Abstract Entamoeba moshkovskii cysts are morphologically indistinguishable from those of the disease-causing species E. histolytica and nonpathogenic dispar. Although sporadic cases human infection with have been reported, organism is considered primarily a free-living ameba. No simple molecular detection tool available for diagnosing infections. We used polymerase chain reaction (PCR) to detect directly in stool. tested 109 stool specimens preschool children Bangladesh by PCR; 17 were...
The wide geographic distribution of Schistosoma mansoni, a digenetic trematode and parasite humans, is determined by the occurrence its intermediate hosts, freshwater snails genus Biomphalaria (Preston 1910). We present phylogenetic analyses 23 species Biomphalaria, 16 Neotropical seven African, including most important schistosome using partial mitochondrial ribosomal 16S complete nuclear ITS1 ITS2 nucleotide sequences. A dramatically better resolution was obtained combining data sets as...
Consuming raw vegetables offers essential nutrients that one may not get when such are usually cooked. However, eating them pose a great risk for transmissions of pathogens. Such risks be influenced by the sources and washing techniques used. The aim study was to compare prevalence diversity parasitic pathogens associated with sold at two types markets in Ghana effectiveness various techniques. We purchased batches samples cabbage, sweet bell pepper, carrot, lettuce, tomato onion within week...
Diarrhea is a major public health problem that affects the development of children. Anthropometric data were collected from 274 children with (N = 170) and without 104) diarrhea. Stool specimens analyzed by conventional culture, polymerase chain reaction for enteroaggregative Escherichia coli (EAEC), Shigella, Cryptosporidium, Entamoeba, Giardia species, enzyme-linked immunosorbent assay fecal lactoferrin levels. About 50% study population was mildly to severely malnourished. Fecal levels...
Hepatitis E virus (HEV) is highly endemic in several African countries with high mortality rate among pregnant women. The prevalence of antibodies to HEV Ghana not known. Therefore we evaluated the anti-HEV IgG and IgM women seen between months January May, 2008 at Obstetrics Gynaecology Department, Korle-Bu Teaching Hospital, Accra, Ghana. One hundred fifty-seven provided blood samples for unlinked anonymous testing presence HEV. median age participants was 28.89 ± 5.76 years (range 13–42...
Introduction Intestinal parasitic infections (IPIs) in school children are a public health problem most developing countries. Methods and principal findings A cross sectional survey was conducted from May to July 2016 with living overcrowded urban slums Accra, Ghana. simple random sample of 300 aged 2–9 years collected. The study used structured pre-tested questionnaire stool tests obtain information on epidemiological, sanitation habits, employment education status parents children. Data...
Island communities along the Volta Lake in southern Ghana present unique challenges for malaria control, characterized by high transmission rates, limited vector control measures, and isolated ecosystems. This study assessed diversity, seasonal abundance, transmission, insecticide resistance status of vectors these to inform effective strategies. Mosquitoes were collected from three island (Tuanikope, Allorkpem, Pediatorkope) using human landing catches, light traps, prokopack aspirators...
This study aimed to determine the prevalence and establish some risk factors associated with acquisition of gastrointestinal parasitic infections in school children Accra, Ghana.The overall intestinal infection was 15%. Giardia lamblia (10%) Schistosoma mansoni (1.7%) were common parasites found. Out 15% students postive for parasites, 13.6% had single 1.3% double infections. Children between ages 4-5 6-7 years (20% each) most The not significantly related gender (p = 0.1451), source...
This study was designed to investigate whether household cockroaches harbor cephalosporin-resistant enterobacteria that share resistance determinants with human inhabitants. From February through July 2016, whole cockroach homogenates and fecal samples from 100 households were cultured for (CRe). The CRe examined plasmid-mediated AmpC, ESBL, carbapenemase genes; antibiotic susceptibility patterns; conjugative transfer of mechanisms. Clonal associations between determined by multi-locus...
Reports from studies conducted in several countries indicate a high incidence of bacterial contamination donor blood. The prevalence blood and its products Ghana is not known. This study was to determine the at three major transfusion centers Greater Accra Region Ghana. Stored whole were cultured on different media, isolates identified using standard biochemical bacteriological methods. susceptibility selected antimicrobial agents also determined by disc diffusion method. overall rate 9%...
Cockroaches are common in the environment of many hospitals Ghana; however, little is known about their public health risks. To evaluate potential risks, we investigated external and internal microbial flora 61 cockroaches from a tertiary hospital Ghana evaluated antibiotic resistance profiles bacterial species. Standard methods were used all microbiological investigations susceptibility testing. A rotavirus carriage rate 19.7% was observed among cockroaches. Four types intestinal parasites...
Cyperus esculentus L, is a minor but important crop in Ghana. They are noted mostly by their aphrodisiac properties among others. The nuts often eaten raw as an unprocessed snack due to its rich flavour and texture. Though raw, the sometimes handled unhygienically, posing public health threat. This study therefore aimed at determining level distribution of parasitic bacterial contaminants associated with it sold. Four types intestinal parasites were identified, most prevalent was...
Introduction: though giardiasis is an important public health problem in Ghana, several aspects of its epidemiology, particularly the molecular epidemiology has not been investigated adequately. This could be a major hindrance to effective surveillance and control country. The study was carried out determine prevalence, risk factors genotypes Giardia lamblia infecting children at paediatric hospital Ghana.
