A study of the prevalence of Mycobacterium avium subspecies paratuberculosis (MAP) infection in dairy goats was carried out in France, using a serological ELISA. One hundred and five herds were randomly selected in different regions, and all the goats aged six months or older (11,847 goats) were sampled. An estimation had previously been made of the accuracy of the ELISA, and the Rogan-Gladen estimator was used to convert apparent prevalence values into estimates of true prevalence values. Given that sensitivity and specificity at herd level are functions of sample size, and because the sizes of the herds varied considerably, the true prevalence of infection at herd level was estimated using a weighted average depending on the herd size stratum. At the level of the individual animal, the total true prevalence was estimated by applying a weighted average in accordance with the regional distribution of the animals in the target population. At herd level, apparent prevalence and estimated true prevalence were 55.2 and 62.9 per cent, respectively; at individual animal level they were 2.9 and 6.6 per cent, respectively. In herds that were seropositive for MAP, the average within-herd apparent prevalence was 5.9 per cent and the estimated average within-herd true prevalence was 11.1 per cent. [ABSTRACT FROM AUTHOR]

In France, a national surveillance plan to monitor congenital Schmallenberg virus (SBV) outbreaks was set up in January 2012, and has shown that SBV had become widespread throughout the country since mid-2011. However, the number of SBV-infected farms cannot accurately be estimated through congenital SBV reporting alone. Therefore, GDS France (National Animal Health Farmers' Organization) conducted serological investigations in cattle and sheep holdings in several departments in spring 2012 to assess SBV exposure in 2011. A serological study was also conducted in the department of Saône-et-Loire (southern Burgundy) to establish an accurate local overview of circulation of virus in 2011 among cattle. The study was conducted following guidelines elaborated by the French Platform for animal health surveillance. Results indicated differences in within-herd seroprevalence between cattle herds and sheep herds in departments where outbreaks of congenital SBV were reported in early 2012 and a great heterogeneity in seroprevalence between areas (even between areas geographically close to each other). In departments which had been severely affected in early 2012, the overall impact of SBV infection in cattle herds during the 2012-2013 calving season will probably be low. On the other hand, given the low proportion of immunised ewes in sheep SBV outbreaks, sheep flocks which were already affected in early 2012 may once again face congenital cases of SBV [ABSTRACT FROM AUTHOR]

Very few studies have investigated the seasonal aspect of grass pollen sensitisation or its evolution in the allergic canine population. The aim of this study was to evaluate both these aspects. A study of canine grass pollen sensitisation was performed throughout the statistical analysis of 261 intradermal skin testings (IDT=25 allergens tested on average) performed from January 1999 to December 2010. IDTs were performed on dogs with pruritic allergic skin disease. X
2 Tests were used for statistical analysis. Two hundred and thirteen dogs (81.6 per cent) were sensitised to at least one allergen, and 56 (21.5 per cent) to at least one grass pollen. No increase in the rate of positive IDT was recorded over three periods: 1999-2002, 2003-2006 and 2007-2010. No statistical correlation was detected between sex, age or birth month and grass sensitisation. Moreover, no link was found between the season in which the IDT was performed and sensitisation, indicating that there is no seasonality to the sensitisation. However, considering the grasses tested over these three periods (grass mix and rye grass), a clear and significant increase in the percentage of dogs sensitised to grass pollen was observed between 1999-2002 and 2007-2010 (14.4 per cent and 27.7 per cent, respectively). The possible reasons for this sensitisation increase of dogs to grass pollen are discussed. [ABSTRACT FROM AUTHOR]- Published

Numerous cases of tenosynovitis appeared in France causing high morbidity in free-range and standard broilers. The main clinical findings were lameness, stunting and non-uniform bodyweights. Although the natural mortality was low, the economic losses due to birds that had to be removed from the flock prematurely, downgrading of carcases and lower average weights at slaughter were substantial. Postmortem examinations, bacteriological, virological and serological examination confirmed the aetiology of avian orthoreovirus (ARV)-induced tenosynovitis. The isolated ARVs were analysed serologically and genetically. Sequencing of σC RT-PCR products and phylogenetic analysis revealed a new type of ARV. The virus was not neutralised in serum neutralisation test using monovalent sera from vaccinated chickens. Together with the flock data, epidemiology of these recent reovirus outbreaks in France was reconstructed. It is concluded that these reovirus isolates differ serologically and genetically from the well described reovirus isolates used in commercial vaccines which were not capable of preventing the disease. The outbreaks resulted in substantial losses in broilers from vaccinated breeders. [ABSTRACT FROM AUTHOR]

The article focuses on a research paper by Coralie Lupo and colleagues, which examines the postmortem condemnation rate of broilers at slaughter in France. The paper reveals that the overall rate of condemnations was 87 per 10,000 birds, but heavy flocks had a higher rate than standard flocks. It mentions that the common reasons for condemnation were emaciation and congestion of the carcase.

The objective of the study was the safety and efficacy evaluation of a new 450 mg/ml florfenicol formulation in the treatment of naturally occurring respiratory disease when administered intramuscularly, compared with a positive control group treated with the well-established 300 mg/ml formulation. A total of 174 calves, selected from five sites in France and Spain, aged from 1 to 17 months, showing severe signs of respiratory disease, were randomly assigned to treatment with either the 300 mg/ml (3 ml/45 kg; Nuflor; MSD Animal Health) or 450 mg/ml (2 ml/45 kg; Nuflor Minidose; MSD Animal Health) florfenicol formulation, both administered intramuscularly twice, two days apart. Animals were clinically observed daily for 14 days following treatment initiation. The predominant pathogens present in pretreatment respiratory tract samples were Mannheimia haemolytica and Pasteurella multocida. Mycoplasma bovis and Histophilus somni were also present. All isolates were subjected to in vitro sensitivity testing and found susceptible to florfenicol. In both treatment groups, rectal temperature dropped and clinical index (depression and respiratory signs) significantly improved (P<0.05) after treatment. As a result, 97.7 per cent of the 450 mg/ml florfenicol formulation-treated animals were considered treatment successes on day 5. On day 14, 67.82 per cent of the animals were classified as treatment successes and among them 63.22 per cent were cured. The intramuscular injection of the new 450 mg/ml florfenicol formulation was found equally efficacious as the original 300 mg/ml formulation. [ABSTRACT FROM AUTHOR]

BLUETONGUE virus ,GOAT diseases ,CULICOIDES - Abstract
Since 1999, several serotypes of bluetongue virus (BTV) have been isolated in the western part of the Mediterranean basin, and since 2000, Corsica has been exposed to three different serotypes: BTV serotype 2 in 2000, BTV serotype 4 (BTV-4) in 2003 and BTV serotype 16 in 2004. In 2000 there were no surveillance systems for bluetongue, but in 2003, active surveillance of the circulation of BTV and its vector Culicoides species, aided by a raised level of awareness in farmers and veterinarians, made it possible to study the introduction of BTV-4. The monitoring and analysis of the seroconversions of sentinel herds of goats, clinical signs and meteorological variables showed that the serotype had been present in the island since May that year, but clinical signs were first observed only in October. Moreover, the weather conditions and wind patterns were suitable for the transport of Culicoides species from Sardinia in May. These observations suggest that BTV had been transported on air currents from a southern infected area, and that it could have spread without causing clinical signs of disease for a few months.

Between April 2003 and March 2005, 113 outbreaks of histomonosis were recorded in standard turkey farms in France, and 15 cases were recorded in turkey breeding centres. Most of the cases were in north-west France, the principal farming area for turkeys. The majority of the cases occurred during the hottest months, from April to September. Large numbers of cases occurred among birds from four to eight weeks of age, but there were some cases in three-week-old birds and some in birds up to 17 weeks of age. In most of the standard turkey flocks the mortality was less than loper cent, but it was above 30 per cent in nearly 20 per cent of the outbreaks. In the breeding flocks, the average mortality was 60!2 per cent. The size of the flocks, the sex of the birds and the age at which the first clinical signs appeared did not seem to influence the mortality. [ABSTRACT FROM AUTHOR]

An active surveillance programme for transmissible spongiform encephalopathies (TSES) in sheep and goats was implemented in France in 2002 at abattoirs and rendering plants. The analysis of the results of this programme highlighted three biases: a potentially non-random sampling scheme in both rendering plants and abattoirs, a heterogeneous geographical sampling ratio, and the use of two diagnostic tests of unequal sensitivity. Simulations were run to estimate the prevalence of TSES by taking these biases into account. A comparison of the prevalence of TSES calculated from the raw data with the simulation results showed that the effects of non-random sampling were minor in comparison with the effects of the heterogeneous geographical sampling ratio and the use of two diagnostic tests.

Serological data on myxoma virus, rabbit haemorrhagic disease (RHD) virus and RHD-like viruses in juvenile rabbits (Oryctologus cuniculus) trapped in 1995, 1996 and 1997 in two areas of France were analysed. For each disease, the effects of bodyweight, year, month and seropositivity for the other disease were modelled by using logistic regressions. In one area, a model including RHD seropositivity was selected to explain the myxoma virus seropositivity. Models including myxoma virus seropositivity were selected to explain the RHD seropositivity in both areas, and the odds of a rabbit being seropositive to both viruses were 5.1 and 8.4 times higher than the odds of a rabbit being seronegative to myxoma virus and seropositive to RHD. The year and bodyweight had significant effects for myxomatosis in one area and for RHD in both areas. [ABSTRACT FROM AUTHOR]

The overall trend and the trend within birth cohorts of the prevalence of bovine spongiform encephalopathy (BSE) in cattle found dead, euthanased or emergency slaughtered on farms in the Bretagne, Basse Normandie and Pays de la Loire regions of France, during the periods from August 7 to December 22 in 2000, 2001 and 2002, were analysed by non-conditional logistic regression, adjusted for the region and for the type of animals. The overall prevalence of BSE during these three periods decreased from 2.71 per 1000 in 2000 to 1.41 per 1000 in 2001 and 0.42 per 1000 in 2002. The prevalence within birth cohorts started to decrease for the cohort born between July 1, 1995 and June 30, 1996 (cohort 95/96) and the trend was reinforced for cohort 96/97, suggesting that the exposure of animals to the BSE agent had started to decrease for animals born after July 1995, that is, one year before the ban on specified risk materials in meat and bone meal was implemented in France. However, considering that most of the animals would have been infected at between six and 18 months of age, the decrease may have been due, at least partly, to this control measure.

The efficacy of an injectable formulation of danofloxacin (180 mg/ml) in the treatment of naturally occurring bovine respiratory disease was evaluated in field studies on farms in France, Ireland and the United Kingdom. Cattle aged one week to 15 months with clinical respiratory disease were randomly allocated to treatment with 6 mg/kg danofloxacin or 10 mg/kg tilmicosin, administered by a single subcutaneous injection on day 0. A second injection of danofloxacin was administered on day 2, only if predefined clinical criteria were met. Mannheimia haemolytica, Pasteurella multocida and Haemophilus somnus were isolated from pretreatment nasopharyngeal swabs taken on all the farms. After the treatment, there was a more rapid improvement in the clinical response of the 178 animals treated with danofloxacin by day 2 (P<0.01) than in the 90 treated with tilmicosin. For both treatments, there were similar significant (P<0.001) reductions in the mean rectal temperature and severity of clinical signs of abnormal respiration and depression, on days 4 and 10 compared with day 0; 78.1 per cent of the animals treated with danofloxacin and 78.5 per cent of those treated with tilmicosin completed the studies. Danofloxacin 18 per cent was clinically safe and as effective as tilmicosin in the treatment of bovine respiratory disease. [ABSTRACT FROM AUTHOR]

The data obtained from a survey of Mycobacterium bovis infection in wild red deer (Cervus elaphus) and wild boar (Sus scrofa) conducted in France in the 2005/06 hunting season were used to describe and quantify the pathological findings in the two species. The red deer had caseous abscessed lesions in their organs and lymph nodes, whereas in the wild boar the lesions were predominantly caseocalcareous and occurred mainly in the lymph nodes. The severity of the gross tuberculosis-like lesions was estimated on the basis of a numerical score. The significant difference between the distribution of the scores in the two species indicated that the disease was more serious in the red deer than in the wild boar. Unlike the red deer, the wild boar did not show a generalised pattern of disease. Among the lymph nodes examined systematically, gross lesions were most frequently observed in the mesenteric lymph nodes in the red deer and in the retropharyngeal lymph nodes in the wild boar. In both species, the presence of gross lesions showed the closest agreement with the isolation of M bovis from the same lymph nodes. The different patterns of the lesions of tuberculosis in the two species suggest that red deer might play an important role in the intraspecies and interspecies dissemination of the infection, whereas in wild boar the spread of the infection would be more likely to be restricted to other wild boar.

In 2002 and 2003, two successive outbreaks of classical swine fever were declared in wild boar in northern France. The first was in Moselle, near the town of Thionville and the border with Luxembourg, and the second was in the northern Vosges area, near the German border. The outbreaks were investigated by serological and virological diagnosis of dead or shot animals. Hunting restrictions were applied to limit the spread of the outbreaks. The virus was detected eight times between April and July 2002 in the Thionville area, an area well delimited by natural or artificial barriers such as rivers or highways. Cooperation between the authorities concerned was good, and hunting restrictions were applied for one year. No virus was detected after July 2002 and the Thionville outbreak was officially considered over in March 2005. In the northern Vosges the situation was different, with no barriers to animal movements, continuous forest, difficulties in establishing hunting restrictions in this huge area, and the circulation of the virus in Germany close to the frontier. Virus of a different strain from that isolated in the Thionville outbreak was still being isolated in the northern Vosges in 2004, and owing to the failure of the hunting restrictions, the French health authorities decided to vaccinate wild boar.

A total of 404 broiler chicken flocks processed in 15 slaughterhouses in western France were studied to estimate the condemnation prevalence and describe the official reasons for condemnation and the main macroscopic lesions observed in a sample of the condemned carcases. The condemnation rate was 87 per 10,000 birds slaughtered (95 per cent confidence interval 79 to 95 per 10,000) but differed significantly according to the type of poultry produced (standard, light, heavy or certified). The main reasons for condemnation were emaciation and congestion, with rates of 30 and 22 per 10,000 birds slaughtered, respectively. Congestion was significantly associated with arthritis and ascites, whereas infected skin lesions were associated with bruises and abnormalities of colour, odour or conformation.

European bat lyssavirus type 1a (EBLV-1a) was first identified in central France from a serotine bat (Eptesicus serotinus) collected at the end of 2002. Rabies was diagnosed by reference rabies diagnosis methods and molecular tools. Phylogenetic analysis of 14 viral isolates obtained from French bats infected with EBLV-1 between 1989 and the end of 2002 against 47 nucleoprotein sequences showed a north-west to east distribution of EBLV-1a virus and a south to north distribution of EBLV-1b virus, isolates of which could be divided into two groups: group 1 in north-eastern France and group 2 in central and north-western France.

A mandatory reporting system (MRS) was set up in France in December 1990 to detect animals showing clinical signs of bovine spongiform encephalopathy (BSE). Since June 2000, four active surveillance programmes dedicated to fallen stock and slaughtered cattle have been implemented to reinforce the MRS. The clinical status of the cases detected through these programmes was investigated to understand why the MRS had failed to detect them. Up to September 1, 2002, 181 cases had been analysed (126 fallen stock and 55 slaughtered cattle). Almost all the fallen stock cases were animals which had been showing clinical signs, and two thirds of them had shown signs which should have led to a suspicion of BSE. No clinical signs had been reported for two thirds of the slaughtered cattle cases and 10 (8 per cent) of the fallen stock cases. [ABSTRACT FROM AUTHOR]

The first outbreak of trypanosomosis caused by Trypanosoma evansi in camels in France was reported on a farm in the Aveyron Department. Five camels were imported from the Canary Islands to the farm in early July 2006, and trypanosomes were observed on a stained blood smear from one of them, which died in October. On further investigations, trypanosomes were observed in the blood of five camels, three of them indigenous to the farm and two that had been imported. On the basis of microscopical examination (morphological criteria and measurements) and serological results based on the card agglutination Tevansitest and PCR typing, the parasites were identified as Tevansi. After treatment with melarsomine, the infected camels rapidly became negative by parasitological tests and were negative two to four months later by serological tests. The parasite was probably transmitted by tabanids and Stomoxys calcitrans, which were abundant in July to September 2006. No parasites were observed in other animals on the farm or on neighbouring farms, but some of the sheep on these farms were positive by PCR or serology. [ABSTRACT FROM AUTHOR]
