| genotyping of giardia isolates in scotland: a descriptive epidemiological study. | giardiasis, caused by the intestinal protozoan parasite giardia intestinalis (synonyms: g. lamblia, g. duodenalis), is one of the most frequent parasites to infect the scottish population. transmission of the infective cysts in faecal matter is commonly via food and/or water. giardia is subdivided into assemblages, where clinical and epidemiological differences have been described between assemblages a and b. this snapshot descriptive epidemiological study examines 30 positive cases of giardia o ... | 2014 | 24125434 |
| an audit of cryptosporidium and giardia detection in scottish national health service diagnostic microbiology laboratories. | giardia duodenalis and cryptosporidium species are protozoan parasites capable of causing gastrointestinal disease in humans and animals through the ingestion of infective faeces. whereas cryptosporidium species can be acquired locally or through foreign travel, there is the mis-conception that giardiasis is considered to be largely travel-associated, which results in differences in laboratory testing algorithms. in order to determine the level of variation in testing criteria and detection meth ... | 2017 | 28274291 |
| prevalence of intestinal parasitic infestation, salmonellosis, brucellosis, tuberculosis, and hepatitis b among immigrant children in glasgow. | two hundred asian and 100 each of african, chinese, and scottish children were screened for intestinal parasitic infestations, salmonellosis, brucellosis, hepatitis b antigen (hbsag), and tuberculosis. there was a fairly high incidence of giardia lamblia among asian and scottish children and of trichuris trichiura among the chinese. hookworm ova were seen only in africa children. there were no chronic carriers of salmonella or brucella, and no one was suffering from salmonellosis or brucellosis. ... | 1977 | 843867 |
| epidemiology of parasitic protozoan infections in soay sheep (ovis aries l.) on st kilda. | the feral soay sheep (ovis aries l.) population on hirta, st kilda, is host to a diverse component parasite community, but previous parasitological studies of the population have only focussed on the metazoan species. this paper reports the first epidemiological study of the protozoan species comprising cryptosporidium parvum, giardia duodenalis and 11 species of eimeria in soay sheep across 3 years of varying host population density. prevalence and intensity of almost all species of protozoa si ... | 2007 | 16978448 |
| intestinal protozoa in homosexual men in edinburgh. | our objective was to determine the prevalence of intestinal protozoa in homosexual men attending a sexually transmitted diseases (std) clinic, to compare it with the prevalence in a previous study from the same clinic, and to examine the relationship, if any, between the presence of protozoa and sexual practices. men who consecutively attended the clinic and who gave a history of having had recent sexual contact with another male were invited to provide a stool sample for protozoological examina ... | 1999 | 10639057 |
