Pathogenicity of the avian Escherichia coli isolates from pericarditis and femoral head necrosis lesions of the colibacillosis in experimentally infected chicks

Indian Journal of Animal Sciences, 2019
The aim of the present study was to evaluate the relationship between different combinations of seven (ompT, hlyF, iss, iutA, iroN, tsh and cvaC) Colicin V (ColV) plasmid associated virulence genes (VGs) and pathogenicity of avian E. coli isolates. After

Unravelling the Pathotype, Biofilm, Virulome and Resistome Profile of MultiDrug‐Resistant Bacteria Isolated From Cattle Faeces Using Whole Genome Sequence Analysis

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
The high mortality and morbidity resulting from diarrhoeal cases worldwide are associated with the increasing incidence of antimicrobial resistance (AMR) and represent a serious public health concern. Cattle are a major reservoir of AMR organisms, and faecal shedding may facilitate their transmission into the food chain.

Role of tol genes in cloacin DF13 susceptibility of Escherichia coli K-12 strains expressing the cloacin DF13-aerobactin receptor IutA

Journal of Bacteriology, 1993
IutA is the outer membrane protein receptor for ferric aerobactin and the bacteriocin cloacin DF13. Although the same receptor is shared, ferric aerobactin transport across the outer membrane in Escherichia coli is TonB dependent, whereas cloacin DF13 transport is not. We have recently observed that tolQ is required for cloacin DF13 susceptibility (J.A.

Antimicrobial Resistance, Virulence, and Genomic Characteristics of Klebsiella pneumoniae Isolated From Four Host Sources in Northeast China

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Klebsiella pneumoniae is an important emerging pathogen leading to serious clinical outcomes as the multidrug‐resistant (MDR) isolates arise. While K. pneumoniae is a well‐known pathogen in human clinical settings, its risks in nonhuman hosts and potential for cross‐species transmission remain poorly understood. In this study, we performed whole‐genome

An analytical model to predict the mass loading of air cleaners in typical indoor environments and to estimate the service interval from standardized filter loading tests

Indoor Environments
For indoor air cleaners, especially those using electret filters, it is known that the clean air delivery rate (CADR) can strongly decrease over time due to loading of the filters with particles.
