Multidisciplinary Effort Leading to Effective Tuberculosis Community Outbreak Containment in Israel.

Tuberculosis (TB) is the second-most prevalent cause of mortality resulting from infectious diseases worldwide. It is caused by bacteria belonging to the Mycobacterium tuberculosis complex (MTBC). In Israel, TB incidence is low, acknowledged by the WHO as being in a pre-elimination phase.

Prolonged survival of a patient with active MDR-TB HIV co-morbidity: insights from a strain with a unique genomic deletion.

Coinfection of HIV and multidrug-resistant tuberculosis (MDR-TB) presents significant challenges in terms of the treatment and prognosis of tuberculosis, leading to complexities in managing the disease and impacting the overall outcome for TB patients. This study presents a remarkable case of a patient with MDR-TB and HIV coinfection who survived for over 8 years, despite poor treatment adherence and comorbidities. Whole genome sequencing (WGS) of the infecting () strain revealed a unique genomic deletion, spanning 18 genes, including key genes involved in hypoxia response, intracellular survival, immunodominant antigens, and dormancy.

Genomic, phenotypic and demographic characterization of in Israel in 2021.

According to World Health Organization WHO, Tuberculosis (TB) is the second cause of death from infectious disease worldwide. During 2021, 10.6 million people were infected with TB, and 1.

Emergence of Mycobacterium canariasense infections in central Israel.

In 2018, Mycobacterium canariasense bloodstream infection was diagnosed in Israel. Further investigation had identified additional five cases in three medical centers, including isolates from blood (1), cornea (1), and sputum (3). Isolates were susceptible to all the antimicrobial tested.

from Cardio Surgery Heating-Cooling Units and from Clinical Samples in Israel Are Genetically Unrelated.

Non-tuberculous mycobacteria (NTM) are opportunistic pathogens that cause illness primarily in the elderly, in the immunocompromised or in patients with underlying lung disease. Since 2013, a global outbreak of NTM infection related to heater-cooler units (HCU) used in cardio-thoracic surgery has been identified. This outbreak was caused by a single strain of .

Mycobacterium gordonae infecting redclaw crayfish Cherax quadricarinatus.

The redclaw crayfish Cherax quadricarinatus (von Martens, 1868) is one of the most commonly exploited freshwater crayfish species worldwide. Redclaw crayfish are susceptible to a number of pathogens but none have been linked to widespread epizootics. Mycobacterial infections have been sporadically reported in crayfish.

Structure and variation of CRISPR and CRISPR-flanking regions in deleted-direct repeat region Mycobacterium tuberculosis complex strains.

Background: CRISPR and CRISPR-flanking genomic regions are important for molecular epidemiology of Mycobacterium tuberculosis complex (MTBC) strains, and potentially for adaptive immunity to phage and plasmid DNA, and endogenous roles in the bacterium. Genotyping in the Israel National Mycobacterium Reference Center Tel-Aviv of over 1500 MTBC strains from 2008-2013 showed three strains with validated negative 43-spacer spoligotypes, that is, with putatively deleted direct repeat regions (deleted-DR/CRISPR regions). Two isolates of each of three negative spoligotype MTBC (a total of 6 isolates) were subjected to Next Generation Sequencing (NGS).

Mycobacterium szulgai chronic multifocal osteomyelitis in an adolescent with inherited STAT1 deficiency.

We report a 17-year-old patient with inherited STAT1 deficiency, who was diagnosed with Mycobacterium szulgai chronic multifocal osteomyelitis and responded well to the therapy with ethambutol, rifampicin and azithromycin. Seven other reported cases of M. szulgai osteomyelitis are reviewed.

Polymorphic exact tandem repeat A (PETRA): a newly defined lineage of mycobacterium tuberculosis in israel originating predominantly in Sub-Saharan Africa.

As part of the Israel National Program for Prevention and Control of Tuberculosis, the molecular epidemiology of new tuberculosis cases is monitored. Prospective screening showed that about 20% of all new cases of culture-positive tuberculosis (43 of 222) in Israel in the year 2008 were caused by certain Mycobacterium tuberculosis strains of the central Asian (CAS) spoligotype lineage. The identity and similarity of these strains by mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-VNTR) typing form a lineage we call PETRA for polymorphic at locus ETR A.
