Microscopy of stool samples is a labour-intensive and inaccurate technique for detection of intestinal parasites causing diarrhoea and replacement by PCR is attractive. Almost all cases of diarrhoea induced by parasites over a nine-year period in our laboratory were due to , species, or detected by microscopy. We evaluated and selected in-house singleplex real-time PCR (RT-PCR) assays for these pathogens in 99 stool samples from patients suspected of having intestinal parasitosis tested by microscopy. The strategy included a genus-specific PCR assay for and , with subsequent identification by a PCR that distinguishes between the two species. was detected in five and in one out of 68 microscopy-negative samples. The performance of the in-house RT-PCR assays was compared to three commercially available multiplex test (MT-PCR) kit systems in 81 stool samples, collected in 28 microscopy-positive and 27 microscopy-negative samples from individuals suspected of intestinal parasitosis and in 26 samples from individuals without suspicion of parasitic infection. The in-house assays detected parasites in more samples from patients suspected of having parasitosis than did any of the kits. We conclude that commercial kits are targeting relevant parasites, but their performance may vary.

Haplorchis taichui is the minute intestinal fluke (MIF), presents a significant public health concern in Thailand. Despite praziquantel (PZQ) being the main treatment, concerns over recurrent use and drug resistance have surfaced. Thus, local herbal alternatives effective against gastrointestinal parasites could be crucial for reducing issues, necessitating exploration of herbal sources for alternative treatments.

Migratory birds are potential vectors transmitting zoonotic parasites, bacteria, and viruses that can significantly affect human health. Over 60 diseases have been identified to be associated with these birds. Given their close proximity to human habitation, the potential transmission of zoonotic diseases is a major concern for the public.

The aim of this study was to investigate whether Trypanosoma vivax is transmitted via rectal palpation in cattle, using the same glove with different blood scores, from an animal with an acute infection of this protozoan. In addition, the efficacy of iodine as disinfectant, together with water with or without the presence of feces, to prevent the transmission of T. vivax in cattle during the rectal palpation process was evaluated in the laboratory and animals.

The nutria (Myocastor coypus) is a semiaquatic rodent that originally inhabited South America. However, the animals have spread to different continents as alien species, and their numbers are quickly increasing, especially in North America, Europe, and Eastern Asia including Japan. Although nutrias have been suggested to serve as reservoirs for pathogens, including parasites, there have been few reports on this subject.
