摘要

背景和目的:螺旋杆菌有胃型和肠肝型两种,生活在肠道中。肠肝螺旋杆菌作为肠道病原体的作用尚不确定,而胃螺旋杆菌则是众所周知的。猫粪便中螺旋杆菌的流行有助于我们了解它们对猫咪健康和人类疾病传播的影响。这项研究利用 PCR 技术鉴定了健康猫和腹泻猫粪便样本中的螺旋杆菌属,与原因无关。研究还比较了肠道和胃中的螺旋杆菌种类:对 40 只猫的粪便样本进行了 PCR 分析,其中 20 只猫腹泻,20 只猫无症状。PCR 分析的目的是通过 16S rRNA 基因识别细菌的方法检测是否存在螺旋杆菌:腹泻组的感染率更高(比例为 17:9),总体感染率为 65%。两岁以上的猫发病率更高。犬细小病毒感染率最高(69.2%),其次是比里氏小病毒、比佐龙小病毒和沙门氏菌。值得注意的是,幽门螺杆菌、费里螺杆菌和海尔曼尼螺杆菌均未见报道:结论:在健康猫和腹泻猫身上发现的主要病原体都是犬细小病毒,这表明有必要进行更多的调查。沙洛单氏菌(H. salomonis)和比佐戎氏菌(H. bizzozeronii)的发现使分类更加复杂。这凸显了猫螺旋杆菌感染的复杂性,强调了进一步调查的必要性,以指导兽医和公共卫生预防措施和治疗技术的发展。

Prevalence and diversity of enteric Helicobacter spp. in healthy and diarrheic cats.

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.
