Antimicrobial resistance and molecular characterization of isolated from bovine mastitis samples in Nghe An province, Vietnam.

Background And Aim: Vietnam's dairy sector is in its early phase of large-scale farming development. Therefore, mastitis in cows is always a concern to farm owners. This study aimed to determine the antimicrobial susceptibility, resistance, and virulence-related genes of isolated from bovine mastitis in Nghe An province of Vietnam.

Molecular and morphological characterization of Dollfustrema bagarii (Digenea: Bucephalidae) metacercariae from aquaculture channel catfish (Ictalurus punctatus) in northern Vietnam.

White grub metacercariae were found in the livers and kidneys of diseased specimens of an introduced channel catfish, Ictalurus punctatus (Rafinesque), in Vietnam. Based on morphological features and 28S rDNA sequence analysis, the isolated metacercariae were identified as Dollfustrema bagarii (Digenea: Bucephalidae) Moravec & Sey. Histopathological examination shows that encysted metacercariae can change the tissue structure of the infected organs and is often accompanied by haemorrhaging and the presence of eosinophilic granular cell infiltration.

Decreasing trend of -lactam resistance in isolates from broiler chickens due to the cessation of ceftiofur administration.

Ceftiofur, a third-generation cephalosporin antimicrobial, was used in Japanese hatcheries for many years before 2012. We continue to study in broilers and their antimicrobial resistance. The current study aimed to express how the cessation of ceftiofur affects the antimicrobial resistance of isolated from broiler chickens in Kagoshima Prefecture, Japan in 2017 and 2018.

The incidence of Campylobacter contamination levels through Chicken-Sashimi Processing steps in A Small-scale Poultry processing plant applying the External stripping method.

This study aimed to analyze the incidence of Campylobacter in a small-scale chicken meat processing plant producing "chicken-sashimi", and determine the effectiveness of surface burning as a treatment during processing. The most probable number (MPN) method was used to analyze the load of Campylobacter in 48 samples from four different processing steps (de-feathering, chilling, surface burning, and final-products; 12 samples each). We found the highest load of isolated bacteria in chicken skin after de-feathering.

Increased Salmonella Schwarzengrund prevalence and antimicrobial susceptibility of Salmonella enterica isolated from broiler chickens in Kagoshima Prefecture in Japan between 2013 and 2016.

This study aimed to analyze the Salmonella serovars, measure the minimum inhibitory concentration of antimicrobials, and examine the antimicrobial resistance genes of Salmonella isolated from 192 broiler flocks in Kagoshima Prefecture in Japan, from 2013 to 2016. We found that all Salmonella isolates belonged to three serovars: Salmonella Manhattan, S. Infantis, and S.

Prevalence of Salmonella in broiler chickens in Kagoshima, Japan in 2009 to 2012 and the relationship between serovars changing and antimicrobial resistance.

Background: This study aimed to examine the prevalence, serovars, and antimicrobial resistance of Salmonella isolates from broiler chickens in Kagoshima, Japan. A total of 192 flocks and 3071 samples were collected from broiler chickens at local farms in Kagoshima, Japan from 2009 to 2012.

Result: Among the tested farms, 49.

Prevention of LLC-PK(1) cell overgrowth in a bioartificial renal tubule device using a MEK inhibitor, U0126.

A common approach to construct a bioartificial renal tubule system is to utilize renal tubular cells seeded in porous polymer membrane hollow fibers. We have reported that overgrowth of renal tubular cells was not beneficial for the transport and reabsorption functions of bioartificial tubules. Therefore, long-term maintenance of a confluent monolayer of cells in hollow fibers is essential and technically challenging.
