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...

Exponential expansion of human populations and human activities within primate habitats has resulted in high potential for pathogen exchange creating challenges for biodiversity conservation and global health. Under such conditions, resilient habitat generalists such as black and gold howler monkeys (Alouatta caraya) may act as effective sentinels to overall ecosystem health and alert us to imp...

Giardiasis is the most common waterborne parasitic infection of the human intestine worldwide. The etiological agent, Giardia duodenalis (syn. G. intestinalis, G. lamblia), is a flagellated, binucleated protozoan parasite which infects a wide range of mammalians [1]. Approximately 280 million people worldwide suffering from symptomatic Giardia infection every year [2]. Giardia is a major cause ...

background : giardia lamblia and helicobacter pylori are two flagellate microorganisms that grow in duodenum and stom­ach. the aim of this study was to evaluate the prevalence of them in patients with dyspepsia and other gi disorders. methods: in this cross-sectional study, co-infection of above-mentioned agents was investigated in a group of 130 patients [me­dian age of 40 yr (range=11-79) inc...

giardia lamblia is one of the most common intestinal protozoan parasites infecting human in the world. the goal of this study was searching for in-vitro effect of folic acid and cobalamin on adhesion and growth of g. lamblia as two important mechanisms in the pathogenesis in tyi-s-33 medium. g. lamblia trophozoites were obtained by in- vitro excystation procedure. three groups of giardia tropho...

BACKGROUND The prevalence and risk factors for infection with enteropathogens in dogs frequenting dog parks have been poorly documented, and infected dogs can pose a potential zoonotic risk for owners. HYPOTHESIS/OBJECTIVES To determine the prevalence and risk factors of infection with enteropathogens and zoonotic Giardia strains in dogs attending dog parks in Northern California and to compa...

Safe drinking water is a top priority in preventing disease outbreaks and is of general concern to everyone. This study examines the occurrence of Cryptosporidium and Giardia in Hungarian drinking water supplies for the first time. A total of 76 raw and drinking water samples were examined using the U.S. EPA Method 1623. From these 15 of 34 (48.4%) raw water samples tested positive for Giardia ...

Attachment of Giardia lamblia trophozoites to enterocytes is essential for colonisation of the small intestine and is considered a prerequisite for giardia induced enterocyte damage. The precise mechanisms involved are still being debated and some earlier work has been performed in models of uncertain biological relevance. In this study, co-incubation of giardia with enterocyte-like differentia...

Giardia lamblia, an anaerobic, amitochondriate protozoan parasite causes parasitic infection giardiasis in children and young adults. It produces pyruvate, a major metabolic product for its fermentative metabolism. The current study was undertaken to explore the effects of pyruvate as a physiological antioxidant during oxidative stress in Giardia by cysteine-ascorbate deprivation and further in...
