molecular characterization of trichomonads isolated from animal hosts in the philippines.trichomonads are amitochondrial anaerobic flagellated protists that are either parasites or commensals, generally living in the digestive or genitourinary tract of humans and animals. it has been reported that these protozoa can migrate to other sites in their target host, can adapt to new hosts, and are capable of zoonotic transmission. in this study, 59 trichomonad isolates from different animal hosts in the philippines were identified and characterized. primer sets were designed and were succ ...201323622817
first evidence of previously undescribed trichomonad species in the intestine of pigs?three different parasites of the phylum parabasala (tritrichomonas foetus, trichomitus rotunda and tetratrichomonas buttreyi) have been described in pigs. in a previous study (mostegl et al., 2011) approximately 47% of 91 paraffin wax-embedded intestinal samples of pigs which were trichomonas-positive by in situ hybridization using a probe with a broad reactivity spectrum contained other species than t. foetus. out of these, intestinal trichomonads from three pigs (pigs 1-3) were further analyze ...201122093906
investigations on the prevalence and potential pathogenicity of intestinal trichomonads in pigs using in situ pigs, three different trichomonad species (tritrichomonas foetus, tetratrichomonas buttreyi and tritrichomonas rotunda) have been described as commensals in the large intestine. the aim of this study was to gain further knowledge on the prevalence and pathogenicity of trichomonads in pigs by using a morphology-based approach. chromogenic in situ hybridization (ish) is a technique which allows direct localization of the protozoa in the intestinal tissue and correlation of the infection with pa ...201021236578
ultrastructural study of a tetratrichomonad isolated from pig fecal samples.trichomonads found in pigs include the commensal tritrichomonas suis (more well known because of its synonymy to tritrichomonas foetus, a trichomonad parasite of cattle and other animals) and tetratrichomonas buttreyi, which appear similar to tritrichomonas suis under the light microscope. a trichomonad isolated from pig fecal samples was subjected to scanning and transmission electron microscopy for ultrastructural study. the organism's ultrastructure revealed features commonly found in trichom ...200818682985
ultrastructural study of a tetratrichomonad species isolated from prepucial smegma of virgin bulls.we present observations on an unusual tetratrichomonad species isolated from preputial smegma of virgin bulls. ultrastructural studies were performed using scanning and electron microscopy techniques. this protozoan presents four anterior flagella of unequal length and a recurrent one forming the undulating membrane. it shows one anterior nucleus, a golgi complex, an axostyle, and a costa. the hydrogenosomes are rather elongated, seen in groups, and presenting different electron densities. vacuo ...200314630428
the prevalence of intestinal trichomonads in chinese pigs.intestinal infection of pigs with trichomonads, (tritrichomonas suis, tetratrichomonas buttreyi, and pentatrichomonas hominis) has been reported in many countries, such as the philippines, belgium, and the czech republic. however, the prevalence of trichomonads infection of swine in china has not yet been investigated. in this study, we used small subunit ribosomal rna genes to detect the prevalence of t. suis, t. buttreyi and p. hominis among 158 fecal specimens from healthy pigs. infection rat ...201525981103
isolation of the trichomonad tetratrichomonas buttreyi (hibler et al., 1960) honigberg, 1963 in bovine diarrhoeic faeces.a trichomonad was found in the faeces of a heifer with watery diarrhoea. it was classified as tetratrichomonas buttreyi according to its morphology as revealed by scanning electron microscopy. this flagellate was successfully maintained in a cysteine-peptone-liver medium. it is, to our knowledge, the first report of tetratrichomonas buttreyi in spain. this trichomonad appears to be a nonpathogenic commensal which often proliferates in fluid faeces.19979195708
