The recent near-epidemic incidence of Giardia lamblia infection in visitors to the Soviet Union illustrates the importance of this intestinal flagellate as a cause of diarrhea in travelers worldwide. Clinical states range from the asymptomatic cyst-passing stage, to the chronic or subacute stage mimicking gallbladder or ulcer disease, to the transient or, rarer, persistent acute stage with stea...

BACKGROUND Giardia lamblia is one of the most common protozoal infections in human especially children. Metronidazol (MTZ) is the drug of choice for treatment of giardiasis; its chemical composition possesses major threats and is becoming less sensitive. This study aimed to search for natural extracts alternative to MTZ. METHODS In-vivo effects of dichloromethane extracts of ginger and cinnam...

Three drinking water treatment plants (DWTPs) differing in source water and treatment capacity were investigated for the potential passage of waterborne protozoan (oo)cysts through conventional processing. DWTP I (15,000 L/s), DWTP II (7,500 L/s) and DWTP III (4,300 L/s) provide drinking water for approximately 2.7 million inhabitants of the Metropolitan District of Caracas (Venezuela). The US ...

Giardia lamblia, the protist that causes diarrhea, makes an Asn-linked-glycan (N-glycan) precursor that contains just two sugars (GlcNAc(2)) attached by a pyrophosphate linkage to a polyprenol lipid. Because the candidate cis-prenyltransferase of Giardia appears to be more similar to bacterial enzymes than to those of most eukaryotes and because Giardia is missing a candidate dolichol kinase (o...
