Shiga toxin-producing Escherichia coli (STEC) is an important causal agent of food borne diseases. Although the presence of STEC has been reported in cattle, goat, and sheep in previous studies in Bangladesh, there is seemingly no information on sorbitol non-fermenting STEC (SN-F STEC) carriage in buffalo. We aimed to assess the prevalence of SN-F STEC and to identify common virulence genes in SN-F STEC strains from apparently healthy buffaloes on smallholdings in coastal area in Bangladesh. Total 308 buffaloes on smallholdings in Patenga and Anwara Upazila, Chattogram division, Bangladesh were randomly sampled by collecting a swab from the recto-anal junction …


Multidrug Resistant Escherichia Coli Harboring Extendedspectrum Β-Lactamase-Encoding Genes Isolated From Clinically Healthy Pigs, Khin Khin Lay, Haidee E. Torio, Asinamai Athliamai Bitrus, Wanida Mala, Nuananong Sinwat, Rungtip Chuanchuen Jun 2021

Multidrug Resistant Escherichia Coli Harboring Extendedspectrum Β-Lactamase-Encoding Genes Isolated From Clinically Healthy Pigs, Khin Khin Lay, Haidee E. Torio, Asinamai Athliamai Bitrus, Wanida Mala, Nuananong Sinwat, Rungtip Chuanchuen

The Thai Journal of Veterinary Medicine

A total of 292 E. coli isolates obtained from fecal samples from pigs in Central (n = 103) and Northeastern (n = 189) provinces of Thailand were included in this study. Eighty-six E. coli isolates were phenotypically confirmed to be β- lactamases producers and screened for the presence of β-lactamase genes. The CTX-M family was most frequently identified (90.7%). The blaCTX-M-15 gene belonging to CTX-M group I (59.3%) was the most predominantly identified CTX-M genotype followed by blaCTX-M-14 (31.4%) and blaCTX-M-4 (25.6%). The blaTEM-1 gene was prevalent (75.6%). The blaCTX-M-4 and blaCTX-M-14 genes were located on conjugative plasmid. The results …


Retrospective Analysis Of The Incidence, Aetiology And Risk Factors Of Sepsis Based On Post-Mortem Examination Records In Ruminants, Batrisyia Syazana Faridon, Mohd Zamri-Saad, Annas Salleh Jun 2021

Retrospective Analysis Of The Incidence, Aetiology And Risk Factors Of Sepsis Based On Post-Mortem Examination Records In Ruminants, Batrisyia Syazana Faridon, Mohd Zamri-Saad, Annas Salleh

Sepsis is an important disease in both humans and animals. In animals, it is usually caused by septicaemia after infection and has not been well-studied. This article describes a retrospective analysis of sepsis cases in small and large ruminants submitted to the Post-Mortem Laboratory, Faculty of Veterinary Medicine, Universiti Putra Malaysia between the years 2007 and 2017. The incidence of sepsis was found to be at 40.5% in small ruminants and 38.6% in large ruminants. In both small and large ruminants, sepsis was mainly caused by bacterial infection, which was significantly (p<0.05) higher compared to parasitic and viral infections. Most cases of sepsis occur due to infections originating from the gastrointestinal tract and this is followed by the respiratory tract. Escherichia coli has been found to be the most common bacterial pathogen of sepsis in ruminants; significantly (p<0.05) higher compared to other bacterial pathogens like Klebsiella pneumoniae, Pasteurella sp., and Staphylococcus aureus. Sepsis involving E. coli has often resulted in pure isolation of the pathogen, thus being suggestive of a single infection. Underlying or concurrent infection is the most important risk factor leading to sepsis in ruminants, with significant difference (p<0.05) compared to other risk factors such as stress or malnutrition. Associations between the gastrointestinal system as the point of entry and sepsis caused by either E. coli or K. pneumoniae have been noted. This study provides an insight into a basic understanding of sepsis in ruminants.


Identification Of Genotype And Phenotype Of Antimicrobial Resistance Of Escherichia Coli Isolates From Pigs In Southern Vietnam, Do Tien Duy, Nguyen Luong Lam Anh, Nguyen Thi Kim Thoa, Phitsanuwattana K, Thongratsakul S, Carrique-Mas Jj, Le Thanh Hien, Nguyen Thi Thu Nam, Nguyen Tat Toan Mar 2021

Escherichia coli is a primary reservoir of antimicrobial resistance, known chiefly for the container of AMR-encoding genes (ARGs), and poses potential risks to human and animal health. This study investigated AMR phenotypes and ARGs in 90 E. coli isolates from different pig groups in 10 farms in southern Vietnam. The minimum inhibitory concentration (MIC) of 19 common antimicrobial agents was determined, and polymerase chain reaction (PCR) was used to investigate seven ARGs (blaTEM, aadA1, strA, dfrA12, sul3, cmlA and tetA). Cohen’s kappa statistic (κ) was applied to assess the concordance between phenotypic and genotypic profiles. A total of 81.1% of …
