A Review of Medicinal Plants Used in the Management of Microbial Infections in Angola.

The use of medicinal plants in the management of microbial infections is significant to the health of the indigenous people in many Angolan communities. The present study provides a comprehensive overview of medicinal plants used for the management of microbial infections in Angola. Relevant information was extracted from research articles published and associated with the use of medicinal plants in the management of microbial infections in Angola (from January 1976 to November 2023).

Evaluation of organochlorine pesticide residues in , , and in Bloemfontein markets, South Africa.

This study evaluated the level of selected pesticide residues in the staple vegetables;   .  (cabbage), .  (Swiss chard), and   (potato) from fresh produce markets in the city of Bloemfontein, South Africa.

Interspecific competition in germination of bird-dispersed seeds in a habitat with sparse tree vegetation in South Africa.

Background: By transporting and scarifying the seeds during ingestion, avian frugivores reduce the competition with siblings, and may improve the germination which is critical for dispersal effectiveness and population recruitment. However, generally, there is limited knowledge on how deposited seeds interact/compete in the new microsite. We tested the hypothesis that the bird-dispersed seeds benefit from improved germination after their passage through the bird's gut; and we investigated the potential impact of seed density on competition at the microsites by determining whether seed density and species diversity influence germination in the Free State Province, South Africa.

Chemical Contamination Pathways and the Food Safety Implications along the Various Stages of Food Production: A Review.

Historically, chemicals exceeding maximum allowable exposure levels have been disastrous to underdeveloped countries. The global food industry is primarily affected by toxic chemical substances because of natural and anthropogenic factors. Food safety is therefore threatened due to contamination by chemicals throughout the various stages of food production.

Microbial levels on street foods and food preparation surfaces in Mangaung Metropolitan Municipality.

Background: The street food sector has become an important component of the food distribution system in many cities in both developing and industrialised countries, particularly for midday meals. However, certain street food can pose a significant risk to consumers because of microbiological contamination.

Aim: The aim of this study was to determine the microbial levels of street foods and preparation surfaces in Mangaung Metropolitan Municipality.

Disruption of microbial cell morphology by Buxus macowanii.

Background: Microbial infections are one of the major causes of death globally. This is attributed to the rising costs of primary healthcare and its inaccessibility especially in developing countries. Moreover, there has been an increase in microbial strains that have reduced susceptibility to antimicrobial drugs.

Identification of airborne microbiota in selected areas in a health-care setting in South Africa.

Background: The role of bio-aerosols in the spread of disease and spoilage of food has been described in numerous studies; nevertheless this information at South African hospitals is limited. Attributable to their size, bio-aerosols may be suspended in the air for long periods placing patients at risk of infection and possibly settling on surfaces resulting in food contamination. The aim of the study is to assess the microbial composition of the air in the kitchen and selected wards at a typical district hospital in South Africa.
