The object of this study was to determine the importance of domestic cats in the epidemiology of human giardiasis. Of six laboratory-reared cats inoculated with cultured Giardia lamblia trophozoites from humans, only one showed the presence of cysts in the feces, and cysts were found on only 1 of the 80 days of observation. In a second experiment, eight cats were inoculated with G. lamblia cyst...

We describe the synthesis of a novel hydrophilic derivative of a tetradentate β-diketone europium ligand that was used to prepare an immunoconjugate probe against Giardia lamblia cysts. We used a Gated Autosynchronous Luminescence Detector (GALD) to obtain high quality delayed luminescence images of cells 30-fold faster than ever previously reported.

Giardia lamblia is a frequent pathogen in persistent diarrhoea. Both humoral and cellular immune responses are important in clearing the parasite and providing immunity. A rapid sensitive and specific serological test like dot ELISA could be useful for early detection of Giardia specific serum antibodies for routine diagnosis. This study reports the use of dot ELISA for the detection of Giardia...

Background: Infected with intestinal parasites is one of the most important health and economical problems, which could have different effects, such as diarrheal diseases or death associated. The purpose of this study was to determine the level of prevalence of Cryptosporidium and Giardia parasites in the vegetable marketed in Ilam city. Methods: This study was performed on 280 samples of fresh...

BACKGROUND The primary aims of this study were to determine the incidence of Giardia infections in dairy herds on farms in the New York City Watershed region and to evaluate risk factors associated with infections. Because co-infections of Giardia and Cryptosporidium spp. are common in this population, we also evaluated the effect of herd infection status on Giardia infections. METHODS Farms ...

Some genes in the candidate early-branching eukaryote Giardia lamblia occur in separate pieces, transcribed from non-contiguous chromosomal locations. The pre-mRNAs from the separate pieces apparently find each other by regions of complementarity and are subsequently spliced together by the spliceosome. Could genes in pieces, transcribed into separate pre-mRNAs, have been an early feature of sp...

Design and synthesis of a novel nucleotide anti-Giardia agent that is micromolar inhibitor of Giardia trophozoite growth in culture is described.

The Tasmanian devil (Sarcophilus harrisii) is a carnivorous marsupial found only in the wild in Tasmania, Australia. Tasmanian devils are classified as endangered and are currently threatened by devil facial tumour disease, a lethal transmissible cancer that has decimated the wild population in Tasmania. To prevent extinction of Tasmanian devils, conservation management was implemented in 2003 ...
