| dc.description.abstract | This document is a university course on the diagnosis of parasites, intended for 3rd-year Bachelorstudents in Parasitology, written by Dr. Tolba Mounia. It covers the morphological, anatomical, and classificatorycharacteristics of major parasitic groups, withemphasis on diagnostic features and life cycles. Introduction The course highlights the global burden of parasitic infections (e.g., Trypanosomiasis, Leishmaniasis, Malaria, Schistosomiasis, Filariasis, Echinococcosis). It notes thatincreasedtravel, immigration, blood transfusions, and organ transplants have spread thesediseases to non-endemic areas. Diagnosisremainschallenging, relyingheavily on microscopy, thoughmolecularmethods (real-time PCR, LAMP) and serologicalassays are advancing. ChapterI:Protozoa (KingdomProtista) • General characteristics:Unicellular, eukaryotic; locomotion by pseudopods, flagella, or cilia; reproduction asexual (binary fission, budding, schizogony) and sexual (gametogenesis, conjugation). • Classification: o Rhizopoda (Amoebae): Move by pseudopods; examples Entamoeba histolytica (amoebicdysentery), E. coli (non-pathogenic). o Zooflagellates:IncludesTrypanosomatidae (Leishmania, Trypanosoma), Trichomonadids (Trichomonas vaginalis), Diplomonadids (Giardia intestinalis). o Ciliophora (Ciliates): Covered withcilia; Balantidium coli (pathogenic to humans and pigs). o Apicomplexa (Sporozoa):Intracellular parasites; apical complex for host cellpenetration. IncludesGregarines, Coccidia (Eimeria, Toxoplasma gondii, Cryptosporidium), and Hemosporidia (Plasmodium speciescausing malaria). ChapterII:Platyhelminthes (Flatworms) • Class Turbellaria:Mostly free-living, ciliatedepidermis, acoelomate; example Planaria. • Class Cestodes (Tapeworms): o Taeniasolium, Taeniasaginata: scolex with suckers/hooks, strobile of proglottids, hermaphroditic. o Classification of carnivore cestodes:Taeniidae (Taenia, Echinococcus), Dilepididae (Dipylidiumcaninum), Mesocestoididae. o Life cycle, diagnosis (eggmorphology, proglottid identification), treatment (praziquantel, niclosamide), prophylaxis. • Class Trematodes (Flukes): o Example Fasciolahepatica:leaf-shaped, two suckers, hermaphroditic, complex life cycle involvingintermediate host (snail Limnea). o Digestive, excretory (protonephridia), nervous, and reproductive systemsdescribed. o Monogeneans (single host) vs. Digeneans (multiple hosts). • ClassNematodes / Roundworms) : • General anatomy:Cylindrical body, cuticle, pseudocoelom, complete digestive tract, separate sexes (sexualdimorphism). • Integument:Cuticlewith moults; epidermalcords. • Musculature: Longitudinal myoepithelialcells. • Digestive system:Mouthwithlips or hooks, esophagus, intestine, rectum, anus. • Excretorysystem:Glandular (renettes) or tubular (lateralcanals). • Nervoussystem:Peri-oesophageal ring with nerve cords. • Reproductive system: Male (testis, seminalvesicle, cloaca, copulatory spicules) and female (ovaries, oviducts, uteri, vagina). • Development: Five larval stages with four moults. Diagnostic Techniques Mentioned • Microscopy (stoolexamination, bloodsmears, Graham scotch test, biopsy). • Molecularmethods (PCR, LAMP). • Serologicalassays (ELISA, immunofluorescence, etc.). • Coproscopy (egg and cyst identification) | |
