Introduction:Personal protective equipment (PPE) complements the safety measures required for working in various laboratories. The main purpose of PPE is to limit the exposure of laboratory personnel and the environment to hazardous chemicals and biological materials. Despite the wide acceptance of PPE, limited accommodation exists for customization of these items based on personal or cultural preferences.Discussion:This article describes the basic recommendations and specifications for Muslim women's head covers as a part of PPE requirements in chemical and biological laboratories.Conclusions:These guidelines will significantly help safety professionals, laboratorians, and teachers to plan accordingly and customize PPE that will not only be safe but also fit the needs of scientists of varying cultural backgrounds.

Stealthy intracellular bacterial pathogens are known to establish persistent and sometimes lifelong infections. Some of these pathogens also have a tropism for the reproductive system, thereby increasing the risk of reproductive disease and infertility. To date, the pathogenic mechanism involved remains poorly understood. Here, we demonstrate that Brucella abortus, a notorious reproductive pathogen, has the ability to infect the nonpregnant uterus, sustain infection, and induce inflammatory changes during both acute and chronic stages of infection.
