Non-tuberculous mycobacteria (NTM) can cause diseases not only in individuals with compromised immune systems but also in those with normal immune function. This study aimed to compare the prevalence of NTM in Türkiye and worldwide between 2012 and 2022. This study was designed following the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) procedure. A systematic search was conducted between January 2012 and September 2022 using different electronic databases, including Pubmed, Medline, Embase, Web of Science, Ebsco, Scopus, Türk Medline, and Google Scholar. During the literature review process, titles and abstracts were examined and the full texts of the studies were accessed. In 13 research articles from Türkiye included in the study, a total of 17.293 samples were studied and a total of 1304 NTM (7.54%) strains were isolated from these samples. Among the 1304 NTM strains reported from Türkiye, the top three most frequently isolated species were M. abscessus (29.83%), M. lentiflavum (14.97%), M. fortuitum (14.38%). In 35 studies included from around the world, a total of 512.626 samples were studied and a total of 12.631 NTM (2.46%) strains were isolated from these samples. Among the 12631 NTM strains isolated, the top three most frequently isolated species were M. intracellulare (28.13%), M. avium (17.70%) and M. abscessus (14.88%). This study unveiled the global prevalence of NTM-infected patients, detailing species distribution and microbiological diagnostic methods. Variations in NTM spread were observed, influenced by diverse factors.

Understanding the diversity of microscopic hyphomycetes is an ongoing effort, and many species remain undescribed. While studying lichen organismal composition in western Canada, metagenomic data revealed the presence of an unknown species of (, Ascomycota), a genus of pollen-parasitic fungus with no previous records in the region. We developed genus-specific primers to amplify DNA in lichen and adjacent substrate extractions, successfully detecting multiple lineages of across a wide geographic range within North America.

Fatal infections with the rare COUG strain of the zoonotic parasite Toxoplasma gondii were recently detected for the first time in four southern sea otters (Enhydra lutris nereis) exhibiting severe protozoal steatitis. The objectives of this study were to describe new COUG strain infections in sea otters, investigate the potential contributory role of a recently discovered parasite-infecting narnavirus (Apocryptovirus odysseus) in these infections, assess the potential contribution of vitamin E deficiency in the development of systemic steatitis, and explore the utility of serotyping for strain-specific diagnosis of T. gondii infections in sea otters.

There is no vaccine for severe malaria. STEVOR antigens on the surface of -infected red blood cells are implicated in severe malaria and are targeted by neutralizing antibodies, but their epitopes remain unknown. Using computational immunology, we identified highly immunogenic overlapping B- and T-cell epitopes (referred to as multiepitopes, 7-27 amino acids) in the semiconserved domain of four STEVORs linked with severe malaria and clinical immunity.

The nitrogen-fixing, chemolithoautotrophic genus is found across numerous diverse environments worldwide and is an important member of many ecosystems. These species serve as model systems for their metabolic properties and have industrial applications in bioremediation and sustainable protein, food and fertilizer production. Despite their abundance and utility, the majority of strains are without a genome sequence, and only eight validly published species are known to date.

Background: The river ecosystems provide habitats and source of water for a number of species including humans. The uncontrolled accumulation of pollutants in the aquatic environment enhances the development of antibiotic-resistant bacteria and genes.
Methods: Water samples were collected seasonally from different sites of Gomti and Ganga River.
