Dissimilar ruminal epithelial response to short-term and continuous intraruminal infusion of sodium n-butyrate.

Abstract: Summary Two ewes were given 2 g/kg body weight/day of sodium n-butyrate through a rumen fistula in two different ways for 9 days. Continuous infusion of butyrate caused a decrease in ruminal epithelial cell proliferation. Histologically, a thickening of the stratum corneum was observed. Daily short-term infusions produced stimulation of ruminal epithelial cell proliferation. Histological examination revealed parakeratotic changes in the stratum corneum. Zusammenfassung Unterschiedliche Reaktionen des Pansenepithels nach kurzfristiger und kontinuierlicher intraruminaler Infusion von Natrium-n-Butyrat Zwei Schafe erhielten wahrend 9 Tagen uber eine Pansenfistel je 2 g Natrium-n-Butyrat/kg KGW/Tag auf unterschiedliche Art verabreicht. Die kontinuierliche Infusion von Butyrat fuhrte zu einer Reduktion der Zellproliferation im Pansenepithel. Histologisch konnte eine Verdickung des Stratum corneum beobachtet werden. Tagliche kurzfristige Infusionen stimulierten die Zellproliferation im Pansenepithel. Die histologische Untersuchung ergab parakeratotische Veranderungen im Stratum corneum. Resume Reactions differentes de l'epithelium de la panse apres une infusion breve et continue dans le Rumen de sodium-n-butyrate Deux moutons ont recu pendant 9 jours 2 g de sodium-n-butyrate/kg de poids par une fistule de la panse. L'infusion continue de butyrate a provoque une diminution de la proliferation cellulaire dans l'epithelium de la panse. Un epaississement de Stratum corneum a ete observe a l'histologie. Des infusions breves journalieres stimulerent la proliferation cellulaire dans l'epithelium de la panse. L'examen histologique a montre des lesions de parakeratose dans Stratum corneum. Resumen Respuestas disimiles del epitelio ruminal a la infusion intrarruminal a corto plazo y a la continua de butirato-n sodico Cada una de dos ovejas recibieron durante 9 dias, a traves de una fistula, 2g de butirato-n sodico/kg peso en vivo/dia administrados de forma diferente. La infusion continua de butirato conducia a la reduccion de la proliferacion celular en el epitelio de la panza. Histologicamente se pudo observar el espesamiento del estrato corneo. Las infusiones diarias a corto plazo producian estimulacion de la proliferacion celular en el epitelio ruminal. El examen histologico revelo cambios paraqueratoticos en el estrato corneo.

Colistin Resistance and ESBL Production in Salmonella and Escherichia coli from Pigs and Pork in the Thailand, Cambodia, Lao PDR, and Myanmar Border Area.

Abstract: The study aimed to examine the prevalence and genetic characteristics of ESBL-production and colistin resistance in Salmonella and Escherichia coli from pigs and pork in the border area among Thailand, Cambodia, Lao PDR, and Myanmar. Salmonella (n = 463) and E. coli (n = 767) isolates were collected from pig rectal swab from slaughterhouses (n = 441) and pork from retail markets (n = 368) during October 2017 and March 2018. All were determined for susceptibility to colistin and cephalosporins, ESBL production and mcr and ESBL genes. Salmonella was predominantly found in Cambodia (65.8%). Serovars Rissen (35.6%) and Anatum (15.3%) were the most common. The E. coli prevalence in pork was above 91% in all countries. Colistin-resistance rate in E. coli (10.4%) was significantly higher than Salmonella (2.6%). ESBL-producing Salmonella (1.9%) and E. coli (6.3%) were detected. The blaCTX-M-55 and blaCTX-M-14 were identified. The mcr-1 gene was detected in Salmonella (n = 12) and E. coli (n = 68). The mcr-1/blaCTX-M-55 and mcr-3/blaCTX-M-55 co-concurrence was observed in one Salmonella and three E. coli 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.

Morphological and Molecular Characterization of Explanatum Explanatum from Cattle and Buffaloes in Myanmar

Abstract: A robust molecular marker is needed for discrimination of amphistome species, because identification based on morphology alone requires specialized knowledge and techniques. In this study, we performed morphological and molecular characterization of Explanatum explanatum, a species that causes severe liver damage in definitive host species. Fifty-five adult amphistomes were collected from cattle and water buffaloes in Myanmar. Eighteen of the amphistomes, arbitrarily chosen, were morphologically identified as E. explanatum using sagittal sections. All of the 55 amphistome isolates had identical second internal transcribed spacer (ITS2) of ribosomal DNA sequences; these sequences differed at 7 nucleotide sites from those of the closest species, Paramphistomum leydeni. Our data indicate that the ITS2 sequence could be a useful molecular marker for epidemiological studies on E. explanatum.
