Abstract Bartonella spp. are facultative intracellular bacteria associated with several emerging diseases in humans and animals. B. henselae causes cat-scratch disease is increasingly other syndromes, particularly ocular infections endocarditis. Cats the main reservoir for transmitted to cats by cat fleas. However, new potential vectors suspected of transmitting henselae, particular, Ixodes ricinus, most abundant ixodid tick that bites western Europe. We used a membrane-feeding technique...
• Main behaviours of dairy cows were successfully predicted using accelerometer data. EXtreme Gradient Boosting followed by the Viterbi algorithm led to best results. Postures are most difficult discriminate with an on neck. 86 Holstein from 4 farms equipped and observed leading a large dataset. Independent signal sequences stratification used validate models.
Although Babesia divergens is the principal confirmed zoonotic sp . in Europe, there are gaps our knowledge of its biology and transmission by tick Ixodes ricinus In order to reproduce part parasite cycle that occurs vector, an vitro animal skin feeding technique on blood containing cultivated B. was developed. Parasite DNA detected all samples salivary glands nymphs adults had fed parasitized as larvae nymphs, respectively, indicating acquisition well a transtadial persistence PCR performed...
Abstract We report in vitro culture of zoonotic Babesia sp. EU1 from blood samples roe deer France. This study provides evidence transovarial and transstadial transmission the parasite within Ixodes ricinus, which suggests that this tick could be a vector reservoir EU1.
We report 2 cases of babesiosis in immunocompetent patients France. A severe influenza-like disease developed both weeks after they had been bitten by ticks. Diagnosis was obtained from blood smears, and Babesia divergens identified PCR 1 case. Babesiosis Europe occurs healthy patients, not only splenectomized patients.
Anaplasma ovis is a major cause of small ruminant anaplasmosis, tick-borne disease mainly affecting ruminants in tropical and subtropical regions the world. Due to health production problems dairy goat flocks Corsica, France, demonstration A. infection some animals, an extensive survey was conducted island spring 2016. The aim determine prevalence geographical distribution infections goats ticks as well possible relationships with anaemia other indicators. In addition, genetic diversity...
Our aim in this study was to investigate whether the behaviors of dairy cows on pasture, predicted with accelerometer data and combined GPS data, can be used better understand relationship between pasture characteristics. During spring 2018, 26 Holstein were equipped a 3D-accelerometer sensor fixed neck-collar for five days. The grazed alternatively permanent temporary grasslands. structural elements, soil moisture, slope botanical characteristics identified. Behaviors every 10 s from data....

Abstract To determine characteristics of natural transmission Babesia sp. EU1 and B. divergens by adult Ixodes ricinus ticks, we examined tick salivary gland contents. We found that I. is a competent vector for their sporozoites directly invade erythrocytes. conclude naturally transmitted ricinus.
Fasciolosis is a re-emergent parasitic disease of worldwide significance with major global impact on livestock health and production. In the French Mediterranean island Corsica, fasciolosis has been recognized for long time but little known about its dynamic as main investigations are outdated. Three compartments - definitive domestic hosts, intermediate hosts environment involved in transmission were studied by applying an integrative extensive approach: (1) farm abattoir surveys, (2) snail...
Faecal egg counts (FEC) and the FEC reduction test (FECRT) for assessing gastrointestinal nematode (GIN) infection efficacy of anthelmintics are rarely carried out on ruminant farms because cost individual analyses. The use pooled faecal samples is a promising method to reduce time costs, but few studies available cattle, especially evaluation different pool sizes FECRT application. A study was conducted assess strategies based using evaluate pen-side portable FEC-kit assessment cattle...
Macrophages, eosinophils, neutrophils and lymphocyte subpopulations (OvCD5+, OvCD4+, OvCD8+, OvWC1+ lg+) were identified in sections of hepatic tissue lymph nodes from sheep experimentaly infected with F. hepatica necropsied 14, 28, 42 or 56 days post infection. The migratory tunnels produced by juvenile flukes appeared as focal areas necrosis surrounded infiltrating inflammatory cells, particularly numerous macrophages, eosinophils OvCD4+ lymphocytes. In addition, B proliferation was...
