This study presents a Brazilian goat herd with reproductive failure over 2009-2010, in which there were abortions (22/50; 44%), embryonic resorption (6/50; 12%) and neonatal deaths (2/50; 4%). A diagnosis of leptospirosis was made, based on serology (microscopic agglutination test - MAT), bacterial culture, and polymerase chain reaction (PCR). Antibiotic(More)
The aim of the present study was to consider the wide usage of urinary PCR as an increasingly useful tool for an accurate diagnosis of leptospirosis in livestock. A total of 512 adult animals (300 cattle, 138 horses, 59 goats and 15 pigs), from herds/flocks with reproductive problems in Rio de Janeiro, Brazil was studied by serology and urinary PCR. From(More)
All over the world, leptospirosis has been reported as one of the major causes of reproductive failure in cattle and other ruminants, determining abortions, stillbirth, weak newborns and decrease in their growth rate and milk production. Nevertheless, despite its importance, it is still a challenging disease, from what scarce information about epidemiology,(More)
The objective of this study was to demonstrate the presence of leptospires in equine urine, as evidence for a potential role of horses in transmission of this organism. Thoroughbred horses (aged 2-5 years, n = 276) from Rio de Janeiro, Brazil, were studied. After a severe storm, the premises of the animals remained flooded for 72 h. Blood samples for(More)
