Colonisation Dynamics

Abstract Background Staphylococcus aureus has been associated with the exacerbation and severity of atopic dermatitis (AD). Studies have not investigated the colonisation dynamics of S. aureus lineages in African toddlers with AD. We determined the prevalence and population structure of S. aureus in toddlers with and without AD from rural and urban South African settings. Methods We conducted a study of AD-affected and non-atopic AmaXhosa toddlers from rural Umtata and urban Cape Town, South Africa. S. aureus was screened from skin and nasal specimens using established microbiological methods and clonal lineages were determined by spa typing. Logistic regression analyses were employed to assess risk factors associated with S. aureus colonisation. Results S. aureus colonisation was higher in cases compared to controls independent of geographic location (54% vs. 13%, p < 0.001 and 70% vs. 35%, p = 0.005 in Umtata [rural] and Cape Town [urban], respectively). Severe AD was associated with higher colonisation compared with moderate AD (86% vs. 52%, p = 0.015) among urban cases. Having AD was associated with colonisation in both rural (odds ratio [OR] 7.54, 95% CI 2.92–19.47) and urban (OR 4.2, 95% CI 1.57–11.2) toddlers. In rural toddlers, living in an electrified house that uses gas (OR 4.08, 95% CI 1.59–10.44) or utilises kerosene and paraffin (OR 2.88, 95% CI 1.22–6.77) for heating and cooking were associated with increased S. aureus colonisation. However, exposure to farm animals (OR 0.3, 95% CI 0.11–0.83) as well as living in a house that uses wood and coal (OR 0.14, 95% CI 0.04–0.49) or outdoor fire (OR 0.31, 95% CI 0.13–0.73) were protective. Spa types t174 and t1476, and t272 and t1476 were dominant among urban and rural cases, respectively, but no main spa type was observed among controls, independent of geographic location. In urban cases, spa type t002 and t442 isolates were only identified in severe AD, t174 was more frequent in moderate AD, and t1476 in severe AD. Conclusion The strain genotype of S. aureus differed by AD phenotypes and rural-urban settings. Continued surveillance of colonising S. aureus lineages is key in understanding alterations in skin microbial composition associated with AD pathogenesis and exacerbation.

Colonisation Dynamics

Abstract Background: Staphylococcus aureus has been associated with the exacerbation and severity of atopic dermatitis (AD). Studies have not investigated the colonisation dynamics of S. aureus lineages in African children with AD. We determined the prevalence and population structure of S. aureus in children with and without AD from rural and urban South African settings. Methods: We conducted a study of AD-affected and non-atopic AmaXhosa children from rural Umtata and urban Cape Town, South Africa. S. aureus was screened from skin and nasal specimens using microbiological culture, and S. aureus clonal lineages were determined by spa typing. Logistic regression analyses were employed to assess risk factors associated with S. aureus colonisation. Results: S. aureus colonisation was higher in cases compared to controls (60% vs. 21%, p=0.000) and when stratified for location (54% vs. 13%, p=0.000 and 70% vs. 35%, p=0.005 in Umtata and Cape Town, respectively). Severe AD was associated with higher colonisation compared with moderate AD (86% vs. 52%, p=0.022) among urban cases. Having AD was associated with colonisation in both rural (odds ratio [OR] 7.54, 95% CI 2.92–19.47) and urban (OR 4.2, 95% CI 1.57–11.2) children. In rural children, living in an electrified house that also uses gas (OR 4.08, 95% CI 1.59–10.44) or in a house that uses kerosene and paraffin (OR 2.88, 95% CI 1.22–6.77) for heating and cooking were associated with increased S. aureus colonisation, while exposure to animals (OR 0.3, 95% CI 0.11–0.83) as well living in a house that uses wood and coal (OR 0.14, 95% CI 0.04–0.49) and an outdoor fire (OR 0.31, 95% CI 0.13–0.73) were protective. Among urban children, t272 and t1476 dominant among cases but no single spa type dominated among controls. In urban cases, spa types t002 and t442 isolates were only identified in severe AD and t174 was more frequent in moderate AD while t1476 in severe AD. Conclusion: The strain genotype of S. aureus differed by AD phenotypes and rural-urban living. Continued surveillance of colonising S. aureus lineages is key in understanding alterations in skin microbial composition associated with AD pathogenesis and exacerbation.

Indonesia has 20,000 types of plants where 300 species have been used as traditional medicines. The use of traditional medicine as an alternative treatment in Indonesia that has been used by both rural and urban communities. The use of traditional medicine is considered safer than modern medicine. The purpose of this study was to identify the level of use of traditional medicine and public awareness in the use of traditional medicine in work area of  Health Center Gombong 1 which consists of 5 villages. This research is a non-experimental and descriptive research that uses a questionnaire. Respondents who participated in this study were 140 people. The characteristics of respondents who participated in this study were the majority of men (50,71%), last educated of elementary school (41,43%), as housewives (27,86%). The majority of people in work area of Health Center Gombong choose treatment with modern medicine (64,29%). In addition there are 35,71% using traditional medicine and the majority use rhizome species (46%) for the treatment of minor ailments. In this study also showed that the majority of people do not know the safety of traditional medicines (50%) due to lack of information so that information is needed on the benefits and safety and the use of good and appropriate traditional medicines.

Diabetic foot infections (DFIs) are a significant health issue and a common complication among patients with diabetes. To develop antibiotic therapy for these high-risk patients, the current study evaluates the scope of DFIs and identifies the causing microbes. It also measures spectrum and antibiotic susceptibility of the pathogens isolated from adults with DFIs in Saudi Arabia. To achieve the study objectives, a cross-sectional study was implemented and the baseline characteristics for 44 patients with DFIs were defined. Optimal aerobic and anaerobic microbiological techniques were utilized to culture specimens isolated from infected foot ulcers. The standard microbiological methods were employed to identify the bacterial isolates and antibiotic susceptibility testing was conducted following the procedures of the Clinical and Laboratory Standards Institute (CLSI). Results showed that 12 microorganisms were isolated from the participants’ diabetic foot ulcers. Staphylococcus Aureus was ranked first because it appeared in 29 (65.9%) cases. Streptococcus Agalactiae was ranked second and multi-microbial infections were also found. Most of the organisms were susceptible to Vancomycin, Ciprofloxacin, and Cefalexin, but they were resistant to Methicillin, Gentamicin, and Ampicillin antibiotics. Staphylococcus Aureus was most sensitive to Ciprofloxacin, while it was resistant to Methicillin. About 10% of the isolates were multidrug-resistant. The study concludes that while Vancomycin should be used empirically for Gram-positive isolates, Ciprofloxacin can be taken into consideration for most of the Gram-negatives aerobes. Based on including various microorganisms and the advent of multidrug-resistant strains, proper culture and sensitivity testing are necessary prior to the empirical therapy.

Food And Nutritional Security

Solanum aethiopicum is a very important vegetable for both rural and urban communities in Africa. The crop is rich in both macro- and micronutrients compared with other vegetables and is suitable for ensuring food and nutritional security. It also possesses several medicinal properties and is currently employed in the treatment of high blood pressure, diabetes, cholera, uterine complaints as well as skin infections in humans. The crop is predominantly cultivated by traditional farmers and plays an important role in the subsistence and economy of poor farmers and consumers throughout the developing world. It also holds potential for dietary diversification, greater genetic biodiversity and sustainable production in Africa. Despite the numerous benefits the crop presents, it remains neglected and underutilized due to the world’s over-dependence on a few plant species, as well as the little attention in research and development it has received over the years. This review highlights the importance of S. aethiopicum, its role in crop diversification, reducing hidden hunger, the potential for nutritive and medicinal benefits, agricultural sustainability and future thrusts for breeding and genetic improvement of the plant species.
