Background: Urinary tract infections are frequently caused by Gram-negative bacilli, and timely detection and management of resistant strains and their antimicrobial susceptibilities are crucial.
Methods: A six-month study examined Gram-negative bacilli from catheterized and noncatheterized patients, assessing antibiotic susceptibility, minimum inhibitory concentration, and Extended spectrum beta lactamase (ESBL) production genes using real-time Polymerase chain reaction (PCR).
Results: Out of 72 isolates, 55.56% were ESBLs, with 65.0% from catheterized and 35.0% from noncatheterized samples. Out of 21 ESBL isolates, 47.62% had cefotaximase M (CTX-M) gene, while 4.76% had sulfhydril variant (SHV) and oxacillinase (OXA) 10/11 genes. Coproduction of CTX-M and SHV was observed.
Conclusion: The study reveals multiple ESBL genes co-expression in clinical isolates from catheterized and noncatheterized patients, emphasizing the need for regular monitoring and antibiotic policy development.

This study synthesized eighteen phenyl and furan rings containing thiazole Schiff base derivatives 2(a-r) in five series, and spectral analyses confirmed their structures. The in vitro antibacterial activities of the synthesized analogs against two gram-positive and two gram-negative bacteria were evaluated by disk diffusion technique. Compounds (2d) and (2n) produced prominently high zone of inhibition with 48.

Iron reduction in paddy fields is crucial for heavy metal migration and nutrient transformation. Gram-negative iron-reducing bacteria like Geobacter and Shewanella have been widely studied due to their strong extracellular electron transfer capabilities. In contrast, Gram-positive bacteria such as Bacillus and Clostridium are often labeled as weak exoelectrogens, leading to their contributions being overlooked.

Background And Objectives: Carbapenem-resistant Gram-negative bacilli (CRGNB), especially and , are critical pathogens associated with excess morbidity and mortality. To elucidate their molecular epidemiology and clinical outcomes in Japan, patients with CRGNB were enrolled in the MDR organisms clinical research network (MDRnet) consisting of eight tertiary care facilities.
Methods: Between 2019 and 2022, 246 unique patients with carbapenem-resistant (CRE), carbapenem-resistant (CRPA) and carbapenem-resistant (CRAB) isolates were prospectively enrolled.
