Abstract
Background and objectives: Helicobacters are gastric and enterohepatic and live in the gut. The role of enterohepatic Helicobacters as intestinal pathogens is uncertain, while stomach Helicobacters are well-known. The prevalence of Helicobacter species in cat feces helps us understand their impact on cat health and human disease transmission. This study used PCR to identify Helicobacter spp. in feces samples from healthy and diarrhoeic cats, independent of the reason. The study also compared intestinal and stomach Helicobacter species.
Materials and methods: PCR analysis was performed on fecal samples from 40 cats, with 20 cats having diarrhea and 20 cats showing no symptoms. The PCR analysis aimed to detect Helicobacter's presence using a method that identifies the bacteria through the 16S rRNA gene.
Results: The diarrhoeic group had a greater prevalence of infection (17:9 ratio), with an overall 65% infection rate detected. Cats that were older than 2 years showed a higher incidence of disease. H. canis had the highest occurrence rate (69.2%), followed by H. bilis, H. bizzozeronii, and H. salomonis. Significantly, H. pylori, H. felis, and H. heilmannii were not reported.
Conclusion: H. canis was the predominant species found in both healthy and diarrheic cats, indicating the need for more investigation. The detection of the gastric species H. salomonis and H. bizzozeronii further complicates the classification. This highlights the complex nature of Helicobacter infections in cats, emphasizing the need for further investigation to guide the development of preventative measures and treatment techniques for both veterinary and public health purposes.
期刊介绍：
The Iranian Journal of Microbiology (IJM) is an international, multi-disciplinary, peer-reviewed journal that provides rapid publication of the most advanced scientific research in the areas of basic and applied research on bacteria and other micro-organisms, including bacteria, viruses, yeasts, fungi, microalgae, and protozoa concerning the development of tools for diagnosis and disease control, epidemiology, antimicrobial agents, clinical microbiology, immunology, Genetics, Genomics and Molecular Biology. Contributions may be in the form of original research papers, review articles, short communications, case reports, technical reports, and letters to the Editor. Research findings must be novel and the original data must be available for review by the Editors, if necessary. Studies that are preliminary, of weak originality or merely descriptive as well as negative results are not appropriate for the journal. Papers considered for publication must be unpublished work (except in an abstract form) that is not under consideration for publication anywhere else, and all co-authors should have agreed to the submission. Manuscripts should be written in English.
