Purification and molecular characterization of chitinases from soil actinomycetes

Microbial extracellular chitinases are used in agriculture as effective biocontrol agents and in waste degradation, pharmaceutical and food industry. Actinomycetes are widely tapped group for production of extracellular chitinases. In the present study, approximately 260 actinomycetes were isolated from various ecological habitats was subjected to primary analyses and screened for production of chitinase by plate assay...

Improvement of decontamination and isolation protocols for Mycobacterium avium subspecies paratuberculosis (MAP) from raw milk samples

Most protocols regarding sample decontamination for Mycobacterium avium subspecies paratuberculosis (MAP) isolation are based on the MAP detection from feces and not milk. The choice of the best decontamination protocol is crucial to a successful MAP isolation. In this study, 36 combinations of variables for sample decontamination and MAP isolation from raw milk presented in the literature were carried out on milk...

Biological control of potential antagonistic bacteria isolates to restrict Magnaporthe grisea infection on rice

Rice blast caused by Magnaporthe grisea, frequently affects rice in the world. This research is intended to screen biological control agents for controlling M. grisea, referencing the study biological control agents testing approaches, since biological control is an environmentally friendly plant disease controlling approach. 710 bacterial isolates were discovered from rice tissues, of which hopeful biological control...

Prevalence and resistance profile of extended-spectrum β-lactamases-producing Enterobacteriaceae in Ouagadougou, Burkina Faso

Increasing bacterial resistance to antimicrobial agents has become an issue of concern. A major problem of the treatment of infections caused by Enterobacteriaceae using antibiotics is the emergence of Extended-spectrum β-lactamases (ESBL)-producing Enterobacteriaceae. This study aims to determine the prevalence of ESBL-producing Enterobacteriaceae strains in Ouagadougou, Burkina Faso, and describe their resistance...
