Draft genome sequence of a rare pigmented mycobacterium avium subsp. paratuberculosis type C strain

Mycobacterium avium subsp. paratuberculosis is the causative agent of paratuberculosis. We report here the draft genome sequence of a rare pigmented M. avium subsp. paratuberculosis type C strain, comprising 58 contigs and having a genome size of 4,851,414 bp. The genome will assist in the execution of pigmentation and virulence studies on this mycobacterium.

Enhanced Detection of Tuberculous Mycobacteria in Animal Tissues Using a Semi-Nested Probe-Based Real-Time PCR

Bovine tuberculosis has been tackled for decades by costly eradication programs in most developed countries, involving the laboratory testing of tissue samples from allegedly infected animals for detection of Mycobacterium tuberculosis complex (MTC) members, namely Mycobacterium bovis. Definitive diagnosis is usually achieved by bacteriological culture, which may take up to 6–12 weeks, during which the suspect animal carcass and herd are under sanitary arrest.

Detection of Theileria and Babesia infections amongst asymptomatic cattle in Portugal

Piroplasmosis caused by tick-borne hemoprotozoans of several Theileria and Babesia species has a major impact on livestock production worldwide. A reverse line blotting assay that includes genus- and species-specific probes for Theileria and Babesia species was used to assess the occurrence of these parasites in blood samples collected from 1407 healthy bovines throughout mainland Portugal.

Relatedness of Mycobacterium avium subspecies hominissuis clinical isolates of human and porcine origins assessed by MLVA

In this study, the analysis of Mycobacterium avium tandem repeats (MATRs) loci was adapted to evaluate the genetic diversity of epidemiological unrelated MAH clinical strains of human (n=28) and porcine (n=69) origins, collected from diverse geographical regions across mainland Portugal. These MAH isolates were found to be genetically diverse and genotypes are randomly distributed across the country.

Rapid identification of veterinary-relevant Mycobacterium tuberculosis complex species using 16S rDNA, IS6110 and Regions of Difference-targeted dual-labelled hydrolysis probes

In this work we describe a rapid and robust two-step five-target probe-based real-time PCR identification algorithm, based on genomic deletion analysis, to identify the MTC species most commonly associated with TB in livestock and other animals.
