This study investigated the occurrence of Escherichia coli O157:H7 and Salmonella spp. and their antimicrobial susceptibility from ducks and indigenous chickens in major live-bird markets at Ibadan, Oyo State, Nigeria. Thirty-one cloacae samples were each collected from both ducks and indigenous chickens in three different sample locations for a total of 186 cloacae swab samples. Isolation of Escherichia coli (E. coli) was done using MacConkey agar and Sorbitol MacConkey agar selective for E. coli O157:H7, while serological latex agglutination test kit was used to confirm isolates. Rappaport Vassiliadis and Xylose Lysine Deoxycholate agar were used for Salmonella spp. Antibiotic susceptibility was determined using the disc diffusion method and interpreted using the CLSI 2020 standards. Data were analyzed using descriptive statistics and Fisher's exact test (p ≤ 0.05). Escherichia coli O157:H7 was confirmed in 31 samples (16.7%). E. coli isolates showed high resistance (90.3-93.5%) to cefuroxime, cefixime, ceftazidime, and amoxicillin, while they were highly susceptible to ofloxacin (96.8%) and gentamycin (80.7%). Salmonella was confirmed in 24 samples (12.9%). Salmonella showed 100% resistance to cefuroxime, cefixime ceftazidime, and amoxicillin, but was highly susceptible to gentamycin (91.7%) and nitrofurantoin (66.7%). No statistically significant association (p<0.05) was observed between the occurrence of E. coli O157 and Salmonella within the three live-bird markets. This study reveals that E. coli and Salmonella spp. occur in ducks and indigenous chickens from major live bird markets in Ibadan, Oyo state with antimicrobial susceptibility. Findings from this study underscores the need for further studies on these pathogenic organisms from ducks in Nigeria because there is paucity of data on this species of poultry that may serve as reservoir for these zoonotic organisms.

Escherichia coli has become a common causative agent of infections in animals, inflicting serious economic losses on livestock production and posing a threat to public health. Escherichia coli infection is common and tends to be complex in Xinjiang, a major region of cattle and sheep breeding in China. This study aims to explore the current status and molecular characteristics of Escherichia coli infection in cattle and sheep in Xinjiang, as part of the disease prevention and control strategy.

Background: Liver transplantation (LT) is a critical intervention for individuals with end-stage liver disease; yet, post-transplant problems, especially infections, graft rejection, and chronic liver disease, are often linked to systemic inflammation. Cytokines, small signaling molecules, significantly influence immune responses during and post-liver transplantation. Nonetheless, the intricate relationships among cytokines, immune responses, and the gut microbiota, especially gut dysbiosis, are still inadequately comprehended.

We have previously developed a transcription-based bacterial three-hybrid (B3H) assay as a genetic approach to probe RNA-protein interactions inside of E. coli cells. This system offers a straightforward path to identify and assess the consequences of mutations in RBPs with molecular phenotypes of interest.

Azurin, a bacterial blue-copper protein, has garnered significant attention as a potential anticancer drug in recent years. Among twenty Pseudomonas aeruginosa isolates, we identified one isolate that demonstrated potent and remarkable azurin synthesis using the VITEK 2 system and 16S rRNA sequencing. The presence of the azurin gene was confirmed in the genomic DNA using specific oligonucleotide primers, and azurin expression was also detected in the synthesized cDNA, which revealed that the azurin expression is active.
