Prevalence of in Algeria and Characterisation of the Isolated Clones.

Bovine respiratory disease (BRD) is common in calves in Algeria, but to date, has never been monitored as a potential etiological agent. Here, to assess the presence (direct detection) and circulation (indirect detection) of , broncho-alveolar lavage fluids (BALF) and serum samples were collected from 60 veal calf farms in Algeria. A commercial ELISA kit (ID Screen ELISA) was used to screen for the presence of specific antibodies against .

Monitoring Diversity and Antimicrobial Susceptibility in Calf Feedlots Undergoing a Respiratory Disease Outbreak.

Bovine respiratory diseases (BRD) are widespread in veal calf feedlots. Several pathogens are implicated, both viruses and bacteria, one of which, , is under-researched. This worldwide-distributed bacterium has been shown to be highly resistant in vitro to the main antimicrobials used to treat BRD.

Monitoring the Decrease in Susceptibility to Ribosomal RNAs Targeting Antimicrobials and Its Molecular Basis in Clinical Mycoplasma bovis Isolates over Time.

Mycoplasma bovis is considered an emerging threat to bovine production in industrialized countries. Its control depends on good husbandry and efficient chemotherapy practices. In France, clinical isolates collected after 2009 showed a drastic loss of susceptibility to most antimicrobials when compared with isolates collected in 1978-1979.

Alterations in the Quinolone Resistance-Determining Regions and Fluoroquinolone Resistance in Clinical Isolates and Laboratory-Derived Mutants of Mycoplasma bovis: Not All Genotypes May Be Equal.

Mycoplasma bovis is considered a major contributor to respiratory diseases in young cattle. Resistant M. bovis isolates have increasingly been reported worldwide due to extensive use of antimicrobials to treat bovine pneumonia.

Loss of diversity within Mycoplasma bovis isolates collected in France from bovines with respiratory diseases over the last 35 years.

Mycoplasma (M.) bovis has recently emerged as a major, worldwide etiological agent of bovine respiratory diseases leading to huge economic losses mainly due to high morbidity and mortality as well as poor growth rates. The spread of M.

Validation of BdCCp2 as a marker for Babesia divergens sexual stages in ticks.

Babesiosis is a tick-transmitted disease of mammalian hosts, caused by the intraerythrocytic protozoan parasites of the genus Babesia. Transmission of Babesia parasites from the vertebrate host to the tick is mediated by sexual stages, the gametocytes which are the only intraerythrocytic stages that survive and develop inside the vector. Very few data are available concerning these parasite stages and some markers are needed in order to refine our knowledge of Babesia life cycle inside the tick and to permit the monitoring of parasite transmission from vertebrate to vector.

Development of a multiplex real-time PCR for contagious agalactia diagnosis in small ruminants.

Contagious agalactia is an important disease worldwide that affects small ruminants. Clinical manifestations vary from mastitis, pneumonia, arthritis and keratoconjunctivitis to septicemia. Four mycoplasmal etiological agents have been identified: Mycoplasma (M.

A Vegetation Index qualifying pasture edges is related to Ixodes ricinus density and to Babesia divergens seroprevalence in dairy cattle herds.

Babesia divergens, transmitted by the tick Ixodes ricinus, is the main agent of bovine piroplasmosis in France. This Apicomplexa often is present in asymptomatic carriers; however, clinical cases are rare. While numerous factors are known to influence tick density, no risk factor of contact with B.

Natural transmission of Zoonotic Babesia spp. by Ixodes ricinus ticks.

To determine characteristics of natural transmission of Babesia sp. EU1 and B. divergens by adult Ixodes ricinus ticks, we examined tick salivary gland contents.
