The efficacy of many compounds against is often limited when administered via conventional oral or injection routes due to suboptimal pharmacokinetic characteristics. Inhalation-based delivery methods have been investigated to achieve high local therapeutic doses in the lungs. However, previous models, typically employing wild-type strains, were intricate, time-consuming, labor-intensive, and with poor reproducibility.

A major challenge in tuberculosis (TB) therapeutics is that antibiotic exposure leads to changes in the physiology of (), which may enable the pathogen to withstand treatment. While antibiotic-treated has been evaluated in experiments it is unclear if and how long-term treatment with diverse antibiotics with varying treatment-shortening activity (sterilizing activity) affects physiologic processes differently. Here, we used SEARCH-TB, a pathogen-targeted RNA-sequencing platform, to characterize the transcriptome in the BALB/c high-dose aerosol infection mouse model following 4 weeks of treatment with three sterilizing and three non-sterilizing antibiotics.

Background: Cutaneous tuberculosis is a rare form of the disease that defies diagnosis due to the diversity of clinical presentations. This study was based on the reality of a dermatology referral center in the Brazilian Amazon region to detail several characteristics of this disease.
Objective: To describe a series of cases of cutaneous tuberculosis treated at a dermatology service in the Brazilian Amazon region, addressing epidemiological aspects, clinical forms, diagnostic methods, treatment, and outcomes.

Tuberculosis (TB) is historically the world's deadliest infectious disease. New TB drugs that can avoid pre-existing resistance are desperately needed. The β-lactams are the oldest and most widely used class of antibiotics to treat bacterial infections but, for a variety of reasons, they were largely ignored until recently as a potential treatment option for TB.
