To date, the public health relevance of mycobacterial infections in pigs is not well investigated despite high risk of infection. Recently, there has been a documented increase in opportunistic infections and risk of acquiring opportunistic mycobacterial infections in HIV/AIDS patients in Mubende district; unfortunately, there has been no published information on the epidemiology of mycobacterial infections in this area. This study was carried out between September 2008 and February 2009. Investigations were done to assess the prevalence and associated risk factors of mycobacterial infections in slaughtered pigs in Mubende district of Uganda. A total of 997 pigs (53.7% male and 46.3% female) from 31 different slaughterhouses were examined for the presence of lesions compatible with TB and mycobacterial infections. Pathologic tissue specimens were collected for culturing and isolation of mycobacteria. A cross-sectional technique was used based on convenient visits to slaughterhouses but random selection of individual slaughtered pigs for a detailed post-mortem inspection on a daily basis. The results reflected a 9.3% and 3.1% (95% CI) prevalence of Mycobacterium species based on necropsy examinations and culture isolation, respectively. The highest prevalence of mycobacterial infection was recorded in Buwekula County (the mixed agro-zone) whilst the lowest was in Kassanda County (pastoral zone). A multivariable logistical regression analysis identified age (P < or = 0.001) and sex (P < or = 0.05) as risk factors for mycobacterial infections in pigs. Post-estimation statistics of the regression model evaluation and validation fit it well into the data (HL, chi (2) = 5.9; P = 0.69 for necropsy, HL chi (2) = 2.9; P = 0.94 for culturing). This study documented a high prevalence of mycobacterial infections in slaughter pigs in Mubende district. The fact that pigs and human often share common housing and environment poses a high risk of zoonotic transmission. This then warrants further molecular investigation to identify the specific Mycobacterium species and their public health importance in this area.

Unlabelled: is an acid-fast, aerobic, non-motile, and biofilm-forming bacterium. The increasing prevalence of mycobacterial infections makes it necessary to find new methods to combat the resistance of bacteria to conventional antibiotics. is an emerging pathogen that is intrinsically drug resistant due to several factors, including an impermeable cell envelope, drug efflux pumps, target-modifying enzymes, and the ability to form thick, robust biofilms.

Background: Subjects with immune-mediated inflammatory diseases (IMID), such as rheumatoid arthritis, with tuberculosis infection (TBI), have a high probability of progressing to tuberculosis disease (TB). We aim to characterize the impact of IMID on the immune response to (Mtb) in patients with TBI and TB disease.
Methods: We enrolled TBI and TB patients with and without IMID.

We present a rare case of asymptomatic allergic bronchopulmonary aspergillosis (ABPA) concurrent with active pulmonary tuberculosis. Allergic bronchopulmonary aspergillosis is an immunological pulmonary disorder characterized by hypersensitivity to Aspergillus fumigatus, while pulmonary tuberculosis (PTB) is a complex infection caused by Mycobacterium tuberculosis (MTB). The association between pulmonary tuberculosis infections and Aspergillus infections remains a fascinating area of inquiry.

Methods: We conducted 56 in-depth interviews with persons with TB ( = 12), TB healthcare workers (HCWs) ( = 10), TB lay HCWs ( = 10), and leaders/owners ( = 12) and attendees ( = 12) of community venue types identified as potential TB transmission locations.
Correlation between rrs gene mutations and amikacin resistance in Mycobacterium abscessus: implications for fitness cost and clinical prevalence.

Objectives: Amikacin is crucial for treating Mycobacterium abscessus (Mab) infections, with resistance primarily attributed to rrs gene mutations. The correlation between specific mutations and amikacin susceptibility, along with the associated fitness cost, requires further investigation.
Methods: We isolated spontaneous amikacin-resistant mutants in vitro and identified their mutation sites in the rrs gene via Sanger sequencing, which were then compared with existing reports.
