Article Synopsis

Dissemination of ESC-resistant Salmonella in egg production poses a public health risk, as these bacteria can acquire resistance genes through insertion sequences.
A study analyzed 224 Salmonella isolates across various breeding and processing facilities in Japan, uncovering that 17.9% were resistant to multiple antibiotics, but not to azithromycin and meropenem.
Genetic analysis revealed that certain resistant strains harbored IncA/C plasmids with resistance genes, facilitating the transfer of these genes within the breeding chain.

We screened for the presence of Borrelia spp. in ticks collected from vegetation by flagging and from wild animals between May 2017 and November 2018 in Fukuoka, located in the northern Kyushu region of Japan. A total of 1,601 ticks were collected and separated based on morphology into nine species, namely Ixodes turdus, I.
