Study Notes
Leishmania and Giardia: Parasitic Infections Summary
- Leishmania donovani is found in southern Bulgaria and causes visceral leishmaniasis, transmitted by infected sandflies
- Visceral leishmaniasis symptoms include high fever, spleen and liver enlargement, darkened skin, and weight loss
- Diagnosis is through demonstration of amastigotes in tissue smears, serodiagnosis, and molecular diagnosis (PCR)
- Prophylaxis includes insecticide spraying, destruction of animal reservoirs, and use of anti-bite repellents
- Leishmania tropica complex includes three species causing old world cutaneous leishmaniasis
- Cutaneous leishmaniasis has two subtypes: urban (dry) and rural (wet), with different clinical presentations
- Mucocutaneous leishmaniasis caused by L. braziliensis complex is severe and can lead to disfigurement
- Diagnosis of mucocutaneous leishmaniasis is through demonstration of amastigotes in smears and serology
- Prophylaxis includes use of insect repellents, insecticide spraying, and protective measures for forest workers
- Giardia lamblia is found worldwide and lives in the duodenum in two morphological forms: cyst and trophozoite
- Transmission occurs through ingestion of cysts in contaminated water and food, with children commonly affected
- Giardia damages the intestine mechanically and through release of toxins, facilitated by antigenic variation and variant-specific surface proteins

African Trypanosomiasis and Leishmaniasis Overview
- Trypanosoma brucei is a parasite that invades connective tissue, lymph nodes, blood, and the central nervous system
- Tsetse flies, including Glossina morsitans and Glossina palpalis, are vectors for Trypanosoma brucei rhodesiense and Trypanosoma brucei gambiense
- Trypanosoma brucei has various forms including trypomastigote, procyclic, epimastigote, and metacyclic forms
- Trypanosoma brucei evades the immune system through antigenic variation, which leads to exhaustion of the immune system and an increase in blood levels of antibodies
- Trypanosoma brucei rhodesiense causes acute sleeping sickness, while Trypanosoma brucei gambiense causes chronic sleeping sickness
- Clinical features of sleeping sickness include a painless chancre, fever, rashes, lymph node enlargement, and CNS involvement leading to coma and death
- Trypanosomiasis can be diagnosed through detection of trypanosomes in lymph node aspirate, blood smear, and stained smear of cerebrospinal fluid
- Prophylaxis of African trypanosomiasis involves the control of tsetse fly population through insecticide spraying, traps, and baits
- Dourine is a parasitic venereal disease of equines caused by Trypanosoma equiperdum, which is transmitted by sexual contact
- Leishmania is a genus of obligate intracellular parasites that pass their life cycle in two hosts: the mammalian host and the insect vector, female sandfly
- Leishmania donovani causes visceral leishmaniasis and multiplies within macrophages in humans and other mammalian hosts
- Three different diseases are caused by various species of genus Leishmania: visceral leishmaniasis, cutaneous leishmaniasis, and mucocutaneous leishmaniasis
