The study aimed to examine the prevalence and genetic characteristics of ESBL-production and colistin resistance in and from pigs and pork in the border area among Thailand, Cambodia, Lao PDR, and Myanmar. ( = 463) and ( = 767) isolates were collected from pig rectal swab from slaughterhouses ( = 441) and pork from retail markets ( = 368) during October 2017 and March 2018. All were determined for susceptibility to colistin and cephalosporins, ESBL production and and ESBL genes. was predominantly found in Cambodia (65.8%). Serovars Rissen (35.6%) and Anatum (15.3%) were the most common. The prevalence in pork was above 91% in all countries. Colistin-resistance rate in (10.4%) was significantly higher than (2.6%). ESBL-producing (1.9%) and (6.3%) were detected. The and were identified. The gene was detected in ( = 12) and ( = 68). The / and / co-concurrence was observed in one and three isolates, respectively. In conclusion, pigs and pork serve as carriers of colistin and new generation cephalosporins resistance. Testing for resistance to last line antibiotics should be included in national AMR surveillance program using One Health approach.

African swine fever virus is highly contagious and causes a fatal infectious disease in pigs, resulting in a significant global impact on pork supply. The African swine fever virus RNA polymerase serves as a crucial multifunctional protein complex responsible for genome transcription and regulation. Therefore, it is essential to investigate its structural and functional characteristics for the prevention and control of African swine fever.

Raw pork is prone to oxidation and rancidity as it contains a high level of unsaturated lipid molecules. Reliable biomarkers to benchmark pork freshness and their formation have not been systematically investigated. The results indicated that the peroxide values, TVB-N and rancid volatiles dramatically increased in pork during the storage period (4 °C, 0-9 d).

is a zoonotic pathogen that causes invasive infections in humans who have been in close contact with infected pigs or contaminated pork-derived products. There is currently no consensus on the universal virulence factors or markers that can differentiate pathogenic from non-pathogenic or commensal isolates. A diagnostic tool for serotyping and pathotyping of is required for active public health surveillance and the One-Health approach.

The spread of African swine fever virus (ASFV) has led to major economic losses to pork worldwide. In Russia, there are no developed or registered vaccines against ASFV genotype II, which is associated with numerous ASFV outbreaks in populations of domestic pigs and wild boars in the country. We introduced deletions of the six MGF360 and MGF505 genes of the ASFV virulent Stavropol_01/08 strain, isolated in Russia in 2008.

Pen-based oral fluids are used extensively for surveillance and disease detection in swine, but there is sparse information on the sampling process itself. To address this shortcoming, we documented the pen-based oral fluid sampling process with the aim of optimizing the number of pigs in a pen that contributed to the sample. We quantified the effects of (1) previous experience with rope sampling (training), (2) the number of ropes suspended in the pen, and (3) sampling time on pig participation and pig-rope contact.
