Uncovering a Novel 51A Mutation and Antifungal Resistance in through Culture Collection Screening.

Background: is an important concern for immunocompromised individuals, often resulting in severe infections. With the emergence of resistance to azoles, which has been the therapeutic choice for infections, monitoring the resistance of these microorganisms becomes important, including the search for mutations in the 51A gene, which is the gene responsible for the mechanism of action of azoles. We conducted a retrospective analysis covering 478 isolates.

Detection of Pneumocystis jirovecii by nested PCR in HIV-negative patients with pulmonary disease.

Background: Nested PCR can be used to determine the status of Pneumocystis jirovecii infection in other lung diseases.

Aims: This study sought to detect a target DNA fragment (mitochondrial large subunit rRNA or mtL SUrRNA) of P. jirovecii in patients with lung disease who underwent bronchoscopy with collection of bronchoalveolar lavage (BAL).
