Giardia infection is a common clinical problem in humans and pets. The diagnosis of giardiasis is challenging as hosts intermittently excrete protozoan cysts in their feces. In the present study, we comparatively evaluated two methods of serial fecal sampling in humans, dogs, and cats from Rio de Janeiro, Brazil. The Faust et al. technique was used to examine fecal specimens collected in tripli...

Cryptosporidium and Giardia are pathogenic agents which cause risk to public health. The goal of this research was evaluate the infection by cryptosporidiosis giardiasis in a population Cerrado biome its relation land use. Raw water samples were collected from 41 different surface sources state Goiás (Brazil). parasites quantified via membrane filtration method. probability an individual contra...

OBJECTIVES Giardia (G.) lamblia is a parasite that causes giardiasis in humans and other mammals. The common treatment produces unpleasant side effects. The ethnopharmacology for management of parasitic infections accelerates and guides the search for new chemical objects. This study assessed the in vitro cytotoxicity of Sambucus (S.) ebulus fruit against Cysts of G. lamblia. MATERIALS AND ME...

Objective. The purposes of this study were to determine whether secnidazole administered at a single dose of 10 mg/kg, orally, lessens or eliminates Giardia cyst shedding, and to validate the benefit of secnidazole treatment on clinical signs and faecal consistency in lambs naturally infected with Giardia duodenalis. Materials and methods. To this extent weaned 12 weeks of age lambs were select...

Since the Giardia lamblia cyst wall is necessary for survival in the environment and host infection, we tested the hypothesis that it contains proteins other than the three known cyst wall proteins. Serial analysis of gene expression during growth and encystation revealed a gene, "HCNCp" (High Cysteine Non-variant Cyst protein), that was upregulated late in encystation, and that resembled the c...

Protozoan enteroparasites of the genera Cryptosporidium and Giardia have emerged over the past decades as major waterborne pathogens. Both parasites are among the major causative agents of gastroenteritis and nutritional disorders in humans, with tens of millions of new cases occurring every year. Although cryptosporidiosis and giardiasis are normally self-limiting in immune-competent individua...

Background: Giardia lamblia was the most common parasite-caused gastrointestinal ailment in United States by late 1980s, and it is now a significant global public health issue. Giardiasis an infectious condition that may have both short-term long-term effects. Objective: To assess frequency of giardia infection children presented with acute diarrhea to tertiary care hospital. Methodology: The c...

Cryptosporidium and Giardia are of public health importance, with recognized transmission through recreational waters. Therefore, both can contaminate marine waters and shellfish, with potential to infect marine mammals in nearshore ecosystems. A 2-year study was conducted to evaluate the presence of Cryptosporidium and Giardia in mussels located at two distinct coastal areas in California, nam...
