologic, and histopathologic examination for leptospires was carried out on 89 armadillos (Chaetophractus villosus) from Argentina. Forty-seven per cent of the serum samples yielded positive results when tested by microscopic-agglutination. Predominant agglutination reactions were to the Hebdomadis and Bataviae serogroups. A total of 15 Leptospira isolations (from 16.8 per ce...
The results of the administration to healthy beagles of a secondary antigenic stimulus (booster dose) of Leptospira canicola and infectious canine hepatitis virus (ICH) are reported. Twelve previously vaccinated animals were used. Six were exposed to a 335 r dose of x-irradiation. Three controls and three irradiated dogs received the booster dose two days after the irradiation and the remaining...
Leptospirosis is a worldwide zoonosis which is responsible for the typical form of Weil's disease. The epidemiological surveillance of the Leptospira species agent is important for host prevalence control. Although the genotyping methods have progressed, the identification of some serovars remains ambiguous. We investigated the multispacer sequence typing (MST) method for genotyping strains bel...
