Three hundred and fifteen patients with chronic nonulcerative colitis were studied. Two hundred patients were given specific immunotherapy by bacterial allergens, and 115 formed the control group. Immunotherapy was carried out with increasing doses of bacterial allergens - E Coli, Streptococcus, Staphylococcus or Proteus - for 1-2 years. The effectiveness of immunotherapy was established toward the end of the course of treatment (as well as over a long period). The improvement was expressed clinically as a decrease in the endoscopic and coprologic signs of inflammation, an increase in natural immunologic resistance and a reduction of bacterial allergy and autoimmune disorders.

Wastewater treatment plant (WWTP) workers are exposed to bioaerosols containing bacteria, fungi, and endotoxin, potentially posing health risks to workers. This study quantified personal exposure levels to airborne bacteria and fungi, endotoxin, and dust among 44 workers during two seasons at four WWTPs. Associations between the exposure measurements and serum levels of biomarkers CRP, SAA, and CC16 were also assessed.

Streptococcus pneumoniae (SPN) is a significant pathogen causing pneumonia and meningitis, particularly in vulnerable populations like children and the elderly. Available pneumonia vaccines have limitations since they only cover particular serotypes and have high production costs. The emergence of antibiotic-resistant SPN strains further underscores the need for a new, cost-effective, broad-spectrum vaccine.

is a gram-negative, facultatively anaerobic bacterium typically found in the oropharynx and respiratory tract of humans. It is responsible for various infections, including head-and-neck infections, pericarditis, and abscesses of the deltoid, perirenal tissue, brain, and liver. Increasing antibiotic resistance requires urgent identification of novel drug targets to fight this bacterium.

Rationale: It is imperative to be cautious about the potential systemic allergic reaction caused by the combined use of Qing Kailing Injection (QKI) and clindamycin as it may be life-threatening.
Patient Concerns: A 48-year-old female with a history of hypertension was admitted to a private hospital with a fever and cough. She was diagnosed with lung infection and received QKI infusion, followed by clindamycin infusion.

Bacterial sRNAs together with the RNA chaperone Hfq post-transcriptionally regulate gene expression by affecting ribosome binding or mRNA stability. In the human pathogen , the causative agent of whooping cough, hundreds of sRNAs have been identified, but their roles in biology are mostly unknown. Here we characterize a Hfq-dependent sRNA (S17), whose level is dramatically higher in the virulence (Bvg) mode.
