Experimental Infection of Captive Red Foxes () with .

In Europe, animal tuberculosis (TB) due to involves multi-host communities that include cattle and wildlife species, such as wild boar (), badgers () and red deer (). Red fox () infections have also been recently reported in some TB endemic regions in the Iberian Peninsula and France, with some of the infected animals shedding in urine and feces. In order to understand the pathogenesis of infection in foxes and the associated risk of transmission, 12 captive foxes (6 females and 6 males) were inoculated orally with 2 × 10 colony-forming units of a French field isolate of .

Interferes with Bovine Tuberculosis Surveillance.

, a member of the complex, was originally described as the cause of tuberculosis in wild rodents. However, in the last few years, an increasing number of cases have been reported in wildlife (wild boars and badgers) and livestock (goat and cattle) in the frame of bovine tuberculosis (bTB) surveillance program, demonstrating the risk of interference with bTB diagnosis in France. In 2019, we detected four cattle infected with , from three different herds in three different distant regions.

Second line molecular diagnosis for bovine tuberculosis to improve diagnostic schemes.

Surveillance of bovine tuberculosis (bTB) is partly based on the sanitary inspection of carcasses at the abattoir to detect bTB-like lesions which, in compliance with EU recommendations, are analysed by bacteriology and histopathology to disclose Mycobacterium bovis (or M. caprae) infection. Moreover, since 2012, a PCR method with similar sensitivity and specificity values of histopathology and bacteriology respectively is additionally employed in France, partially compensating for the weaknesses of classical diagnostic methods.

Mycobacterium bovis Infection of Red Fox, France.

Mycobacterium bovis infection in wild red foxes was found in southern France, where livestock and other wildlife species are infected. Foxes frequently interact with cattle but have been underestimated as a reservoir of M. bovis.

Draft Genome Sequences of Three Strains Identified in Cattle and Wildlife in France.

is the etiologic agent of bovine tuberculosis, a chronic infectious disease affecting livestock, wild animals, and sometimes humans. We report here three draft genome sequences of strains of spoligotypes SB0821 and SB0134, isolated from wildlife but circulating in wildlife-livestock multihost systems, and SB0121, circulating exclusively in cattle.

Draft Genome Sequence of Mycobacterium bovis Strain D-10-02315 Isolated from Wild Boar.

Mycobacterium bovis is the etiologic agent of bovine tuberculosis, a chronic infectious disease, affecting livestock, wild animals, and sometimes humans. We report the draft genome sequence of a Mycobacterium bovis strain isolated from wild boar of spoligotype SB0120 (or BCG-like) also present in wildlife-livestock multi-host systems.

MIRU-VNTR allelic variability depends on Mycobacterium bovis clonal group identity.

The description of the population of M. bovis strains circulating in France from 1978 to 2013 has highlighted the discriminating power of the MLVA among predominant spoligotype groups. In the present study we aimed to characterize clonal groups via MLVA and to better understand the strain's population structure.

Genetic evolution of Mycobacterium bovis causing tuberculosis in livestock and wildlife in France since 1978.

To study the dynamics of bovine tuberculosis (bTB) in France, 4,654 M. bovis strains isolated mainly from livestock and wildlife since 1978 were characterized by spoligotyping and MLVA based on MIRU-VNTR. In our study spoligotyping allowed the discrimination of 176 types although 3 spoligotypes are predominant and account for more than half of the total strain population: SB0120 (26%), SB0134 (11%) and SB0121 (6%).

Infection with Mycobacterium microti in animals in France.

We describe here 35 animal cases of tuberculosis due to Mycobacterium microti in France (2002-2014). Recently, molecular tools that overcome the difficulty of confirming infection by this potentially zoonotic agent have revealed an increasing number of cases, suggesting that its prevalence may have been underestimated.

Estimation of sensitivity and specificity of bacteriology, histopathology and PCR for the confirmatory diagnosis of bovine tuberculosis using latent class analysis.

Bacteriology and histopathology are the most commonly used tests used for official confirmatory diagnosis of bovine tuberculosis (bTB) in cattle in most countries. PCR is also being used increasingly because it allows a fast diagnosis. This test could be applied as a supplement to or replacement for current bTB confirmatory diagnostic tests but its characteristics have first to be evaluated.

Real-time PCR for identification of Brucella spp.: a comparative study of IS711, bcsp31 and per target genes.

Culture is considered as the reference standard assay for diagnosis of Brucella spp. in humans and animals but it is time-consuming and hazardous. In this study, we evaluated the performances of newly designed real-time PCR assays using TaqMan probes and targeting the 3 following specific genes: (i) the insertion sequence IS711, (ii) bcsp31 and (iii) per genes for the detection of Brucella at genus level.
