Metabarcoding study of potential pathogens and zoonotic risks associated with dog feces in Seoul, South Korea. PLoS Negl Trop Dis 2024; 18:e0012441.

Abstract
BACKGROUND A significant portion of South Korea's population, approximately a quarter, owns pets, with dogs being the most popular choice among them. However, studies analyzing the fecal organism communities of dogs in South Korea are lacking, and limited efforts have been exerted to identify pathogens with potential zoonotic implications. Therefore, this study aimed to investigate potential pathogens using metabarcoding analysis and evaluate the risk of zoonotic diseases in dog feces in Seoul, South Korea. METHODOLOGY Fecal samples were collected from both pet and stray dogs in the Mapo district of Seoul. Next-generation sequencing (NGS) was utilized, employing 16S rRNA amplicon sequencing to identify prokaryotic pathogens, and 18S rRNA amplicon sequencing for eukaryotic pathogens. The data obtained from the QIIME2 pipeline were subjected to various statistical analyses to identify different putative pathogens and their compositions. PRINCIPAL FINDINGS Significant variations in microbiota composition were found between stray and pet dogs, and putative prokaryotic and eukaryotic pathogens were identified. The most prevalent putative bacterial pathogens were Fusobacterium, Helicobacter, and Campylobacter. The most prevalent putative eukaryotic pathogens were Giardia, Pentatrichomonas, and Cystoisospora. Interestingly, Campylobacter, Giardia, and Pentatrichomonas were found to be significantly more prevalent in stray dogs than in pet dogs. The variation in the prevalence of potential pathogens in dog feces could be attributed to environmental factors, including dietary variances and interactions with wildlife, particularly in stray dogs. These factors likely contributed to the observed differences in pathogen occurrence between stray and pet dogs. CONCLUSIONS/SIGNIFICANCE This study offers valuable insights into the zoonotic risks associated with dog populations residing in diverse environments. By identifying and characterizing putative pathogens in dog feces, this research provides essential information on the impact of habitat on dog-associated pathogens, highlighting the importance of public health planning and zoonotic risk management.

Abstract
The aim of our study was to determine the association of Helicobacter spp. that had flexispira morphology with ovine abortion, and to understand the importance of these organisms as a cause of ovine abortion in New Zealand. A retrospective diagnostic survey was carried out on laboratory submissions from ovine abortion outbreaks. A comparison was made of the proportion of laboratory submissions where Helicobacter spp. were detected from flocks that had no other agent identified (group A) with a group that had a known cause of abortion identified (group B). This latter group was considered to be a negative control, given the premise that Helicobacter spp. were not causing abortions and that Helicobacter spp. should be present at a lower rate in the group. Where no diagnosis had been made, aborted material was positive for Helicobacter spp. with flexispira morphology in 8 submissions (20%, 8/40) from 5 of the 31 survey farms (16%, 5/31). Helicobacter spp. were not detected in any of the 18 submissions from the 17 control farms (group B). Helicobacter spp. were confirmed by 16S ribosomal RNA sequencing of 3 of the Helicobacter spp. isolated by culture from the livers of aborted sheep fetuses, and 7 of the 8 where samples were positive in a Helicobacter PCR assay. The Helicobacter spp. were identified as Helicobacter trogontum (Flexispira taxon 5 genotype) and Helicobacter bilis (Flexispira taxon 8 genotype). The findings support Helicobacter spp. being a probable causative agent of ovine abortions in New Zealand.
