This study assessed the microbiological quality of various ready-to-eat foods sold in Alice, South Africa. Microbiological analysis was conducted on 252 samples which included vegetables, potatoes, rice, pies, beef and chicken stew. The isolates were identified using biochemical tests API 20E, 20NE Listeria kits; results analyzed one-way-ANOVA test. Bacterial growth present all food types tested; high levels total aerobic count observed 6.8 ± 0.07 followed by 6.7 1.7 while pies had lowest...
To investigate the antibacterial activity of Zingiber officinale (ginger) Garcinia kola (bitter kola) on four respiratory tract pathogens.
<b><i>Background:</i></b> <i>Helicobacter pylori</i> (<i>H</i>. <i>pylori</i>) infection is the most prevalent type of bacterial infection. Current guidelines from different regions world neglect specific African conditions and requirements. The Helicobacter Microbiota Study Group (AHMSG), founded in 2022, aimed to create an Africa-specific consensus report reflecting issues. <b><i>Summary:</i></b> Eighteen...
To determine the prevalence of Helicobacter pylori in patients with gastro-duodenal pathologies and susceptibility patterns isolates to currently recommended antibiotic treatment regimen used Cameroon.Consecutive dyspeptic referred Douala General Hospital, Cameroon for endoscopy were recruited study. Gastric biopsies collected from H. isolated identified following standard microbiology biochemical techniques. Antibiotic was determined by disk diffusion agar dilution methods against...
Abstract Background It has been observed that perturbations in the antioxidant defense systems, and consequently redox imbalance, are present many tissues of HIV-infected patients. Hence, exogenous supply antioxidants, as natural compounds scavenge free radicals, might represent an important additional strategy for treatment HIV infection. The aim this study was therefore to analyse phytochemical constituents potential Gasteria bicolor Haw Pittosporum viridiflorum Sims., two South African...
We assessed the bioactivity of G. kola seeds on Streptococcus pyogenes, Staphylococcus aureus, Plesiomonas shigelloides and Salmonella typhimurium. The crude ethyl acetate, ethanol, methanol, acetone aqueous extracts were screened by agar-well diffusion method their activities further determined Minimum Inhibitory Concentration (MIC) Bactericidal (MBC) assays. fractionated Thin Layer Chromatography (TLC). Bioautography was used to assess activity possible classes compounds present in more...
Pathogenic food‐borne bacteria have been associated with severe morbidity and mortality in humans animals. This study was aimed at determining the prevalence of Staphylococcus aureus, Salmonella spp., Escherichia coli present cattle pigs slaughtered selected abattoirs Vhembe District susceptibility isolates to antibiotics. A total 176 swab samples (28 16 pigs) rump, flank, brisket, neck animals were analyzed using standard microbiological methods. E. genotyped detect pathogenic strains. Of...
Globally, malaria in recent years has witnessed a decline the number of cases and death, though most world report shows slight decrease 2018 compared to 2017 and, increase 2016. Africa remains region with greatest burden disease. Cameroon is among countries very high malaria, coastal forest regions carrying highest Nkongho-mbeng typical rural setting equatorial rain Cameroon, no existing knowledge epidemiology this locality. This study aimed at determining current status Nkongho-mbeng. A...
Introduction Despite a high fatality rate in humans, little is known about the occurrence of Crimean-Congo hemorrhagic fever virus (CCHFV) Cameroon. Hence, this pioneer study was started with aim determining prevalence CCHFV domestic ruminants and its potential vector ticks Methods A cross-sectional carried out two livestock markets Yaoundé to collect blood from cattle, sheep, goats. CCHFV-specific antibodies were detected plasma using commercial ELISA assay confirmed modified...
Summary Objective To determine the prevalence and identify intra‐familial risk factors associated with Helicobacter pylori infection in a paediatric population. Methods Cross‐sectional study Buea Limbe health districts, South West Cameroon. Stool samples were collected from 176 randomly selected apparently healthy children two communities different socioeconomic status. They comprised 86 males 90 females aged 0–10 years mean age of 4.29. status was determined using an enzyme‐linked...
Rickettsia africae was identified in seven (6%) of 118 patients with acute fevers unknown etiology proven not to be malaria or typhoid fever from clinics along the coastal region Cameroon by polymerase chain reaction (PCR) amplification and sequencing citrate synthase (gltA) outer membrane protein A (ompA) genes Rickettsia. The majority (71%) were female. Clinical manifestations included (100%), headache (71%), myalgia arthralgia (43%), pulmonary involvement (29%), diffuse rash (14%)....
This study evaluated the effects of growth medium, temperature, and incubation time on biofilm formation by Enterobacter cloacae strains. The ability to adhere a surface was demonstrated using microtiter plate adherence assay whereas role cell properties in assessed coaggregation autoaggregation assays. architecture biofilms examined under scanning electron microscope (SEM). All strains adhered well when incubated for 48 h, irrespective medium temperature. It also noted that 90% 73% prepared...
Objectives. We examined Helicobacter pylori infection in patients with gastric-related morbidities at Livingstone Hospital, Port Elizabeth, to determine the prevalence and risk factors for according race, endoscopic diagnosis, age sex. Methods. Gastric biopsies were collected from 254 consecutive H. isolated on Columbia agar base supplemented 7% sheep's blood Skirrow's supplement containing trimethoprim (2.5 mg), vancomycin (5 mg) cefsulodin mg). Amphotericin was added medium. Recovered...
The aim of this study was to identify sources cheap starting materials for the synthesis new drugs against Helicobacter pylori. Solvent-extracts selected medicinal plants; Combretum molle, Sclerocarya birrea, Garcinia kola, Alepidea amatymbica and a single Strychnos species were investigated 30 clinical strains H. pylori alongside reference control strain (NCTC 11638) using standard microbiological techniques. Metronidazole amoxicillin included in these experiments as positive antibiotics....
