Review on Experimental Treatment Strategies Against <em>Trypanosoma cruzi</em>

Chagas disease is a neglected tropical disease caused by the protozoan Trypanosoma cruzi. Currently, only nitroheterocyclic nifurtimox (NFX) and benznidazole (BNZ) are available for the treatment of Chagas disease, with limitations such as variable efficacy, long treatment regimens and toxicity. Different strategies have been used to discover new active molecules for the treatment of Chagas disease. Target-based and phenotypic screening led to thousands of compounds with anti-T. cruzi activity,…

Affinity of Mycobacterium tuberculosis strains for M059K microglial cells after migration through A549 alveolar epithelium

Tuberculosis (TB) remains a major threat worldwide while central nervous system TB (CNS-TB) is one of the most severe forms of extrapulmonary TB. CNS-TB develops as a secondary infection during the hematogenous spread of Mycobacterium tuberculosis (M. tuberculosis) from the lungs to the CNS. Factors influencing the dissemination of the bacilli to the CNS have not been studied extensively. This study evaluated the transmigration ability through the alveolar epithelium and adhesion and invasion…

Metabolic fitness of <em>Candida albicans</em> is indispensable for functional drug efflux, ergosterol, and chitin biosynthesis

CONCLUSION: Based on the findings, the disruption of GC affected efflux activity and the synthesis of ergosterol and chitin. The present study for the first time revealed that metabolic fitness was associated with functional drug efflux, ergosterol and chitin biosynthesis and validated GC as an antifungal target. However, further studies are needed to comprehend and exploit this therapeutic opportunity.

Patient- and provider-related factors in the success of multidrug tuberculosis treatment in ColombiaFatores de êxito do tratamento da tuberculose multirresistente relacionados com o paciente e com a equipe de saúde na Colômbia

CONCLUSIONS: Some characteristics of patients and healthcare providers influence treatment success in MDR-TB cases. Physicians’ and nurses’ knowledge about MDR-TB must be improved, and follow-up of MDR-TB patients who are living with HIV and of those affiliated with the subsidized health insurance scheme in Colombia must be strengthened, as these patients have a lower likelihood of a successful treatment outcome.
