Dynamic Challenges of Active Tuberculosis: Prevalence and Risk Factors of Co-Infection in Clinical and Microbiological Characteristics at King Abdulaziz University Hospital, Jeddah, Saudi Arabia.

Background: Tuberculosis (TB) is a major public health issue in Saudi Arabia, particularly impacting the elderly. Immunocompromising conditions, including comorbidities, malignancies, and the use of immunosuppressive agents, are major risk factors for active TB (ATB).

Objective: To analyze clinical factors and estimate mortality in TB and drug-resistant cases.

Noncontiguous finished genome sequence and description of Raoultibacter massiliensis gen. nov., sp. nov. and Raoultibacter timonensis sp. nov, two new bacterial species isolated from the human gut.

As part of the culturomics project aiming at describing the human microbiota, we report in this study the description of the new bacterial genus Raoultibacter gen. nov. that includes two new species, that is, R.

Infectious Agents and Neurodegenerative Diseases: Exploring the Links.

Recent studies have shown that bacterial and viral infections are risk factors for various neurodegenerative diseases such as Amyotrophic lateral sclerosis (ALS), Multiple Sclerosis (MS), Alzheimer's disease (AD), and Lyme disease (LD). However, it is still controversial how the infections play a role in neurological diseases progression. Infections in central nervous system may lead multiple damages in infected and neighboring cells.

Microbial Culturomics to Map Halophilic Bacterium in Human Gut: Genome Sequence and Description of Oceanobacillus jeddahense sp. nov.

Culturomics is a new omics subspecialty to map the microbial diversity of human gut, coupled with a taxono-genomic strategy. We report here the description of a new bacterial species using microbial culturomics: strain S5T, (= CSUR P1091=DSM 28586) isolated from a stool specimen of a 25-year-old obese patient from Saudi Arabia. The strain S5T was a Gram-positive, strictly aerobic rod, which was motile by a polar flagellum, spore-forming, and exhibited catalase and oxidase activities.

Rise of Microbial Culturomics: Noncontiguous Finished Genome Sequence and Description of Beduini massiliensis gen. nov., sp. nov.

Microbial culturomics is a new field of omics sciences that examines the bacterial diversity of human gut coupled with a taxono-genomic strategy. Using microbial culturomics, we report here for the first time a novel Gram negative, catalase- and oxidase-negative, strict anaerobic bacilli named Beduini massiliensis gen. nov.

Genome sequence of Oceanobacillus picturae strain S1, an halophilic bacterium first isolated in human gut.

Oceanobacillus picturae is a strain of a moderately halophilic bacterium, first isolated from a mural painting. We demonstrate, for the first time, the culture of human Oceanobacillus picturae, strain S1(T), whose genome is described here, from a stool sample collected from a 25-year-old Saoudian healthy individual. We used a slightly modified standard culture medium adding 100 g/L of NaCl.

Non-contiguous finished genome sequence and description of Corynebacterium jeddahense sp. nov.

Corynebacterium jeddahense sp. nov., strain JCB(T), is the type strain of Corynebacterium jeddahense sp.
