The effects of irrigation on the survival of in the phyllosphere and soil environments of lettuce.

Unlabelled: This study aimed to address the gap in knowledge regarding the fate of foodborne pathogens within agro-ecosystems. It specifically focused on the surrogate microorganism , which was introduced into lettuce-producing environments via surface and spray irrigation methods, respectively. The concentration of in the rhizosphere, phyllosphere, and non-rhizosphere soil was quantified by quantitative polymerase chain reaction (qPCR) over a 42-day trial.

The phylogenomic landscape of extended-spectrum β-lactamase producing Citrobacter species isolated from surface water.

Background: Citrobacter species are Gram-negative opportunistic pathogens commonly reported in nosocomial-acquired infections. This study characterised four Citrobacter species that were isolated from surface water in the North West Province, South Africa.

Results: Phenotypic antimicrobial susceptibility profiles of the isolates demonstrated their ability to produce the extended-spectrum β-lactamase (ESBL).

Genetic diversity and whole genome sequence analysis data of multidrug resistant atypical enteropathogenic Escherichia coli O177 strains: An assessment of food safety and public health implications.

Atypical enteropathogenic E. coli (aEPEC) strains are emerging pathogens responsible for fatal diarrhoea in humans worldwide. The purpose of this study was to investigate genetic diversity, virulence and antimicrobial resistance profiles of aEPEC O177 strains isolated from faeces of cattle reared in intensive and extensive production systems in South Africa.

Screening of Rhizosphere Bacteria and Nematode Populations Associated with Soybean Roots in the Mpumalanga Highveld of South Africa.

Soybean is among South Africa's top crops in terms of production figures. Over the past few years there has been increasingly more damage caused to local soybean by plant-parasitic nematode infections. The presence of (root-knot nematodes) and spp.

Wastewater treatment works change the intestinal microbiomes of insectivorous bats.

Mammals, born with a near-sterile intestinal tract, are inoculated with their mothers' microbiome during birth. Thereafter, extrinsic and intrinsic factors shape their intestinal microbe assemblage. Wastewater treatment works (WWTW), sites synonymous with pollutants and pathogens, receive influent from domestic, agricultural and industrial sources.
