Escherichia coli and isolates produce a range of different polysaccharide structures that play important roles in their biology. E. coli isolates often possess capsular polysaccharides (K antigens), which form a surface structural layer. These possess a wide range of repeat-unit structures. In contrast, only one capsular polymer (Vi antigen) is found in , and it is confined to typhoidal serovars. In both genera, capsules are vital virulence determinants and are associated with the avoidance of host immune defenses. Some isolates of these species also produce a largely secreted exopolysaccharide called colanic acid as part of their complex Rcs-regulated phenotypes, but the precise function of this polysaccharide in microbial cell biology is not fully understood. E. coli isolates produce two additional secreted polysaccharides, bacterial cellulose and poly--acetylglucosamine, which play important roles in biofilm formation. Cellulose is also produced by Salmonella isolates, but the genes for poly--acetylglucosamine synthesis appear to have been lost during its evolution toward enhanced virulence. Here, we discuss the structures, functions, relationships, and sophisticated assembly mechanisms for these important biopolymers.

An enteroinvasive Escherichia coli (EIEC) outbreak affecting 154 individuals was identified among attendees at a wedding in Loei Province, Thailand. The median time to symptom onset was 18 h (range: 7-72 h). The epidemiological evidence suggested that larb-neua-dib (spicy minced raw beef salad) was the probable source of the outbreak.

Avian pathogenic (APEC) is one of the major causes of poultry morbidity worldwide, severely reducing egg production and embryo hatchability in laying hens. Hainan Wenchang chicken is an important poultry breed in Hainan, China, and its culture has been affected by APEC for a long time. In this study, in order to investigate the causes of low hatchability and a large number of weak chicks during the breeding of Wenchang chicken, a total of 130 strains of APEC were isolated from 591 chicken embryo samples collected from five large-scale farms of Wenchang chicken in Hainan area.

() serves as a critical indicator microorganism for assessing the prevalence and dissemination of antibiotic resistance, notably harboring various antibiotic-resistant genes (ARGs). Among these, the emergence of the gene represents a significant threat to public health, especially since carbapenem antibiotics are vital for treating severe infections caused by Gram-negative bacteria. This study aimed to characterize the antibiotic resistance features of -positive strains isolated from waterfowl in several regions of China and elucidate the dissemination patterns of the gene.

Background: Amid the COVID-19 pandemic, the surge in hospital admissions and widespread use of broad-spectrum antibiotics have heightened the risk of hospital-acquired infections from multidrug-resistant (MDR) organisms, particularly . It is imperative to implement stringent measures to curb the spread of antimicrobial resistance in hospitals and devise robust treatment strategies for patients grappling with such infections. To confront this challenge, a comprehensive study was undertaken to examine MDR extended-spectrum beta-lactamase (MDR-ESBL)-producing isolates from patients with nosocomial infections following the COVID-19 pandemic in Northern Iran.

Background: Patients with tuberculosis (TB) often harbor diverse bacteria in their sputum, including both commensal and opportunistic pathogens. This study aimed to characterize the sputum microbiota of TB patients before and after the intensive phase of anti-TB treatment and assess changes in bacterial diversity and antibiotic resistance profiles.
Methods: A total of 162 patients with TB (128 males, 34 females; age range 18-82 years) provided sputum samples at baseline, of which 72 provided follow-up sputum after two months of intensive phase treatment.
