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.
