Geophagia: Benefits and potential toxicity to human-A review.

Geophagy is the habit of consuming clay soil such as chalk or kaolin. Though it is globally practiced, the safety of those involved is yet to be fully established. It is thought to be highly prevalent in pregnant women because of its antinausea or therapeutic effects.

Proximate composition, microbiological quality and presence of total aflatoxins and aflatoxin B in the flesh of three snails' species ( and ) from a selected locality of Yaoundé, Cameroon.

The increasing need for animal proteins has led to an interest in non-conventional protein sources such as snails. Although several species of snails are locally reared and highly prized by Cameroonians, there is a lack of information regarding their composition and safety. This work aimed at assessing the chemical composition, the microbiological quality and the total aflatoxins (AFs) and aflatoxin B (AFB) contents of the fleshes from three snails' species traditionally reared in the city of Yaoundé, Cameroon.

Detection of Antimicrobial Resistance, Pathogenicity, and Virulence Potentials of Non-Typhoidal Isolates at the Yaounde Abattoir Using Whole-Genome Sequencing Technique.

One of the crucial public health problems today is the emerging and re-emerging of multidrug-resistant (MDR) bacteria coupled with a decline in the development of new antimicrobials. Non-typhoidal Salmonella (NTS) is classified among the MDR pathogens of international concern. To predict their MDR potentials, 23 assembled genomes of NTS from live cattle (n = 1), beef carcass (n = 19), butchers’ hands (n = 1) and beef processing environments (n = 2) isolated from 830 wet swabs at the Yaounde abattoir between December 2014 and November 2015 were explored using whole-genome sequencing.

Human and Animal RNA Virus Diversity Detected by Metagenomics in Cameroonian Clams.

Many recent pandemics have been recognized as zoonotic viral diseases. While their origins remain frequently unknown, environmental contamination may play an important role in emergence. Thus, being able to describe the viral diversity in environmental samples contributes to understand the key issues in zoonotic transmission.

Contamination of Clams with Human Norovirus and a Novel Hepatitis A Virus in Cameroon.

Shellfish constitute an important protein source but may be contaminated by viruses from various origins. A study performed on clams collected in Cameroon showed a high prevalence of norovirus and hepatitis A virus. After sequencing, the hepatitis A virus showed similarities with the genotype V simian strains.
