Summary: Avian pathogenic Escherichia coli (APEC) is a severe issue to both poultry business and public health. This study focused on the isolation of E. coli from diseased broiler chickens and investigated their antimicrobial resistance and biofilm forming capacity. Phages were also studied to determine their presence in E. coli isolates and their ability to inhibit and dissolve biofilms. The results showed that phage therapy could be an attractive option for preventing and controlling multidrug resistant colibacillosis in broilers.

Summary: Biofilms are a crucial mode of growth for bacteria, but how antibiotic resistance emerges and is selected in biofilms is poorly understood. This study developed and validated a microfluidic chip (Brimor) for studying the dynamics of antibiotic-resistant bacteria in biofilms. The chip was found to be easy to use and a relevant model for studying the selection of antibiotic resistance in bacterial biofilms, providing valuable insights into this area of research.

Summary: The study evaluated the geospatial spread and antibiotic-resistant relatedness of Escherichia coli O157 in southwest Nigeria, which is an important virulent serotype causing severe complications. The results showed that human strains of stx-encoded Escherichia coli O157 were more prevalent compared to water and food animal strains, and exhibited high conjugative and transformative activity. The strains also displayed resistance to several common antibiotics. Analysis of the strains from different sources revealed similar biological characteristics and resistance patterns. The study highlights the importance of implementing One Health approach and population-target antimicrobial stewardship to mitigate the spread of antibiotic-resistant Escherichia coli O157 and reduce its impact on intestinal morbidity and mortality.

Summary: A strategy to simultaneously remove Escherichia coli O157 and its biofilms was successfully developed using composite nanofiber films. The films, synthesized by encapsulating E. coli O157 phages and D-phenylalanine into sodium alginate/polyethylene oxide nanofibers, showed excellent antibacterial activity against both free E. coli O157 and biofilms. The addition of D-phenylalanine significantly enhanced the inhibitory activity against E. coli O157 proliferation and biofilm formation during short-term storage of beef and fruits and vegetables.

Summary: Fish is an important part of Bengali cuisine and economy, but it can also be a potential source of pathogens. This study investigated the distribution of Enterococcus faecalis in wild and cultivated fish in Bangladesh, finding that wild fish had a higher frequency of virulence genes and biofilm-forming genes, while cultivated fish carried more highly multidrug resistant strains.

Summary: This study systematically characterized E. coli O157:non-H7 strains isolated from retail food in Chinese markets. The strains displayed diverse H serotypes, virulence genes, and antibiotic resistance. Some strains also harbored plasmid-mediated colistin-resistant genes, which is a significant concern.

Summary: The emergence of antibiotic-resistant bacteria poses a serious challenge to human, animal, and environmental health worldwide. A study in Japan found that antibiotic-resistant E. coli was prevalent in Lake Biwa and inflow rivers, with similar resistance patterns to clinical samples. The numbers of antibiotic-resistant E. coli decreased during wastewater treatment processes, but the resistance rates increased, suggesting selection for antibiotic resistance during treatment.

Summary: The study assessed the prevalence of enterococci in pasteurized milk samples from retail stores in Northwest Iran, finding that most isolates were identified as E. faecalis or E. faecium, carrying various virulence genes and showing high resistance to most antibiotics tested. Additionally, the isolates were able to produce biofilm, suggesting that pasteurized milk could potentially transmit multidrug-resistant virulent enterococci strains to humans.

Summary: This study investigated the prevalence of Aliarcobacter spp. in edible internal organs of different animal species and analyzed their antimicrobial resistance, virulence profiles, biofilm-forming capabilities, and phylogenetic relationships. The results showed a relatively high detection rate of Aliarcobacter spp., predominantly A. butzleri and A. cryaerophilus, with most isolates exhibiting multidrug resistance and weak biofilm formation. The presence of pathogenic and multidrug-resistant Aliarcobacter spp. in food poses a potential risk to public health and control measures are necessary to prevent the spread of these strains.

Summary: This study investigated the prevalence of Toxoplasma gondii in raw milk and cheese from different animal species in Kayseri Province, Turkiye, using real-time PCR. The study found that T. gondii DNA was present in 8% of sheep raw milk samples, 4% of goat raw milk samples, and none of the cheese samples. These results suggest that the presence of T. gondii DNA in raw milk samples sold in Kayseri Province may pose a risk to public health.

Summary: This study investigated the genetic diversity, prevalence, and mechanisms of resistance to quinolone antibiotics in 178 Campylobacter jejuni isolates from humans, cattle, dogs, and chickens in Turkey. The results showed that there were 21 clonal complexes (CCs) and 78 different sequence types (STs) among the isolates, with CC21, CC353, CC206, and CC257 being the predominant clones. Quinolone resistance was detected in 41% of the isolates, and all resistant isolates had a specific mutation in the gyrA gene. The study provided important insights into the transmission pathways of C. jejuni in Turkey, suggesting that broiler meat and dogs may be the most important sources of human campylobacteriosis in the country.

Summary: This study investigated the effects of Shiitake mushroom supplementation on live weight, feed consumption, blood serum biochemical parameters, and intestine bacteria populations in quails. The results showed that Shiitake mushroom supplementation had significant effects on live weight, feed conversion ratio, and blood serum glucose levels. However, it had no significant effects on feed consumption, blood serum total protein, total cholesterol, triglyceride levels, and intestine bacteria populations. Increasing Shiitake mushroom supplementation ratios worsened the growth performance of quails.
