The aim of the present study was to evaluate and compare efficiacy albendazole paromomycine treatments against natural Giardia spp. infection in calves. calves were divided two groups six animals each with similar parasitic loads Giardiaspp. cysts. Albendazole (20 mg/kg) paromomycin (50 administrated orally group A P, respectively, for three consecutive days. efficiacies drugs evaluated by anal...

Little is known of the prevalence of Cryptosporidium and Giardia in domestic cats in Western Australia and their potential role as zoonotic reservoirs for human infection. In the present study, a total of 345 faecal samples from four different sources were screened for the presence of Cryptosporidium and Giardia by PCR and genotyped by sequence analysis. Oocyst numbers and cyst numbers for Cryp...

Giardia lamblia is the most frequently identified intestinal protozoan parasite in the U.S.A. and U.K., and is one of the more common causes of diarrhoea in children in the developing world. Chronic infections can result in enteropathy and malabsorption, contributing to growth retardation in children (Farthing et al., 1986). Giardia is commonly found in patients with acquired immunodeficiency s...

BACKGROUND Giardia lamblia is a common intestinal parasite that has been reported all over the world. OBJECTIVES This study was conducted to evaluate the effect of ozonized organic extra-virgin olive oil on the cyst of G. lamblia. METHODS The olive oil was ozonized based on international standards and confirmed by the world health organization (WHO) at various times in a generator. The ozon...

Giardia intestinalis is a parasite protist considered a living fossil because it is placed in the earliest divergence and deepest branch in eukaryote evolution. This parasite grows in vitro as trophozoites and under some conditions differentiates into cysts, characterized by presence of a cyst wall (CW). Proteins and carbohydrates compose the CW of the parasite and are transported by the Encyst...

The purpose of the present study was to evaluate the effect of chloroquine treatment on cyst excretion in calves naturally infected with Giardia duodenalis. The calves were randomly assigned into two groups based on placebo (group I, n=7 untreated control calves) or treatment (group II, n=7 calves treated orally with 2.5 mg/kg chloroquine twice daily for five consecutive days). The G. duodenali...

BACKGROUND Giardia passes through two stages during its life cycle, the trophozoite and the cyst. Cyst formation involves the synthesis of cyst wall proteins (CWPs) and the transport of CWPs into encystation-specific vesicles (ESVs). Active vesicular trafficking is essential for encystation, but the molecular machinery driving vesicular trafficking remains unknown. The Rab proteins are involved...

A survey of the river water frequently used by the Temuan Orang Asli (aborigine) indicated that 66.7% of the river water samples were Giardia cyst positive and 5.6% were Cryptosporidium oocyst positive. Although Giardia cysts were detected in samples from all the sites (e.g. upstream, midstream, and downstream), Cryptosporidium was only present in one river water sample taken from downstream fr...

Giardiasis is a neglected disease that spreads worldwide from the Arctic [1] to the Tropics [2]. It affects nearly 2% of adults and 6% to 8% of children in developed countries worldwide. Nearly 33% of people in developing countries have had giardiasis [3]. The disease is caused by a binucleated flagellated protozoan parasite Giardia lamblia (synonyms: G. intestinalis and G. duodenalis) that inh...
