Closer attention should be paid to vitamin D status in patients with mycobacterial diseases.

BACKGROUND: Non-tuberculous mycobacteria (NTM) can cause chronic lung infection particularly in patients who have structural lung disease such as cystic fibrosis (CF). We evaluated the incidence and management of NTM infections in patients with CF in our center. METHODS: A retrospective cohort study was carried out on CF patients having at least one positive NTM isolate between 2012 and 2020. RESULTS: Ten patients (2.1%) had at least one positive NTM culture from respiratory samples...

The detection of Mycobacterium tuberculosis complex DNA by PCR using formalin-fixed paraffin-embedded material has become an integral part of molecular-pathological diagnostics. We describe an approach that enables the detection of contamination by using Mycobacterium szulgai as a positive control, contributing to the reduction of false-positive results.

INTRODUCTION AND OBJECTIVE: Fish mycobacteriosis is a chronic granulomatous disease caused by several species of bacteria from the genus Mycobacterium , described as nontuberculous mycobacteria (NTM). The most important species causing fish mycobacterioses are M. chelonae, M. fortuitum , and M. marinum . Mycobacteria infecting fish also include zoonotic pathogens. M. marinum is the cause of most cases of fish-related mycobacterial infection in humans. The disease occurs more frequently in workers in the fishing industry, people whose hobbies involve water activities, and aquarists...

Background : non-tuberculous mycobacteria (NTM) infect humans and animals and have a critical confounding effect on the diagnosis of bovine tuberculosis. The Official Mexican Standard (Norma Oficial Mexicana, NOM-ZOO-031-1995) for food safety regulates Mycobacterium bovis in cattle, but not the NTM species. The study's objective was to isolate and identify the NTM present in condemned bovine lymph nodes in a slaughterhouse, characterize the histological lesions, and correlate bacteriological and microscopic findings with the antemortem tuberculin skin test...

Cancers are one of the risk factors of non-tuberculous mycobacterial (NTM) lung disease. The majority of data in this group of patients concern infections caused by Mycobacterium avium -the most prevalent NTM species worldwide. In contrast, limited information can be found regarding the uncommon NTM such as Mycobacterium szulgai . We present the case of M. szulgai lung disease in a patient with a history of breast cancer. Coexistence of NTM lung disease and breast cancer lung metastasis as well as primary lung cancer was suspected...

Non-tuberculous mycobacteria are of public health significance, and zoonotic infection is attributed to the sociocultural practice of consumption of raw milk and the close human-livestock contact in pastoral communities. This study aimed at isolation, identification of mycobacteria from human sputum and camel milk and risk factors assessment in Samburu East, Kenya. Six hundred and twelve camels and 48 people presumed to have tuberculosis (TB) from 86 households in Wamba and Waso regions were screened. Camels were categorized into Somali, Turkana and Rendile breeds...

A 40-year-old woman with severe anorexia nervosa was found to have a bilateral pulmonary infection with rare atypical mycobacterium Mycobacterium szulgai. Of note, she had no preexisting structural lung disease or history of tuberculosis, smoking, or HIV. Current data suggest that both impaired cell-mediated immunity and altered respiratory mechanics are risk factors for mycobacterial infection in patients with anorexia nervosa.

Incidence of nontuberculous mycobacterial infections has increased during the past decades. Disseminated infections are relatively rare and associated with immunocompromised status. We report a case of disseminated Mycobacterium szulgai infection of cervical lymphadenitis and pulmonary involvement with positive anti-interferon-gamma autoantibodies. The patient was successfully treated with rifampin, ethambutol, and clarithromycin. The case reports and series through search engines of Pubmed and Google with the keyword of disseminated infection of M...

The article presents data on the structure of acid-resistant members of the order Actinomycetales and rare species that have been isolated and identified using various methods. The study included strains of non-tuberculous mycobacteria (NTM) isolated from clinical material during examination for tuberculosis in the period from 2016 to 2019. The total number of samples with signs of NTMs growth that were included in the study was 316 samples. Primary isolation on Levenshtein-Jensen, Finn II, and MGIT media and NTMs identification by DNA-hybridization...

INTRODUCTION: Infection with non-tuberculosis mycobacteria (NTM) has been on the rise globally causing a wide spectrum of respiratory and extrapulmonary infections in humans. Studies on these pathogens from the Middle-East including Lebanon are scarce. METHODOLOGY: This retrospective study addresses the approach used for investigation, speciation and antimicrobial resistance (AMR) profiles of recovered NTM isolates from respiratory sources at a major tertiary care center in Lebanon during two periods (2003-2007 and 2013-2017)...

In this study, mycobacteria, which were previously identified as Mycobacterium tuberculosis complex (MTC), and mycobacteria other than tuberculosis (MOTT) with cord factor and the p-nitro-alpha-acetyl-amino-beta-hydroxypropiophenone (NAP) test were reanalysed using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis method in order to confirm the identification, and at the same time, species accepted as MOTT were identified. Although the results of the NAP test were obtained within 3-5 days, the PCR-RFLP results were obtained in 1 day...

Risk factors and prevalence of pulmonary nontuberculous mycobacterial (NTM) diseases were retrospectively evaluated in 1208 suspected pulmonary TB patients seeking care at the Affiliated Hospital of Hangzhou Normal University between July 2018 and December 2018. Further analysis of 390 culture-positive cases demonstrated that 358 (358/390, 91.8%) were infected with Mycobacterium tuberculosis (MTB), 24 (24/390, 6.2%) with NTM and eight (8/390, 2.0%) with both MTB and NTM. M. intracellulare was the most prevalent NTM isolated (16/24, 66...

The diagnosis of tuberculosis (TB) in camels at slaughter houses heavily relies on post mortem (PM) meat inspection to detect granulomatous lesions; however, the sensitivity of this technique is not perfect. The objective of this study was to isolate and characterize mycobacteria associated with suspect TB pathological lesions at PM. At PM, 1600 camels were examined in two county slaughterhouses. One hundred and thirty two, 8.25% (132/1600) (Binomial CI 95% 6.95-9.71%), suspect granulomatous lesions were found...

Most of the nontuberculous mycobacteria (NTM) are opportunistic pathogenic microorganisms and free-living in nature. NTM can cause a wide range of infections. However, pulmonary NTM disease is the most frequent clinical picture. The aim of this study was to identify and evaluate drug susceptibility of slow growing NTM isolated from pulmonary samples of patients prediagnosed as tuberculosis between 2014 and 2018 in Atatürk Chest Diseases and Chest Surgery Training and Research Hospital Microbiology Laboratory by a commercial microtube dilution plaque method...

The size nature of sludge flocs could affect the occurrence and distribution of bacterial pathogens in wastewater treatment plants (WWTPs). In this study, the floc-size dependence of bacterial pathogens in the activated sludge of a WWTP was investigated using high-throughput metagenomic sequencing approaches. The results showed that a total of 423 pathogenic species belonging to 123 genera were identified in the three size-fractionated flocs. Also, we found that all the pathogens on the WHO's global priority pathogens list were detected in the size-fractionated flocs, with relative abundance of 0...

Water and wet soil samples from the periphery of ponds used by the community were collected from districts of Purulia of West Bengal and Champa of Chhattisgarh, India. Samples were processed and decontaminated followed by culturing on Lowenstein Jensen (LJ) media. Polymerase chain reaction (PCR) was performed using 16S rRNA gene target of mycobacteria and species was confirmed by sequencing method...

Background: Zoonotic tuberculosis, commonly referred to as bovine, tuberculosis is mainly caused by Mycobacterium bovis subsp. bovis, a member of the mycobacterium tuberculosis complex (MTBC). Infection in humans resembles that caused by Mycobacterium tuberculosis. Mycobacteria Other Than Tuberculous (MOTTs) are also increasingly being associated with tuberculosis humans but reports of infections in animals are scarce, their zoonotic potential being largely ignored. The study aimed to determine the aetiology and public health importance of mycobacteriosis in slaughter cattle in Kenya...
