Introduction: The present work aimed to assess the anti-parasitic effects of limonene (LMN) against Giardia lamblia trophozoites and cysts. Methods: Anti-Giardia activities LMN (25, 50, 100 μg/mL) were assessed G. cysts for 15-360 minutes. on apoptosis stimulation parasites determined by colorimetric protease assay. Results: more sensitive than best effect was seen at μg/mL. markedly triggered ...

The protozoan parasites Giardia and Cryptosporidium have been described as important waterborne disease pathogens, and are associated with severe gastrointestinal illnesses. The objective of this paper was to investigate the presence of Giardia cysts and Cryptosporidium oocysts in samples from watershed catchments and treated water sources. A total of 25 water samples were collected and examine...

An aquatic biomonitoring of Giardia cysts and Cryptosporidium oocysts in river water corresponding to five villages situated in three states in peninsular Malaysia was determined. There were 51.3% (20/39) and 23.1% (9/39) samples positive for Giardia and Cryptosporidium (oo)cysts, respectively. Overall mean concentration between villages for Giardia cysts ranged from 0.10 to 25.80 cysts/l whils...

introduction: giardia and cryptosporidium are two of the most common parasitic protozoa that cause acute intestinal infections in children, all of the world. these parsites find in water environments, such as untreated water , wastewaters and even treated water. according to, a precise study on surface water was not done, in our country, necessity of precise study by ifa method that is prescise...

During June 1996, water supplies of the city of San Pedro Sula, Honduras, were sampled to obtain an assessment of Cryptosporidium oocyst and Giardia cyst concentrations. Each sample was concentrated and stained with an indirect immunofluorescent antibody, and parasites were counted through microscopic analysis. In three surface water supplies, Cryptosporidium oocyst concentrations ranged from 5...

Giardia and Cryptosporidium have emerged as waterborne pathogens of concern. Thirty-one water samples were collected from nine potable water treatment plants in Taiwan and investigated for the presence of Giardia cysts and Cryptosporidium oocysts. The immunofluorescence assay was used for the simultaneous detection of cysts and oocysts. The frequency of occurrence of cysts was 77.8% for Giardia...

The purpose of our study was to investigate the hematological status, vitamin B12 and folic acid absorption and intestinal pathology after Giardia lamblia infection in a rat model. Adult Wistar rats were assigned randomly to receive human giardia cysts orally in the amount of 5 x 10(5) or 1.0 x 10(6) cysts, or none in the controls. The results showed that all the rats injected with giardia cyst...

Cryptosporidium and Giardia are two important pathogenic parasites that have caused many waterborne outbreaks which affected hundreds of thousands of people. Contamination from effluent discharged by sewage treatment plants have been implicated in previous waterborne outbreaks of Cryptosporidium and Giardia. This study evaluated the reduction of Cryptosporidium and Giardia (oo)cysts in two sewa...

conclusions we concluded that ozonized organic extra-virgin olive oil was a growth inhibitor of giardia cysts, and concerning its compatibility with a biological system, it is recommended for further clinical trials. 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 interna...
