Abstract

Leptospirosis is a cosmopolitan infectious disease that causes severe reproductive disorders in cattle, especially those related to abortion. This disease has rodents as main reservoirs; however, cattle are responsible for maintenance of the disease. Thus, the aim of this study was to identify the...

AbstractFull Text

Reproductive efficiency is one of the key elements for any milk production system to be successful. In this regard, reproductive management must be planned properly and the identification of the main reproductive disorders that affect the herd is primordial for decision-making. The aim of the...

Abstract

Neosporosis is primarily a disease of cattle and dogs, but Neospora caninum has been linked to abortion and neonatal mortality in sheep. Since the economic, clinical and epidemiological importance of the infection in sheep remains uncertain, this work investigated the seroprevalence of anti-N....

Abstract

A dairy herd (77 cows) from Rio de Janeiro, Brazil, with a history of tuberculosis infection was tested by a comparative cervical test (CCT). Seventeen cows were reactive and seven were inconclusive (swelling ≥2.0 mm and ≤3.9 mm, respectively). All of these 24 cows were slaughtered and necropsied;...

Abstract

Mycobacterium bovis isolates from an outbreak of bovine tuberculosis in a herd of cattle in Rio de Janeiro, Brazil, were analysed by spoligotyping and variable-number tandem repeat PCR analysis of the mycobacterial interspersed repetitive unit and exact tandem repeats. Molecular typing revealed a...

Abstract

Bovine brucellosis is an important zoonotic disease caused by the bacterium Brucella abortus that leads to economic losses due to animal discard and commercial restrictions. Since positive animals for brucellosis are culled, little is known about the pathogenesis of this disease. Therefore, the...

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

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....

Abstract

The causative agent of bovine tuberculosis (BTB) is Mycobacterium bovis, a bacterium belonging to the M. tuberculosis complex (MTC). The definitive diagnosis is achieved through isolation and identification of M. bovis from clinical samples, using a combination of traditional culture and...

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...
