Oceanic variability in the western sector of Algoa Bay, South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: EH Schumann JRS Churchill HJ ZaaymanThe city of Port Elizabeth lies in the western sector of Algoa Bay, and a number of projects have investigated the oceanic temperature, salinity and current structures in the vicinity. This paper analyses past results, and then incorporates measurements of... -
Algicidal bacteria isolated from the surface of seaweeds from the coast of Osaka Bay in the Seto Inland Sea, Japan
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: I Imai D Fujimaru T Nishigaki M Kurosaki H SugitaAlgicidal bacteria offer a promising tool for the prevention of red tides, because they are able to play a key role in terminating blooms in coastal areas. This study details the detection of vast numbers of algicidal bacteria attached to... -
Overgrazing of edible algae as a mechanism behind red tides and harmful algal blooms
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: T Johannessen E Dahl O LindahlIt has recently been suggested that there is a positive synergistic relationship between herbivorous zooplankton and their algal food, with herbivores stimulating the production of their preferred species while negatively affecting competing algal species. A prerequisite for this positive interaction... -
Meso-zooplankton movement through the newly constructed Mfolozi channel into and out of the St Lucia Estuary, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Sean van Elden --- School of Life Sciences, University of KwaZulu-Natal, Westville Campus, South Africa Michael J. Dyer --- School of Life Sciences, University of KwaZulu-Natal, Westville Campus, South Africa Nicola K. Carrasco --- School of Life Sciences, University of KwaZulu-Natal, Westville Campus, South Africa Renzo Perissinotto --- School of Life Sciences, University of KwaZulu-Natal, Westville Campus, South AfricaThe historical canalization of the Mfolozi River resulted in the St Lucia Estuary losing its main freshwater source. This, combined with the recent drought, led to low water levels, hypersaline conditions and dramatic losses in biodiversity. The excavation of a... -
Preoperative B-type natriuretic peptides in patients undergoing noncardiac surgery: a cumulative meta-analysis
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: Lisa Ryan --- Perioperative Research Group, Department of Anaesthetics, Grey’s Hospital, Nelson R. Mandela School of Medicine,, South Africa Chantal Rajah --- Perioperative Research Group, Department of Anaesthetics, Grey’s Hospital, Nelson R. Mandela School of Medicine,, South Africa Dale Simmers --- Department of Anaesthetics, Nelson R. Mandela School of Medicine, South Africa Danielle Potgieter --- Department of Anaesthetics, Nelson R. Mandela School of Medicine, South Africa Reitze N. Rodseth --- Perioperative Research Group, Department of Anaesthetics, Grey’s Hospital, Nelson R. Mandela School of Medicine,, South AfricaBackground: A plethora of studies have shown elevated preoperative natriuretic peptide measurements to predict postoperative mortality and adverse cardiac events.Objectives: The current study aimed to demonstrate this overwhelming association and to show that further studies of this nature are unwarranted.Methods:... -
Vancomycin versus teicoplanin in the treatment of serious Gram-positive infections: what do the minimum inhibitory concentration data tell us?
Item type: Journal Article • Journal: Southern African Journal of Infectious Diseases • Authors: W. Lowman --- Clinical Microbiology and Infectious Diseases, Wits School of Pathology, Faculty of Health Sciences,Glycopeptides are the mainstay of treatment against serious drug-resistant Gram-positive infections. The two principal agents are vancomycin and teicoplanin. Optimal dosing of both these antimicrobial agents, in terms of clinical outcomes and achievement of pharmacodynamic targets, has been shown to... -
First detected isolate of glycopeptide-intermediate resistant Staphylococcus aureus in a renal unit at a central academic hospital in Kwazulu-Natal
Item type: Journal Article • Journal: Southern African Journal of Epidemiology and Infection • Authors: K SweSwe-Han --- Department of Medical Microbiology, N Naidoo --- Department of Medical Microbiology, P Mahabeer --- Department of Medical Microbiology, K Mlisana --- Department of Medical Microbiology,Staphylococcus aureus is an important and common cause of healthcare and community-associated infections. Reduced susceptibility to glycopeptides in methicillin-resistant S. aureus is well documented. We report on the frst glycopeptide-intermediate S. aureus (GISA) isolate from a renal unit at a... -

Monaheng --- Department of Paediatrics, South Africa P. Roux --- School of Child and Adolescent Health, South Africa E. Haschke-Becher --- Central Laboratory, Department of Neurology, AustriaObjectives: The objectives of this study were to evaluate whether infants born to known HIV-positive mothers, but who were not themselves infected with HIV and who were fed a chemically acidified starter formula with prebiotics with or without nucleotides during... -
Intertidal mangrove boundary zones as nursery grounds for the mud crab Scylla serrata
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: DO Mirera --- Kenya Marine and Fisheries Research Institute (KMFRI), KenyaThe demand for mud crab Scylla serrata (Forsskål 1775) in the global market has increased, hence there is growing momentum to farm the species in Africa. Aquaculture production in Kenya and elsewhere in East Africa currently relies on juvenile seeds... -
Species boundaries and biogeography of East African torrent frogs of the genus Petropedetes (Amphibia: Anura: Petropeditidae)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: SimonP. Loader --- University of Basel, Switzerland F. Sara Ceccarelli --- University of Basel, Switzerland Mark Wilkinson --- The Natural History Museum, UK Michele Menegon --- Museo Tridentino di Scienze Naturali, Italy Jean Mariaux --- Muséum d'Histoire Naturelle, Switzerland RafaelO. de Sá --- University of Richmond, USA KimM. Howell --- University of Dar es Salaam, Tanzania DavidJ. Gower --- The Natural History Museum, UKBased on morphology there are currently three described East African species of torrent frogs belonging to the tropical African genus Petropedetes (P. dutoiti, P. martiennseni and P. yakusini). Taxonomic uncertainties are evident within this group: a putative new species reported...
