Studysummary This study found that in mice, Bacillus anthracis infections destroy hair follicles by progressing inward from the surface and clear when inflammatory cells disperse the bacteria after 3-4 days. Our plain-language summary of this paper — not a Tressless recommendation.
The study investigated the susceptibility of hair follicles to Bacillus anthracis in a murine model, focusing on whether actively growing (anagen) or resting (telogen) follicles were more prone to infection. The results showed that B. anthracis could invade both anagen and telogen hair follicles equally, unlike dermatophytes which only infect anagen follicles. The infection typically started at the superficial parts of the follicles and progressed deeper. This research provided insights into the pathogenesis of cutaneous anthrax, highlighting the role of hair follicles as a site of bacterial proliferation.
