Autolytic characterization of selected Enterococcal strains, (previously Streptococcal)
(2007)Autolysins are enzymes that cleave specific structural components within the bacterial cell wall. They contribute to numerous cellular activities such as cell growth, cell division, peptidoglycan recycling and turnover. ... -
Behavioural, reproductive and growth studies on Oreochromis mossambicus (Peters 1852)
(2010)A major obstacle facing the successful creation of an African aquaculture industry, based upon Oreochromids, is the irregular supply of good quality fish seed. There are several causative biological processes behind its ... -
Breed effects on the virulence gene profiles and genetic diversity at FUT1, MUC4, MUC13 and MUC20 candidate genes for controlling diarrhoea-causing Escherichia coli.
(2013)Escherichia (E) coli infections result in diarrhoea and oedema in growing pigs. Enterotoxigenic (ETEC), shigatoxin producing (STEC) and enteroaggregative (EAEC) E. coli have been identified as the principal causes of ... -
Breeding of advanced generation of Eucalyptus macarthurii-growth parameters and development of a near infrared (NIR) calibration model to predict whole tree pulp yield using non destructive cores.
(2008)Eucalyptus macarthurii is one of the cold tolerant eucalypt species grown in South Africa for pulp and paper. However, little research has been done on this species’ growth performance. A study was therefore initiated ... -
Characterisation of antibiotic resistance in Streptococcus, Enterococcus and Staphylococcus using a bioinformatics approach.
(2005)The rate at which bacterial pathogens are becoming resistant to antibiotics is quite alarming, and therefore much attention has been focussed on this area. The mechanism whereby the bacterial cells acquire resistance is ... -
Characterisation of the divergence of the Elsenburg Merino resource flock.
(2012)The Elsenburg Merino flock has been divergently selected for the ability of ewes to rear multiple offspring since 1986. Updated genetic trends for reproduction are reported for the Elsenburg Merino resource flock. The ... -
Characterization of streptococcal infections in KwaZulu-Natal Durban by random amplified polymorphic DNA anaylsis and DNA macrorestriction analysis.
(2004)A collection of 29 clinical streptococcal isolates obtained from the University of KwaZulu-Natal, Medical School, Durban Metro area (South Africa) were studied to establish their penicillin G susceptibility patterns often ... -
Characterization of the autolytic systems in selected streptococcal species.
(2005)Autolysins are endogenous enzymes responsible for the cleavage of specific bonds in the bacterial sacculus resulting in damage to the integrity and protective properties of the cell wall. The true biological functions of ... -
Cloning, expression and purification of the immunity factor associated with leucocin A production.
(2004)Leucocin A is a bacteriocin produced by Leucoconostoc gelidium UAL 187-22. Bacteriocin producer strains possess an immunity protein, which enables the strain to protect itself against its own bacteriocin. The immunity ... -
Cloning, expression and purification of the subunits of the Mannose PTS Permease of Listeria monocytogenes EGD.
(2010)The disease listeriosis is caused by Listeria monocytogenes. This common food-borne disease has been responsible for about 0.1 to 10 cases per million inhabitants per year. However, this disease is serious with its high ... -
Computer simulation of marker-assisted selection utilizing linkage disequilibrium.
(2006)The face of animal breeding has changed significantly over the past few decades. Traditionally, the genetic improvement of both plant and animal species focussed on the selective breeding of individuals with superior ... -
Direct transformation of maize (Zea mays L.) tissue using electroporation and particle bombardment, and regeneration of plantlets.
(1996)Please open electronic version for Abstract. -
Dynamics of the glutathione/glutaredoxin system.
(2014)The glutathione/glutaredoxin system is made up of glutaredoxins, glutathione (GSH) and glutathione reductase (GLR). Glutaredoxins, which are involved in essential cellular functions such as DNA synthesis, iron metabolism ... -
The dynamics of thioredoxin-dependent reactions.
(2014)The thioredoxin system, comprising thioredoxin (Trx), thioredoxin reductase (TrxR) and NADPH, is present in most organisms from prokaryotes to eukaryotes. The system plays a central role in the redox regulation of several ... -
The effect of genotype on avian malaria infections in the Amur falcon (Falco amurensis)
(2022)Avian malaria is caused by haemosporidian parasites (Plasmodium, Haemoproteus and Leucocytozoon) that are transmitted by dipteran vectors. Passerines have been the focus of avian malaria research however raptors are generally ... -
Elucidation of gene function using RNA interference in a cancer cell culture model.
(2011)RNA interference (RNAi), mediated by small interfering RNA (siRNA), has emerged as a powerful tool for elucidating gene function and also holds great potential for the treatment of acquired and inherited diseases. The ... -
The elucidation of the possible mechanism of vancomycin-resistance in selected streptococcal and enterococcal species.
(2005)Three Streptococcal strains: S. milleri P213, S. milleri P35 and S. milleri B200 and three enterococcal strains: E. faecalis 123, E. faecalis 126 and E. faecium were used to test for vancomycin resistance. Two strains were ... -
Estimation of genetic and demographic parameters of extensively raised chicken populations using genome-wide single nucleotides polymorphism (SNP) data.
(2015)Village chicken populations are raised under a farming system that faces a number of challenges such as small flock size, lack of animal performance and pedigree records, lack of proper husbandry and poorly defined and ... -
Estimation of genetic variation and marker identification in black wattle (Acacia mearnsii De Wild) with RAPD fingerprinting.
