Mutational and transcriptional analyses of an avian pathogenic Escherichia coli ColV plasmid [PDF]

BMC Microbiology, 2008
Abstract Background Previously we described a 184-kb ColV plasmid, pAPEC-O2-ColV, that contributed to the ability of an E. coli to kill avian embryos, grow in human urine, and colonize the murine kidney. Here, the roles of several genes encoded by this plasmid in virulence were assessed using mutational and ...

Extended-Spectrum Beta-Lactamase Producing Strains of Escherichia Coli Isolated from Avian Cellulitis Lesions [PDF]

Brazilian Journal of Poultry Science
Avian cellulitis causes significant losses to the poultry industry. Avian-pathogenic Escherichia coli (APEC) is the etiological agent of that disease. This microorganism has zoonotic potential and may act as reservoir of antimicrobial-resistance genes ...

Effects of Lactobacillus Alone and in Combination With Saccharomyces as Alternatives to Antibiotics on Performance and Immunity in Laying Hens

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Supplementation with Lactobacillus plantarum alone or combined with Saccharomyces cerevisiae improved laying performance, egg quality, immune response and caecal microbial balance by increasing beneficial lactic acid bacteria and reducing coliforms, demonstrating probiotics as a safe and sustainable alternative to antibiotic growth promoters in ...

In vitro antibiofilm activity of resveratrol against avian pathogenic Escherichia coli

BMC Veterinary Research, 2021
Background Avian pathogenic Escherichia coli (APEC) strains cause infectious diseases in poultry. Resveratrol is extracted from Polygonum cuspidatum, Cassia tora Linn and Vitis vinifera, and displays good antimicrobial activity.

A Safe and Effective Bivalent Vaccine Candidate Against Duck Enteritis Virus and Duck‐Origin Novel Goose Parvovirus

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
NGPV VP2 is expressed made DEV as vector and experessed NGPV VP2 could form virus‐like particles. rNGPV VP2‐Cre could facilitate clearance of NGPV and provided strong protection against highly virulent DEV. ABSTRACT Since 2015, duck‐origin novel goose parvovirus (NGPV) has caused severe economic losses to the Chinese duck industry, with no licensed ...

Using Ongoing Wildlife Surveillance Programs to Monitor Antibiotic Resistant Bacteria in the Environment

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Screening of ESBL‐, pAmpC‐ and carbapenemase‐producing Escherichia coli among Swedish wildlife demonstrated a low occurrence of antibiotic resistance in wild animals. Only two ESBL/pAmpC‐producers were detected in red foxes originating from highly populated areas.

Safety and efficacy of a feed additive consisting of nicarbazin (NICACOX®) for chickens for fattening and chickens reared for laying (Huvepharma N.V.)

EFSA Journal, Volume 24, Issue 8, August 2026.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a feed additive consisting of nicarbazin (NICACOX®) as a coccidiostat for chickens for fattening and chickens reared for laying.
