Metabolic interactions of Limosilactobacillus reuteri ZJ625 and Ligilactobacillus salivarius ZJ614 in co-culture: implications for multi-strain probiotics.

Aims: Limosilactobacillus reuteri ZJ625 and Ligilactobacillus salivarius ZJ614 are potential probiotic bacteria. The mechanisms of enhanced benefits by muti-strain probiotics are yet fully understood. We elucidated the influence of co-culturing on the metabolite profiles of Limosilactobacillus reuteri ZJ625 and Ligilactobacillus salivarius ZJ614 to decipher the impacts of co-culturing on metabolic interactions between the strains.

'Multi-omics' data integration: applications in probiotics studies.

The concept of probiotics is witnessing increasing attention due to its benefits in influencing the host microbiome and the modulation of host immunity through the strengthening of the gut barrier and stimulation of antibodies. These benefits, combined with the need for improved nutraceuticals, have resulted in the extensive characterization of probiotics leading to an outburst of data generated using several 'omics' technologies. The recent development in system biology approaches to microbial science is paving the way for integrating data generated from different omics techniques for understanding the flow of molecular information from one 'omics' level to the other with clear information on regulatory features and phenotypes.

Antimicrobial resistance pattern of methicillin-resistant isolated from sheep and humans in Veterinary Hospital Maiduguri, Nigeria.

Background And Aim: Methicillin-resistant (MRSA), an important opportunistic pathogen, is a Gram-positive coccus known to be resistant to β-lactam antibiotics. Its virulence depends on a large range of factors, mainly extracellular proteins, such as enzymes and exotoxins, that contribute to causing a wide range of diseases in human and animal species. The major reasons for the success of this pathogen are its great variability, which enables it to occur and thrive at different periods and places with diverse clonal types and antibiotic resistance patterns within regions and countries.

Multi-Strain Probiotics: Synergy among Isolates Enhances Biological Activities.

The use of probiotics for health benefits is becoming popular because of the quest for safer products with protective and therapeutic effects against diseases and infectious agents. The emergence and spread of antimicrobial resistance among pathogens had prompted restrictions over the non-therapeutic use of antibiotics for prophylaxis and growth promotion, especially in animal husbandry. While single-strain probiotics are beneficial to health, multi-strain probiotics might be more helpful because of synergy and additive effects among the individual isolates.

Phenotypic detection of methicillin-resistant aureus in village chickens from poultry markets in Maiduguri, Nigeria.

Objective: The study was carried out to detect the carriage of methicillin-resistant (MRSA) and their antimicrobial susceptibilities in village chickens sold at Maiduguri poultry markets using phenotypic characterization.

Materials And Methods: This was a cross-sectional study where 120 samples comprised 50% each of Nasal and cloacal swabs, were, respectively, collected from live village chickens sold at Maiduguri poultry markets and examined for the presence MRSA based on bacterial culture, biochemical characteristics, growth on oxacillin resistant screening agar base, and antimicrobial susceptibility tests.

Results: The study revealed an overall occurrence of 38.
