ABSTRACT: Staphylococcus
xylosus is a species of bacteria belonging to the genus Staphylococcus. This genus currently
includes several species and subspecies. We distinguish between 2 groups: the group of
coagulase-positive staphylococci (CoPS) and coagulase-negative staphylococci (CoNS), a larger group that includes
more than forty species and subspecies. Among the CoNS, Staphylococcus
xylosus occupies a special place because it is frequently isolated from
meats, dairy products, and
agricultural environments. It is commonly used in fermentation due to its
primary role in the flavor and color development of fermented products. It is a commensal bacterium
of the skin of small mammals and farm animals, where it constitutes the
majority of flora. In this
species, there are a large number of strains, including phenotypes and
genotypes. Although S. xylosus is
actually a recognized non-pathogenic species, a few strains can be potentially dangerous. They can thus be responsible for
mastitis and dermatitis in cattle. With the multiplicity
of breeding farms, the consumption of livestock products and the increasingly
frequent contact of humans with animals a few
rare cases of human opportunistic infections have also been reported in the
literature. These include pyelonephritis, endocarditis, urinary, lymphatic, and lymph node infections, contamination of orthopedic materials and
catheters. Thereby, we
report the case of a lingering and chronic infection of the lacrimal tract by Staphylococcus xylosus in an 8-year-old
child in the Ophthalmology Department of Sikasso hospital
in Mali.
