Abstract

Although prevalent, the exact impact of infectious diseases on reproductive failures remains to be determined. Among them, leptospirosis has commonly been reported as cause of abortions on outbreaks. Nevertheless, the majority of the animals present a chronic, silent form of the disease, which is...

Abstract

Bovine leptospirosis causes substantial reproductive failure in cattle, mainly due to infections with serovar (sv) Hardjo infection. Notwithstanding, other serovars from the serogroup (sg) Sejroe could also have important roles in bovine leptospirosis. The objective was to investigate genetic...

AbstractFull Text

For a long time, it has been stated that urine leptospiral shedding is intermittent, which was observed primarily by culturing. However, culturing presents serious limitations, mainly low sensitivity, and failure on detection of leptospires cannot be neglected. PCR presents several advantages,...

Abstract

Bovine leptospirosis is an important infectious disease that causes reproductive problems and economic risks, particularly in the tropics. The present study aimed to determine the extent of Leptospira infection among bovines on a slaughterhouse from Rio de Janeiro, Brazil via serological,...

Abstract

Leptospirosis is a worldwide zoonotic disease determined by pathogenic spirochetes of the genus Leptospira. The control of bovine leptospirosis involves several measures including antibiotic treatment of carriers. Despite its importance, few studies regarding antimicrobial susceptibility of strains ...

Abstract

Leptospirosis in bovines is in majority determined by the host-adapted serovars, mainly Hardjo (types Hardjoprajitno and Hardjobovis), that belong to the serogroup Sejroe. Members of other serogroups as Pomona and Tarassovi have been eventually reported, mainly when outbreaks occurs. Nevertheless,...

Abstract

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...

Abstract

Leptospirosis in cattle is characterized by causing significant economic losses due to reproductive problems as well as drop in production of meat and milk. Subsequent abortion may be caused by the persistence of the agent in the reproductive tract and thus become a possible transmission source....
