Phytases (myo-inositol hexakisphosphate phosphohydrolases) hydrolyze the phosphate ester bonds of phytate-releasing phosphate and lower myo-inositol phosphates and/or myo-inositol. Phytases, in general, are known to enhance phosphate and mineral uptake in monogastric animals such as poultry, swine, and fish, which cannot metabolize phytate besides reducing(More)
In South Africa, a large proportion of young women are in age disparate relationships, which is believed to be a risk factor for human immunodeficiency virus (HIV). The aim of this study was to determine the generational effect of age disparity on HIV and sexually transmitted infection (STI) incidence. Socio-demographic and behavioural data were collected(More)
SETTING In KwaZulu-Natal, South Africa, a setting endemic for tuberculosis (TB) and the human immunodeficiency virus (HIV), prolonged hospitalisation for the treatment of the growing number of multidrug-resistant TB (MDR-TB) patients is neither possible nor effective. OBJECTIVE To compare early treatment outcomes in patients with MDR-TB with and without(More)
The association between bacterial vaginosis (BV) and incident sexually transmitted infections (STIs) in a cohort of high-risk women from Durban, South Africa was investigated in this study. We undertook a secondary analysis of the Methods for Improving Reproductive Health in Africa trial that assessed effectiveness of the latex diaphragm and lubricant gel(More)
BACKGROUND Couples' voluntary HIV counseling and testing (CVCT) is an evidence-based intervention that significantly reduces HIV incidence in couples. Despite the high prevalence of HIV and HIV couple serodiscordance in South Africa, there are few CVCT services. METHODS From February-June 2013, The Rwanda Zambia HIV Research Group provided support,(More)
Background. To the best of our knowledge, there have been no published reports on the diagnostic performance of the Chlamydia Rapid Test (CRT) Device for male urine samples. We evaluated the performance of the CRT Device when compared with that of the BD ProbeTec ET PCR Assay in a population of asymptomatic men. Methods. The study enrolled 100 men between(More)
Nef plays a major role in HIV-1 pathogenicity. We studied HIV-1 subtype C infected individuals in acute/early (n = 120) or chronic (n = 207) infection to investigate the relationship between Nef-mediated CD4/HLA-I down-regulation activities and disease progression, and the influence of immune-driven sequence variation on these Nef functions. A single Nef(More)
BACKGROUND Nosocomial transmission has been implicated as a key factor in the outbreak of extensively drug resistant (XDR) and multidrug-resistant (MDR-TB) tuberculosis at Church of Scotland Hospital (CoSH), in KwaZulu-Natal (KZN), South Africa. The aim of this study was to quantify the burden of potentially infectious tuberculosis and the proportion of(More)
OBJECTIVE Couples' voluntary HIV counseling and testing (CVCT) significantly decreases HIV transmission within couples, the largest risk group in sub-Saharan Africa, but it is not currently offered in most HIV testing facilities. To roll out such an intervention, understanding locale-specific knowledge barriers is critical. In this study, we measured(More)
We evaluated a point-of-care test for the detection of Neisseria gonorrhoeae in patients attending a public health clinic in KwaZulu-Natal, South Africa. The test showed a low sensitivity against PCR and culture (<40%); however, a higher specificity was observed (>95%). This test is unsuitable as a screening tool for gonorrhea.
