Dissemination of Mycobacterium tuberculosis is associated to a SIGLEC1 null variant that limits antigen exchange via trafficking extracellular vesicles

Journal of Extracellular Vesicles, Volume 10, Issue 3, January 2021., 2021
Abstract The identification of individuals with null alleles enables studying how the loss of gene function affects infection. We previously described a non‐functional variant in SIGLEC1, which encodes the myeloid‐cell receptor Siglec‐1/CD169 implicated in HIV‐1 cell‐to‐cell transmission.

A Preliminary Study on Public Health Implications of Avian Tuberculosis in Selected Districts of the Oromia Region, Ethiopia

Veterinary Medicine International, Volume 2021, Issue 1, 2021., 2021
Background. Avian tuberculosis is a zoonotic disease which remains a problem in extensive poultry production systems under which chickens scavenge for survival in unhygienic environments. Methodology. A cross‐sectional study was conducted from November 2016 to June 2017 at high‐land areas of Gerar Jarso and Ada’a and Boset districts located at mid and ...

Mycobacterial Spindle Cell Pseudotumor in an 18-Year-Old Female With Congenital HIV: A Case Report and Literature Review. [PDF]

Case Rep Med
Mycobacterial spindle cell pseudotumor (MSP) is an uncommon granulomatous inflammation often found in immunocompromised patients, especially those with HIV. This case report discusses an 18‐year‐old female with congenital HIV, who presented with severe epigastric pain, nausea, and noteworthy lymphadenopathy. Imaging studies identified lobulated masses,

Hyperammonemia in Generalized Mycobacterium genavense Infection after Renal Transplantation [PDF]

American Journal of Transplantation, 2007
After solid organ transplantation, patients are susceptible to infection caused by uncommon pathogens due the immunosuppressive drug therapy. Here, we report the first case of disseminated Mycobacterium genavense infection in a HIV seronegative renal transplant patient. The most striking clinical feature was a decreased consciousness.

Social network analysis and whole-genome sequencing to evaluate disease transmission in a large, dynamic population: A study of avian mycobacteriosis in zoo birds.

PLoS ONE, 2021
This study combined a social network analysis and whole-genome sequencing (WGS) to test for general patterns of contagious spread of a mycobacterial infection for which pathways of disease acquisition are not well understood.

Mycobacteriosis in Various Pet and Wild Birds from Germany: Pathological Findings, Coinfections, and Characterization of Causative Mycobacteria

Microbiology Spectrum, 2022
A total of 50 birds diagnosed with mycobacteriosis were examined for pathomorphological lesions, coinfections, and causative agents. Mycobacterial species were identified and isolates differentiated using multilocus sequence typing (MLST) and ...

The looming tide of nontuberculous mycobacterial infections in Portugal and Brazil [PDF]

, 2016
Nontuberculous mycobacteria (NTM) are widely disseminated in the environment and an emerging cause of infectious diseases worldwide. Their remarkable natural resistance to disinfectants and antibiotics and an ability to survive under low-nutrient ...

Evolution and expansion of the PE and PPE multigene families and their association with the duplication of the ESAT-6 () gene cluster regions [PDF]

, 2006
Background The PE and PPE multigene families of Mycobacterium tuberculosis comprise about 10% of the coding potential of the genome. The function of the proteins encoded by these large gene families remains unknown, although they have been proposed to be

Gene and whole genome analyses reveal that the mycobacterial strain JS623 is not a member of the species Mycobacterium smegmatis [PDF]

, 2016
Unexpected differences were found between the genome of strain JS623, used in bioremediation studies, and the genome of strain mc2155, a model organism for investigating basic biology of mycobacteria.
