Background: Leptospirosis is a worldwide distributed zoonotic disease which affects humans and animals in countries with humid, tropical and subtropical climates. It is a well known cause for abortion, stillbirth or birth of weak calf. The present study was performed to investigate the...

Pharmacokinetics/pharmacodynamics ratios of enrofloxacin HCl-2H₂O (enro-C) in cows to treat bovine leptospirosis prompted this clinical trial in the highlands (HL) and the tropics (TL) in Mexico. In the HL, 111 Holstein-Friesian cows were included and 38 F1 Zebu-Holstein/Friesians in the TL....

Two experiments were conducted to evaluate the impact of two vaccines on the reproductive performance of multiparous beef cows in Mato Grosso do Sul, Midwest Brazil. In Experiment 1,765 calved multiparous Nellore cows were subjected to the same fixed-time artificial insemination (FTAI) protocol and ...

Bovine Genital Leptospirosis (BGL) is an important syndrome that leads to reproductive failures. The present study aimed to perform a molecular analysis of Leptospira spp. identified from genital and urine samples from in vivo naturally infected cows with poor reproductive performance. A total of...

The enzootic bovine leucosis (EBL) and bovine leptospirosis are infectious diseases that have a negative economic impact on the cattle industry. Diagnosis is carried out by detection the specific antibodies. There are not studies correlating either serological results for EBL and leptospirosis in...

The productivity of cattle farms is affected by infectious and noninfectious factors that generate economic losses and cause reproductive failure represented by low conception rates, embryonic mortality, abortions, and fetal mummification. The infectious agents that most impact the reproductive...

Beef cattle farming is a highly representative activity for the GDP of Brazil, rendering the country an important producer of beef. For Brazil to maintain this prominent position, sanitary management actions must be carried out, such as th e control of reproductive diseases. This study examines the ...

Bovine genital leptospirosis (BGL) is characterized by silent chronic reproductive disorders, most related to early embryonic death leading to estrus repetition, subfertility and abortions. However, most studies were conducted in slaughterhouses, which lacks reproductive and sanitary history of the ...

Introduction: Leptospirosis is a neglected zoonosis in developing countries including Egypt where its burden is underestimated. Methodology: A cross sectional study was carried out to estimate the seroprevalence and associated risk factors of Leptospira interrogans serovar Hardjo infection among ...
