| resistance of mice to infection with the human strain of hymenolepis nana. | six attempts were made to infect mice by feeding them eggs of the human strain of hymenolepis nana, but none was successful. no eggs were found in the mouse faeces 14 days after feeding, and no adult worms were recovered at post mortem examination. in attempts to induce cysticercoids to infect mice, beetles were either fed on infected human faeces or given hymenolepis eggs on filter paper. both methods were unsuccessful, as no cysticercoids were recovered six days after exposure of the beetles. | 1989 | 2604465 |
| [investigation on zoonoses among veterinary technicians]. | we conducted a survey on how much veterinary clinics staff, mostly veterinary technicians, know about zoonosis and how extensively they inform pet owners of ways to prevent zoonosis. the number of people who took part in the survey was 1,057. the ratio of people who said their knowledge on zoonosis is "neither sufficient nor insufficient" was 53.8%, which is larger than the ratio of people who replied "sufficient" or "insufficient." the percentage of those who said their way of giving informatio ... | 2003 | 12806928 |

| intestinal parasitoses among wayampi indians from french guiana. | intestinal parasitism and its epidemiological characteristics were studied in an isolated amerindian population from upper oyapock (french guiana) that has retained its traditional social and cultural specificities. this population consisted of 138 wayampi indians, 68 adults and 70 children (below the age of 15 years), with a sex ratio (m/f) of 0.86, spread over the four villages of the community of trois sauts, corresponding to more than two thirds of the population recorded as inhabiting the s ... | 2002 | 12116863 |
| a molecular phylogeny of nuclear and mitochondrial sequences in hymenolepis nana (cestoda) supports the existence of a cryptic species. | since isolates of hymenolepis nana infecting humans and rodents are morphologically indistinguishable, the only way they can be reliably identified is by comparing the parasite in each host using molecular tools. in the current study, isolates of h. nana from rodent and human hosts from a broad geographical range were sequenced at the ribosomal first internal transcribed spacer (its1), the mitochondrial cytochrome c oxidase subunit 1 (c01) gene and the nuclear paramyosin gene loci. twenty-three ... | 2002 | 12553576 |
