serologic evidence for bovine immunodeficiency virus infection in france. | we report herein on the first serologic detection of antibodies to bovine immunodeficiency virus (biv) in france. serum samples from dairy and beef cattle from southwestern and western france (landes and vendée) were tested using a western blot assay with a recombinant 53 kda gag precursor derived from the louisiana biv r29 isolate. we performed our study on the oldest animals from 37 different herds that were under serologic follow up for previous bovine leukemia virus infection. overall, 398 s ... | 1996 | 8701572 |
prevalence of cryptosporidium infection in calves in france. | two multicentre surveys were conducted in france to estimate the prevalence of cryptosporidium infection in calves using qualitative elisa for detection of cryptosporidium coproantigens and oocysts. the first survey involved 4-12-day-old calves in six dairy-calf distribution centres, collecting calves from seven administrative regions (aquitaine, bretagne, franche-comté, lorraine, normandie, nord, pays de loire). for each region, 20 calves were selected every month for 12 consecutive months (oct ... | 2000 | 10729640 |

inventory of wild rodents and lagomorphs as natural hosts of fasciola hepatica on a farm located in a humid area in loire atlantique (france). | with the objective of studying the role of wild fauna in the epidemiology of fasciolosis disease, a definitive wild-host inventory was carried out in a french farm where infected domestic hosts (cows) cohabit with wild potential ones. liver flukes, faecal eggs and antibodies were looked for in lagomorphs (oryctolagus cuniculus) and rodents (myocastor coypus, ondatra zybethicus, rattus norvegicus, arvicola sapidus and micromammal species) trapped in the study area. presence of fasciola hepatica w ... | 2000 | 10887652 |
babesia divergens in france: descriptive and analytical epidemiology. | babesia divergens cause of bovine babesiosis transmitted by ixodes ricinus, is widely spread especially in west, central and south-west parts of france. it occurs with two annual peaks, in spring and autumn. the study was carried out during a period of two years (1991-1993) in four farms in the sarthe area, in order to know the distribution and the ecology of i. ricinus, and to show the presence of b. divergens. cattle are parasitised as early as march essentially by adult ticks, according to a ... | 1999 | 11071546 |
targeted surveillance to assess the prevalence of bse in high-risk populations in western france and the associated risk factors. | a pilot study was set up for the first time in france in august 2000, to obtain more precise estimates on the bse epidemic in france. three categories of cattle at risk of bse (found dead on-farm, euthanased and emergency slaughtered) were sampled exhaustively from august 7 to december 22, 2000, in the three regions assumed to be the most affected with bse in france (basse-normandie, bretagne and pays de la loire). the samples were checked by using prionics tests, and positive samples were confi ... | 2002 | 12166421 |
how the surveillance system may bias the results of analytical epidemiological studies on bse: prevalence among dairy versus beef suckler cattle breeds in france. | until recently, epidemiological studies on bovine spongiform encephalopathy (bse) were based on mandatory reporting systems (mrs) of clinically suspect bovines only, but rapid diagnostic tests were validated in 1999 and are used for targeted surveillance in switzerland, france and other countries, as a complementary and secondary tool. data on 30491 cattle issued from a french pilot program targeted at cattle having died on the farm, subjected to euthanasia or sent for emergency slaughter, did n ... | 2003 | 12657210 |
descriptive spatial analysis of bse in western france. | the spatial heterogeneity of bovine spongiform encephalopathy (bse) was analysed on the 84 cases confirmed in western france (wf) between august and december 2000, when both the mandatory reporting system and an active surveillance on cattle at risk were running. ninety-four percent of these cases were born between june 1993 and june 1996, and we analysed the location at birth. one disease mapping and two clustering methods (scan of kulldorff and the method of besag and newell) were used. in ord ... | 2003 | 14746770 |
incidence of respiratory disorders during housing in non-weaned charolais calves in cow-calf farms of pays de la loire (western france). | we assessed the incidence rate of respiratory disorders during the 1999-2000 housing period in non-weaned calves reared in a specific cow-calf farming system in western france, examined its variations according to age of the calf, housing facility and meteorological conditions, and described the different time-distribution patterns of incident cases within the barns. treatments for respiratory disorders were recorded by the farmers on a specific sheet according a written definition provided. a c ... | 2004 | 15158575 |

genotypic and phenotypic detection of macrolide and lincosamide resistance in streptococcus uberis. | streptococcus uberis isolates (n = 55) were obtained from milk samples of cases of mild clinical mastitis in 55 dairy cows from 35 herds serviced by one veterinary practice in mayenne, france. isolates were tested for macrolide and lincosamide resistance by using phenotypic and genotypic methods. erythromycin resistance was detected in 12 of the 55 (22%) isolates based on agar disc diffusion testing and mic measurements, and was encoded by ermb. this gene also conferred phenotypic resistance to ... | 2007 | 17954749 |
serological evidence of caprine herpesvirus 1 infection in mediterranean france. | caprine herpesvirus 1 (cphv-1) is responsible of a systemic disease in kids and genital diseases inducing abortions in adult goats. in europe, cphv-1 is widespread in mediterranean countries such as greece, italy and spain. as france is geographically close to these countries, a survey was conducted to investigate the presence of cphv-1 in goats in a mediterranean department (corse-du-sud) and in continental departments (dordogne and vendée) of this country. taking into account the close antigen ... | 2008 | 18031957 |
a case-based learning approach for teaching undergraduate veterinary students about dairy herd health consultancy issues. | a case-based learning (cbl) format was implemented at the veterinary school of nantes, france, for veterinary students in their last year of the curriculum who had chosen to track toward a farm animal career. the focus of the cbl format was learning about dairy herd health consultancy. the goal was to emphasize teamwork among students, introduce professional communications and advisory relationships with clients, and work within the technical and economic limitations of participating farms. thes ... | 2009 | 19435987 |
molecular epidemiology of pasteurella multocida in dairy and beef calves. | the molecular epidemiology of pasteurella multocida has rarely been studied at the farm level in cattle. the aim of this study was to determine whether single or multiple strains of p. multocida tend to exist within farms. molecular characterisation was carried out on isolates obtained from nasal swabs from 105 calves from 32 randomly selected beef and dairy farms located throughout scotland, and from 131 calves from 20 farms in the mayenne region of france, where sampling occurred in response t ... | 2011 | 21511409 |
