Exploring the cellulolytic activity of environmental mycobacteria.

Although studies on non-tuberculous mycobacteria have increased in recent years because they cause a considerable proportion of infections, their cellulolytic system is still poorly studied. This study presents a characterization of the cellulolytic activities of environmental mycobacterial isolates derived from soil and water samples from the central region of Argentina, aimed to evaluate the conservation of the mechanism for the degradation of cellulose in this group of bacteria. The molecular and genomic identification revealed identity with Mycolicibacterium septicum.

Bovine campylobacteriosis in heifer: pathogenesis study and insights in the conventional and molecular diagnosis in an experimental bovine model and field cases.

Campylobacter fetus spp. is a bacterium associated to reproductive losses in cattle worldwide. It is a venereal infectious disease known as bovine campilobacteriosis, with high impact mainly in countries with extensive production systems.

Bovine campylobacteriosis in bulls: insights in the conventional and molecular diagnosis.

Campylobacter fetus is a gram-negative motile bacterium, with two subspecies relevant to cattle health: C. fetus subsp. venerealis (Cfv) and C.

Phylogenetic and Multiple-Locus Variable number tandem repeat analysis of Mycobacterium avium subsp. paratuberculosis isolates from Argentina.

Paratuberculosis is a worldwide chronic enteric disease of ruminants, caused by Mycobacterium avium subsp. paratuberculosis (MAP). While MAP has been widely investigated all around the world, little is known about the different strains that circulate in each country.

Campylobacter fetus releases S-layered and immunoreactive outer membrane vesicles.

The study of outer membrane vesicles (OMVs) became relevant because of their probable important role in the transfer of virulence factors to host cells. Campylobacter fetus is mainly a mammal pathogen whose virulence characterization is still limited. The aim of this study was to evaluate and to characterize the secretion of OMVs in this bacterium.

Phylogenomic analysis for ocurring in Argentina.

Background And Aim: is one of the most important pathogens that severely affects livestock industry worldwide. mediated bovine genital campylobacteriosis infection in cattle has been associated with significant economic losses in livestock production in the Pampas region, the most productive area of Argentina. The present study aimed to establish the genomic relationships between strains, isolated from the Pampas region, at local and global levels.

L-cysteine transporter-PCR to detect hydrogen sulfide-producing .

Phenotypic differences between and subspecies allow the differential diagnosis of bovine genital campylobacteriosis. The hydrogen sulfide production, for example, is a trait exclusive to and biovar intermedius. This gas that can be biochemically tested can be produced from L-cysteine (L-Cys).
