Abstract

Background: The south of Chile constitutes the main cattle milk producing area of the country. Regarding leptospirosis control in Chile, there is neither an official program nor an epidemiological characterization of smallholder dairy farms. This study was carried out to determine Leptospira...

Abstract

Background: Although Leptospira isolation has been reported in Chilean cattle, only serological evidence of serovar Hardjo bovis infection has been routinely reported. The present report provides characterization of the pathological presentation and etiology of a clinical case of leptospirosis in a ...

Abstract

The study was conducted to determine the genetic diversity of 22 bovine viral diarrhoea virus (BVDV) strains isolated from infected cattle from Peru (n=15) and Chile (n=10). The phylogenetic analysis based on the 5′ UTR showed that all 25 strains belonged to genotype 1. A total of 23 strains could...

Abstract

This paper describes an ELISA test using blood serum samples to detect dairy cattle persistently infected with BVDV in 9 dairy farms in the 10th region of Chile. It was shown that 0.3% of the serum samples were positive to the ELISA test and 33.3% of the dairy herds had persistently infected...

Abstract

Bovine viral diarrhoea virus (BVDV) has a worldwide distribution and most cattle are seropositive, although the prevalence may vary among herds and among different age groups. Persistently infected (PI) animals are the most efficient transmitters of infection often remaining unnoticed in the herds, ...

Abstract

In southern Chile (regions IX and X) serum samples were obtained from 200 representative herds; 45 (14.5%) of the 310 cattle sampled in 14 herds were positive to the immunodiffusion test for bovine leukosis. In these 14 herds, 63 cattle (20.3%) had positive neutralization titres for IBR IPV virus....

Abstract

Serum samples from 2864 cattle were analysed for antibodies against PI-3 by haemagglutination inhibition and against BDV, BHV-1 and BRSV by virus neutralization. The herd seroprevalence was 100% for BDV, PI-3 and BRSV and 91.7% for BHV-3. The individual seroprevalences were 50.9, 41.0, 97.1 and...

Abstract

Bovine viral diarrhoea/Mucosal disease (BVD/MD) is a worldwide viral disease with a great impact in bovine reproduction and production. In Chile, the disease has been reported with over 60% prevalence and it demands adequate diagnostic methods. Currently the official serological diagnostic test in...

Abstract

The presence of both enterotoxic and cytolethal distending toxin (CLDT) factors were established in 13 strains of C. jejuni and 8 of C. coli isolated from bovine faeces. The ligated rat intestinal loop test and HeLa cell cultures, respectively, were used. 7.7% of culture filtrates obtained from C....

Abstract

In neutralization tests for bovine diarrhoea/mucosal disease (BVD/MD) seroprevalence on 948 cow serum samples collected from 40 large herds of the IXth and Xth Regions in southern Chile, and on 116 bulls, 700 of the 948 cows were positive (73.8%) at a titre of ≥ 1:5. The herd seroprevalence was...
