AbstractA set of nine A-4 colour plates with 118 photomicrographs illustrating the appearance and diagnostic features of all the common intestinal helminths and protozoan parasites known to infect humans. Produced in a robust plasticized format, the plates can be used as either a guide for laboratory and field workers in endemic countries or a teaching aid for students and trainees. The aim is to help the microscopist ascertain the presence of parasites in faeces, whether they be minute protozoan cysts or large helminth eggs, and to identify them correctly. With this goal in mind, the bench aids include pertinent laboratory instructions as well as high-quality images. The photomicrographs illustrate diagnostic features of each of the parasites as they appear in different preparations and at different magnifications. Each photomicrograph is produced with a measuring bar and accompanied by a short explanatory legend, which draws attention to distinctive features that help confirm diagnosis. Helminth eggs are illustrated in the first 36 photomicrographs, which show the diagnostic stages of the most common helminths, including nematodes, cestodes, schistosomes, and other trematodes. The remaining photomicrographs offer advice on the more difficult task of detecting and identifying intestinal protozoan trophozoites and cysts. Relevant laboratory techniques are described on the reverse side of the plates. Additional laboratory aids include dichotomous keys for the identification of amoebic trophozoites, trophozoites of intestinal flagellates, and cysts of amoebae and flagellates

Prevalence and seasonal variation of human intestinal parasites in patients attending hospital with abdominal symptoms in northern Jordan Jaran, A.S. (2016-10)This study was carried out to determine the prevalence of intestinal parasites and their seasonal variation in northern Jordan. A total of 21 906 stool samples were collected over a period of 4 years [2009-2013] from 5 government hospitals in 3 cities. Samples were processed and examined microscopically and by concentration methods. Parasitic infection was found in 9611 samples [44%]. Giardia lamblia was the most prevalent parasite [41%] followed by Entamoeba histolytica [31%] and Ent. coli [13%]; the least prevalent parasites were Ascaris ...
Prevention and control of intestinal parasitic infections : report of a WHO Expert Committee [meeting held in Geneva from 3 to 7 March 1986] WHO Expert Committee on Prevention and Control of Intestinal Parasitic Infections; World Health Organization (1987)Outlines new approaches to the prevention and control of intestinal parasitic infections made possible by the recent discovery of safe and effective therapeutic drugs, the improvement and simplification of diagnostic procedures, and advances in the understanding of parasite population biology. Newly available information on the economic and social impact of these infections is used to illustrate the necessity, as well as the feasibility, of bringing these infections under control. In view of the striking variations in the biology of different ...
El Kettani, S.; Azzouzi, E.; Boukachabine, K.; El Yamani, M.; Maata, A.; Rajaoui, M. (2008)An evaluation was made of the risk of contamination by faecal parasites in the population from the use of wastewater in agriculture. The study was based in 3 rural clusters in the northern region of Settat city, Morocco: 2 rural clusters exposed to untreated wastewater in agriculture and 1 not exposed. The sample comprised 333 people aged 3-60+ years: 214 exposed and 119 non-exposed. Stool samples were collected and examined for intestinal parasites. The results showed that the prevalence of intestinal parasitosis [i.e. evidence of at least 1 ...
