In a 2-year longitudinal study of adult animals on 15 dairy farms and four sheep farms in Lancashire, UK. C. jejuni was isolated from all farms, although not on every occasion. Faecal samples were collected and cultured using standard techniques for isolation of Campylobacter. Assignment to species was via PCR assays. Peak prevalence of C. jejuni in both cattle and sheep was observed during the...

Fecal samples from 335 dairy farm residents and 1458 cattle on 80 farms were tested for Vero cytotoxin (VT)-producing Escherichia coli (VTEC). Residents were also tested for antibodies to VT1 and O157 lipopolysaccharide (LPS). Residents and cattle on farms with VTEC-positive persons or E. coli O157:H7-positive cattle were retested. Twenty-one persons (6.3%) on 16 farms (20.8%) and 46% of cattle...

Infectious bovine rhinotracheitis-Infectious pustular vulvovaginitis (IBR/IPV) virus was isolated and identified from a herd of cattle and buffaloes, suffering from respiratory and genital disorders during May 2007. These animals were located at Giza Governorate with a total number of 350, (200 in open farms and 150 in closed farms). Vaginal, nasal and ocular swabs were collected (136 samples w...

This cross-sectional study evaluated risk factors associated with farm-level bovine leukemia virus (BLV) seropositivity in 563 dairy and 490 beef farms throughout Japan. Twenty randomly selected cattle on each farm were serologically tested, and farm epidemiologiocal information was obtained through face-to-face interviews. Due to the large number of zero-prevalence dairy and beef farms, data a...

The objective of this study was to determine whether dairy farms with poor cow welfare could be identified using a national database for bovine identification and registration that monitors cattle deaths and movements. The welfare of dairy cattle was assessed using the Welfare Quality(®) protocol (WQ) on 24 Portuguese dairy farms and on 1930 animals. Five farms were classified as having poor we...

Bovine neosporosis caused by the apicomplexan protozoan parasite N. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. The aim of this study was to determine the seroprevalence of N. caninum infection in industrial dairy cattle of Hamedan province (west of Iran) by ELISA method. Blo...

During the period from September 1996 through November 1996, 10 Dutch dairy farms were visited to collect fecal samples from all cattle present. The samples were examined for the presence of verocytotoxin (VT)-producing Escherichia coli (VTEC) of serogroup O157 (O157 VTEC) by immunomagnetic separation following selective enrichment. Cattle on 7 of the 10 dairy farms tested positive for O157 VTE...

Fasciolosis is an important helminth disease of livestock and other ruminants. A cross sectional study to determine the prevalence of Fasciola gigantica in cattle was carried out in 9 randomly selected farms and 1 slaughter house between February and May 2012. Faecal and blood samples were collected from 186 cattle in the farms and 200 cattle at slaughter. The faecal samples were analysed using...

Mycobacterium avium subsp. paratuberculosis (Map) causes Johne's disease, with large economic consequences for dairy cattle producers worldwide. Map spread between farms is mainly due to animal movements. Locally, herd size and management are expected to influence infection dynamics. To provide a better understanding of Map spread between dairy cattle farms at a regional scale, we describe the ...

Aim This study focuses on the risk factors associated with the prevalence of Fasciola affecting cattle population in three provinces belonging to the Nile Delta of Egypt and to estimate the economic losses as a result of fascioliasis. Materials and Methods From January 2015 to end of December 2015, records of 21 farms (4976 cattle) were analyzed to screen the prevalence of fascioliasis among ...
