Molecular evidence of Plasmodium vivax infection in Duffy negative symptomatic individuals from Dschang, West Cameroon.

Background: Plasmodium vivax infection is known to be rare in West/Central Africa, the most accepted explanation being the lack of expression of erythroid Duffy antigen in the local human populations. Duffy negativity prevents the parasite to exploit the entry mechanism on the red blood cell surface. However, there are a growing number of reported vivax infections in Duffy-negative individuals.

Nutrition Habits and Health Outcomes of Breastfeeding HIV-positive mothers in the Dschang Health District, West Region Cameroon.

Background: Amongst the different at-risk periods for mother-to-child HIV transmission that is, during pregnancy, labor and delivery and breastfeeding, much care and attention needs to be given, not only to the child as concerns its feeding options, but also to the mother. The aim of this study was to determine the nutritional habits and health outcomes of HIV-positive breastfeeding mothers in the Dschang Health District, in the context of prevention of mother-to-child transmission (PMTCT) activities.

Methods: A cross-sectional study was carried out from September 2014 to February 2015, at the Dschang District Day Care Hospital.

Poor Acceptability of Female Condom by Young Cameroonians: an Unmet Programmatic Agenda for HIV Prevention.

Background: An important component of the response to the AIDS epidemic is the prevention of HIV infection and other sexually transmitted diseases through the use of condoms. In order to enhance HIV prevention programs and minimize the occurrence of unwanted pregnancies, female condoms have been introduced within the community, with the ultimate goal of reducing vulnerability of women. The success of such a program depends on its acceptance by the target population.

MicroRNA from Moringa oleifera: Identification by High Throughput Sequencing and Their Potential Contribution to Plant Medicinal Value.

Moringa oleifera is a widespread plant with substantial nutritional and medicinal value. We postulated that microRNAs (miRNAs), which are endogenous, noncoding small RNAs regulating gene expression at the post-transcriptional level, might contribute to the medicinal properties of plants of this species after ingestion into human body, regulating human gene expression. However, the knowledge is scarce about miRNA in Moringa.

Field Application of the Micro Biological Survey Method for a Simple and Effective Assessment of the Microbiological Quality of Water Sources in Developing Countries.

According to the World Health Organization (WHO) guidelines, "safe drinking-water must not represent any significant risk to health over a lifetime of consumption, including different sensitivities that may occur between life stages". Traditional methods of water analysis are usually complex, time consuming and require an appropriately equipped laboratory, specialized personnel and expensive instrumentation. The aim of this work was to apply an alternative method, the Micro Biological Survey (MBS), to analyse for contaminants in drinking water.

CYP2B6 poor metaboliser alleles involved in efavirenz and nevirapine metabolism: CYP2B6*9 and CYP2B6*18 distribution in HIV-exposed subjects from Dschang, Western Cameroon.

The prescription of patients' tailored anti-infectious treatments is the ultimate goal of pharmacogenetics/genomics applied to antimicrobial treatments, providing a basis for personalized medicine. Despite the efforts to screen Africans for alleles underlying defective metabolism for a panel of different drugs, still more research is necessary to clarify the interplay between host genetic variation and treatments' response. HIV is a major infectious disease in sub-Saharan African countries, and the main prescribed anti-HIV combination therapy includes efavirenz (EFV) or nevirapine (NVP).
