Molecular epidemiology of antibiotic-resistant enterococcus spp. from farm to food-production chain in intensive poultry production in KwaZulu-Natal, South Africa.
(2019)Extensive antibiotic use in intensively-farmed poultry exerts selection pressure for the emergence of multidrug-resistant pathogens. The aim of this study was to determine the antibiotic resistance and virulence profiles ... -
A descriptive analysis of the routine use of genotype MTBDRsl in a high HIV/TB prevalent region in South Africa.
(2020)Background. Since the implementation of shortened drug regimens for the management of drug resistant tuberculosis (TB), there is a growing need for rapid detection of resistance to second line antimycobacterial drugs. The ... -
The effect of HIV and Neisseria gonorrhoeae on the tight junctions of cervical epithelial cells.
(2020)Introduction: Neisseria gonorrhoeae and HIV are major public health concerns globally. The interaction between these diseases is unclear. To determine the effect that N. gonorrhoeae and HIV have on the tight junctions of ... -
The impact of the introduction of direct first and second-line reflex testing in the management of drug-resistant Tuberculosis at Greytown Hospital, Umzinyathi District, KwaZulu-Natal.
(2020)Background Drug resistant tuberculosis (DR-TB) is a serious public health issue both globally and nationally, with South Africa and Kwazulu-Natal, in particular, being among the regions with the highest burden of DR-TB. ... -
Lung tissue resident memory T and B cells in the immune response to Mycobacterium tuberculosis in humans.
(2019)Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb) is the main cause of death from a single infectious agent. Although a quarter of the world population is estimated to be infected with TB, only 5–10% of these ... -
Mycobacterium tuberculosis pili (MTP) modulates pathogen and host metabolomic changes in an A549 epithelial cell model of infection.
(2020)Background/Aim: Mycobacterium tuberculosis, the causative organism of tuberculosis, continues to drive research efforts in the quest to develop novel diagnostics and therapeutics. The complexities associated with drug-resistant ... -
Transepithelial migration of Mycobacterium tuberculosis strains and their affinity for glial cells in vitro.
(2019)Background: Tuberculosis is an infectious disease caused by the bacillus M. tuberculosis. It is a disease that mainly infects the lungs, however, almost any other organ of the body can be infected. Central nervous system ... -
The interaction between nutrition, immunity and coinfections with human immunodeficiency virus and intestinal parasites in South African adults: investigating the use of prealbumin as a tool for nutritional assessment.
(2019)Highly prevalent HIV and helminth single infections continue to plague a significant proportion of the South African population. The geographic overlap of these infections lands to the expectation that high prevalence of ... -
Systemic lymphocyte trafficking markers in TB and TB/HIV co-infections.
(2019)Background. Several studies demonstrate that immune inflammation and trafficking of immune cells to affected tissues plays a major role in the pathogenesis of tuberculosis (TB) and human immunodeficiency virus (HIV) ... -
Effect of the capsular material of cryptococcus neoformans on the interplay between Mmicroglial cells and Neutrophils.
(2019)Cryptococcal meningitis is an important opportunistic infection in immunocompromised patients. It has been well established that a distinguishing feature of this form of meningitis is a relatively low neutrophil count in ... -
Investigations into the morphometrics, uterine tissue adaptation, maternal fluid biochemistry, heavy metal offloading and early embryonic teeth development impacting the reproductive strategy of the female Ragged-tooth shark (Carcharias taurus)
(2018)Vulnerable” status of ragged-tooth sharks (Carcharias taurus) in South Africa caused by overexploitation, late maturity and low fecundity suggests an intervention to increase the size of this population is needed. Achieving ... -
The cytotoxic effects of fumonisin B1 in human kidney cells and the ability of allicin to ameliorate these effects.
(2019)Fumonisin B1 (FB1) is a widespread contaminant of crops and is produced as a secondary metabolite of fungi. It has been found to disrupt sphingolipid metabolism, cause epigenetic modifications and induce cellular toxicity ... -
Methyl picolinic acid plays a role in epigenetic modifications in Human HepG2 liver cells.
(2019)Picolinic Acid (PA) is an endogenous catabolite synthesized from L-Tryptophan via the kynurenine pathway. PA has been reported to possess immunological, neuroprotective, and anti-proliferative properties; however, its most ... -
In vitro effects of intravaginal insertion products (IVIPs) on biomarkers of inflammation and immune cellular activation in the era of HIV.
(2019)The use of vaginal products is associated with increased HIV acquisition risk, but the mechanism is not fully understood. Vaginal practices entail the use of a wide variety of products which can alter the vaginal environment ... -
Metformin alleviates neuronal and renal related stress signals in diabetic C57BL/6 mice.
(2019)In recent years, diabetes has become more prevalent due to modern, demanding, and sedentary lifestyle patterns. This disease is characterised by insulin resistance and associated molecular complications. Metformin (MF) is ... -
Aflatoxin B1 modulates oxidative stress and apoptosis in human embryonic kidney cells.
(2019)Introduction: Aflatoxin B1 (AFB1) is produced by filamentous fungal strains of Aspergillus flavus and Aspergillus parasiticus that infect field crops, therefore AFB1 is a frequent contaminant of dietary staples such as ... -
The development of a stratified keratinocyte model for chlamydia trachomatis pathogenesis studies.
(2017)A number of different methods to generate stratified keratinocyte layers have been published. These involved the use of normal human epidermal keratinocytes (NHEKs/NEKS), which have a better ability to stratify compared ... -
Cytokine production by ME-180 cells and VK2 E6/E7 cells on exposure to Neisseria gonorrhoeae, HIV, N. gonorrhoeae and HIV.
(2018)Gonorrhoea is a sexually transmitted disease caused by Neisseria gonorrhoeae. Women are more at risk in developing secondary complications due to asymptomatic infections. In 2001, a study was done on the different responses ... -
