Infectious diarrhoea contributes to high morbidity and mortality in young children from sub-Saharan Africa. The aim of this study was to assess the prevalence of single and multiple diarrhoeal-causing pathogen combinations in children suffering from diarrhoea from rural and peri-urban communities in South Africa. A total of 275 diarrhoea stool specimens were collected between 2014 and 2016 from Hospitals and Primary Health Care clinics. The BioFire FilmArray Gastrointestinal panel was used to simultaneously detect 22 diarrhoea pathogens (viruses, bacteria, parasites) known to cause diarrhoea. A total of 82% (226/275) enteric pathogens were detected in the stool specimens. The two most detected bacterial, viral and parasitic pathogens each included: EAEC (42%), EPEC (32%), Adenovirus F40/41 (19%), Norovirus (15%), Giardia (8%) and Cryptosporidium (6%), respectively. Single enteric pathogen infections were recorded in 24% (65/275) specimens with and was found in 26% (17/65) and 14% (9/65) of the specimens, respectively. Multiple enteric pathogen combinations were recorded in 59% (161/275) of the stool specimens with 53% (85/161) containing two pathogens, 22% (35/161) containing three pathogens and 25% (41/161) containing four or more pathogens. The results from this study demonstrated the complex nature of pathogen co-infections in diarrhoeal episodes which could have an impact on treatment effectiveness.

Contribution of domestic animals' feces to the occurrence of diarrhoea among children aged 6-48 months in Sidama region, Ethiopia: a laboratory-based matched case-control study.
BMJ Glob Health

Division of Water and Health, Ethiopian Institute of Water Resources, Addis Ababa University, Addis Ababa, Ethiopia.
Background: In developing countries, due to improper management of domestic animals' exposures, under-five (U5) children have been affected by diarrhoea. However, there is no evidence that shows the presence of diarrhoea-causing pathogens in the faeces of U5 children and animals residing in the same houses in the Sidama region, Ethiopia.
Methods: A laboratory-based matched case-control study was conducted on children aged 6-48 months in the Sidama region of Ethiopia from February to June 2023.

Shiga toxin-producing (STEC) is a group of bacteria that causes gastrointestinal illness and occasionally causes large foodborne outbreaks. It represents a major public health concern due to its ability to cause severe illness which can sometimes be fatal. This study was undertaken as part of a rapid investigation into a national foodborne outbreak of STEC O145.

Background: Blastocystis is a prevalent intestinal parasitic protist that infects both birds and animals. There are at least 44 subtypes (ST) of Blastocystis, with ST1-ST9 being found in humans. The correlation between specific subtypes and pathogenicity has not been definitively established.

For infections, highly sensitive rapid diagnostic test kits are necessary for prompt diagnose and infection control. In this study, we evaluated "Quick Chaser CD GDH/TOX" (evaluation kit), a rapid diagnostic kit for , using 65 clinical stool specimens, comparing with GE test immunochromato-CD GDH/TOX "Nissui" (GE test) and TECHLAB QUIK CHEK COMPLETE (QUIK CHEK). The results of the evaluation kit showed a high concordance rate; 100% the positive concordance rate (31/31) and 97.

Many technical aspects are associated with helminth egg isolation and enumeration that affect how efficiently eggs are recovered from samples. This study investigated Ascaris egg recoverability when samples were washed with or without pressure, and from different sample types (water, effluent, ventilated improved pit latrine [VIP], urine diversion dry toilet [UDDT], dried, fatty, and septic tank sludges, and soil) when processed with water, ammonium bicarbonate, and 7X®. We also looked at egg recovery after flotation with zinc sulfate, magnesium sulfate, and sodium nitrate at specific gravities of 1.
