The paper presents the results of studying the time course of changes in tuberculosis antibodies by enzyme immunoassay (EIA) and immune blotting (IB) in 34 patients with pulmonary tuberculosis. In 76.5% of cases, EIA were established to reveal tuberculosis antibodies whose concentration is most pronounced in lung tissue destruction. The detection rate of specific antibodies to Mycobacterium tuberculosis (MBT) structural components by IB was 100%, which was 23.6% greater than that by EIA. The MBT structural components with a molecular weight of 11-20, 21-30, and 101-160 kDa were found to have high immunogenic properties, as suggested by the maximum levels of antibodies and by the marked antigenic proteins of proteins with a molecular weight of 11-20, 21-30, and 41-50 kDa, which showed itself as the generation of the maximum levels of circulating immune complexes with antigens of this specificity.

Mycobacterial infections are an important emerging zoonosis in companion animals for which diagnostic options remain imperfect, and the canine immunological response to these infections has been poorly investigated. We sought to further define the cellular response of peripheral blood mononuclear cells (PBMCs) from dogs infected with , as determined using a commercial interferon-gamma response assay (IGRA). To this end, PBMCs from healthy or infected dogs were collected.

Background: Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibrous inflammatory disease. Recently, an association between IgG4-RD and tuberculosis (TB) has been reported.
Case Summary: We report a 56-year-old man complaining of a cough and poor appetite for 2 months and oliguria for 1 day.

Background: The common diagnostic methods for tuberculosis have been showing reduced sensitivity among chronic obstructive pulmonary disease patients. This study was conducted to evaluate and analyse the diagnostic value of an interferon-γ release assay in COPD patients complicated with pulmonary tuberculosis.
Methods: A nested case-control study was conducted on 123 COPD patients hospitalized at the Fifth Hospital of Shijiazhuang, Hebei Province, from January 2019 to June 2021.

This study evaluated the association between HIV risk perception and sociodemographic and behavioral characteristics among cisgender female sex workers in the five regions of Brazil. A cross-sectional, multicenter study using respondent-driven sampling was used. Sex workers over 18 years of age and who reported commercial sex in the past four months were included.
