Rapid Detection of Carbapenemases Using NG-Test CARBA 5 in Positive Blood Cultures: A Diagnostic Test Study.

Background: Infections due to carbapenem-resistant Gram-negative bacteria are emerging as an important challenge in health-care settings and a growing concern worldwide. Lateral flow immunoassay NG-Test CARBA 5 can detect the five most reported carbapenemases (KPC, OXA-48-like, VIM, IMP, and NDM). Direct testing of positive blood cultures could reduce time to detection.

Risk Factors Associated with the Development of Hospital-Acquired Infections in Hospitalized Patients with Severe COVID-19.

Recognition of risk factors for hospital-acquired infections (HAI) in patients with COVID-19 is warranted. We aimed to describe factors associated with the development of HAI in patients with severe COVID-19. We conducted a retrospective cohort study including all adult patients admitted with severe COVID-19 between March 2020 and November 2020.

Trends of Mycobacterium bovis Isolation and First-Line Anti-tuberculosis Drug Susceptibility Profile: A Fifteen-Year Laboratory-Based Surveillance.

Background: Mycobacterium tuberculosis causes the majority of tuberculosis (TB) cases in humans; however, in developing countries, human TB caused by M. bovis may be frequent but undetected. Human TB caused by M.

[Efficacy and impact of polymerase chain reaction in the diagnosis of extrapulmonary tuberculosis].

Objective: To evaluate the efficacy of PCR in the diagnosis of extrapulmonary tuberculosis (TB) and its impact in the management of patients in a tertiary-care center in Mexico City.

Method: We conducted a retrospective study based on 40 clinical charts of patients to whom nested PCR was performed for the diagnosis of TB from June 1999 to December 2000. We reviewed the medical notes of 10 days before and 10 days after the PCR study to analyze its impact in the management of the patient.
