Multi-laboratory evaluation of the Illumina iSeq platform for whole genome sequencing of , and .

There is a growing need for public health and veterinary laboratories to perform whole genome sequencing (WGS) for monitoring antimicrobial resistance (AMR) and protecting the safety of people and animals. With the availability of smaller and more affordable sequencing platforms coupled with well-defined bioinformatic protocols, the technological capability to incorporate this technique for real-time surveillance and genomic epidemiology has greatly expanded. There is a need, however, to ensure that data are of high quality.

Detection of the parasitic nematode, Pseudocapillaria tomentosa, in zebrafish tissues and environmental DNA in research aquaria.

Although zebrafish continue to increase in popularity as a vertebrate animal model for biomedical research, chronic infectious diseases in laboratory populations remain prevalent. The presence of pathogens such as Pseudocapillaria tomentosa, a parasitic nematode found in the intestine of infected zebrafish, can significantly influence experimental endpoints and negatively impact reproducibility of research findings. Thus, there is a need for screening tests for zebrafish with the sensitivity to detect even low levels of pathogens present in tissues.

Response of intestinal microbiota to antibiotic growth promoters in chickens.

Antibiotic growth promoters (AGPs) have been used as feed additives to improve average daily weight gain and feed efficiency in food animals for more than five decades. However, use of AGPs is associated with the emergence of antibiotic-resistant human pathogens of animal origin, posing a significant threat to food safety and public health. Thus, development of novel alternatives to AGPs is important to mitigate antimicrobial resistance in foodborne pathogens.
