The Theileria parva carrier-state in cattle on commercial farms on Zimbabwe was investigated using parasitological and serological methods. The proportion of cattle showing Theileria piroplasms on two farms, which had recent histories of disease outbreaks, were 64% (n = 106, total of heifers and weaned calves examined) and 71.5% (n = 60) while the proportion of T. parva antibodies for the same ...

On 15 Swiss poultry farms, broiler flocks, other farm animals, and the environment were examined during consecutive rearing periods to investigate the occurrence and genetic diversity of Campylobacter. Of the 5154 collected samples, 311 (6%) from 14 farms were Campylobacter positive by culture. Amongst the positive samples, 228 tested positive for Campylobacter jejuni and 92 for Campylobacter c...

BACKGROUND In 2010, foot-and-mouth disease (FMD) occurred for the first time in a decade in Japan. Movement or shipment of people and animals around infected farms was restricted; however these contingency measures proved insufficient to prevent FMD spread. Consequently, a total of 292 farms were confirmed as infected during this outbreak. We conducted a case-control study to identify the risk ...

Enterobacteriaceae-associated blaCTX-M genes have become globally widespread within the past 30 years. Among isolates from Washington State cattle, Escherichia coli strains carrying blaCTX-M (CTX-M E. coli strains) were absent from a set of 2008 isolates but present in a set of isolates from 2011. On 30 Washington State dairy farms sampled in 2012, CTX-M E. coli prevalence was significantly hig...

A cross-sectional survey was undertaken on 240 dairy cattle farms in Nyandarua District in central Kenya to determine farm characteristics, farmer’s perception of production constraints and diseases and the prevalence and control practices for ticks and helminths. Farmers were interviewed using questionnaires and 708 cattle examined. The mean farm size was 3.2 hectares and average number of cat...

Distribution of Anaplasma spp., Babesia spp., Theileria spp., and Ehrlichia ruminantium, was for the first time studied in Bié Province, central Angola. We examined 76 blood samples of cattle originated from seven farms, and 13 blood samples of goats from two farms employing molecular genetic tools (PCR). Most prevalent was A. ovis-infection in goats (100%) and A. marginale-infection in cattle ...

The technical efficiencies of a sample of extensive Iranian cattle farms collected by Ministry of Agriculture were analyzed using a nonparametric Data Envelopment Analysis (DEA) model. Mean pure technical efficiency in a DEA model in which all variables were normalized with the number of cows was 0.79, indicating that there is ample potential for more efficient input utilization in cattle farmi...

In recent years, extended-spectrum β-lactamases (ESBL) producing bacteria have been found in livestock, mainly as asymptomatic colonizers. The zoonotic risk for people working in close contact to animal husbandry has still not been completely assessed. Therefore, we investigated the prevalence of ESBL-producing Escherichia spp. in livestock animals and workers to determine the potential risk fo...

This study aimed to analyze the financial impact of foot-and-mouth disease (FMD) outbreaks in cattle at the farm-level and the benefit-cost ratio (BCR) of biannual vaccination strategy to prevent and eradicate FMD for cattle in South Vietnam. Production data were collected from 49 small-scale dairy farms, 15 large-scale dairy farms, and 249 beef farms of Long An and Tay Ninh province using a qu...

Background: Q fever is a zoonotic disease caused by Coxiella burnetii. In Colombia it is not a notifiable disease in humans and is most likely under diagnosed. There are no studies about its prevalence in important reservoir species, such as cattle. Objective: the aim of this study was to investigate the frequency of C . burnetii infection in cattle farms and determine the frequency of antibodi...
