Article Abstract
Epidemiological and pathological studies on Helicobacter spp. in feline stomachs in Japan were conducted using genus- and species-specific (H. felis, H. bizzozeronii, H. heilmannii sensu stricto [s.s.] and H. pylori) polymerase chain reactions (PCRs), ureAB gene sequencing and histopathology. PCR results showed that 28 of 56 cats were infected with Helicobacter spp., and H. heilmannii s.s. was the most prevalent species by both PCR (28/28) and ureAB gene sequencing (26/28). Some of the sequences showed high similarities with those from human patients with gastric diseases (99%). There were no significant differences between Helicobacter spp.-positive and -negative cats in the severity of chronic gastritis (P=0.69). This is the first extensive epidemiological study on feline gastric Helicobacter spp. in Japan.
Disinfectant application to gloved hands before handling SPF mice is standard practice to minimize transmission of pathogens and microbial contamination between cages. The risk of contamination with murine pathogens on gloves as well as the efficacy of disinfectant application for this step is largely unknown. This study aimed to determine if murine norovirus (MNV), Helicobacter spp.

The study investigates the presence of Helicobacter species, specifically H. pylori and "Candidatus H. bovis," in the abomasum of dairy cattle and sheep in Northern Italy, focusing on their potential role in gastric diseases.
Out of 25 dairy cows and 24 sheep examined, 96% of the bovine samples and 42% of the ovine samples tested positive for Helicobacteraceae, with "Candidatus H. bovis" found predominantly in the bovine pyloric mucosa.
The findings suggest that "Candidatus H. bovis" is common in cattle but not linked to inflammation, indicating a specific adaptation to bovine hosts, and the potential for cattle and sheep
Helicobacter pylori, a pathogenic bacterium responsible for multiple gastrointestinal disorders, has emerged as a major global concern due to rise in antibiotic resistance. Unwanted side effects of antibiotics therapy are further complicating the treatment strategies. Consequently, an alternative approach, using probiotics has emerged as a promising solution for treating H.
* A total of 531 saliva samples were analyzed from two Tribal Nation festivals and compared with 453 samples previously collected in the Midwest, employing logistic and linear regression models.
* Results indicated varying seroprevalences of specific infections, with higher antibody responses to certain noroviruses and unique associations between lifestyle factors (like water consumption and animal contact) and infection rates in the Tribal populations.
EnteroBase is a web-based platform that offers curated databases of genome sequences from over 1.1 million bacterial isolates, including notable pathogens like Streptococcus and Mycobacterium tuberculosis.
The platform now features tools for detecting antimicrobial resistance and a new bubble plot tool for visualizing bacterial genomic structures.
Enhanced access and functionalities are provided through a user-friendly interface and a RESTful API, with ongoing development by an international consortium to improve and maintain the system.
