Abstract
Urban rats are significant reservoirs of zoonotic endoparasites, posing serious health risks to humans. This study aimed to detect common endoparasites in wild brown rats (Rattus norvegicus) in Budapest, addressing the current lack of endoparasite surveys in Hungary. Carcasses of 131 rats collected following extermination were examined. Three zoonotic helminths were identified: Hymenolepis nana and Hymenolepis diminuta in the jejunum, and Calodium hepaticum in the liver. Additionally, non-zoonotic parasites were detected, including Eimeria spp., Entamoeba muris, Heterakis spumosa, Nippostrongylus brasiliensis, Eucoleus gastricus, Aonchotheca annulosa, Syphacia muris (intestine), and Trichosomoides crassicauda (urinary bladder). Helminth infection prevalence was 83.9 %, with no noticeable differences in prevalence or infection intensity between sexes. These findings highlight the potential public health risk posed by zoonotic parasites in urban rat populations, emphasising the importance of surveillance to mitigate possible human infection. This study demonstrates a practical and economical approach to monitoring urban rat populations. Further large-scale studies are recommended to better understand the parasitic landscape in Hungary's rat populations, leveraging data from rat control programs.
期刊介绍：
Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
