Inactivation of Giardia lamblia and Giardia muris cysts was compared by using an ozone demand-free 0.05 M phosphate buffer in bench-scale batch reactors at 22 degrees C. Ozone was added to each trial from a concentrated stock solution for contact times of 2 and 5 min. The viability of the control and treated cysts was evaluated by using the C3H/HeN mouse and Mongolian gerbil models for G. muris...
There are no meta-analyses specifically describing the prevalence of zoonotic and non-zoonotic genotypes of Giardia intestinalis in cats, which would be useful in defining the importance of cats as a source of zoonotic transmission. We performed a systematic review of the literature in three databases (PubMed, Scopus and SciELO) to assess the proportion of cats that were infected with specific ...
Giardia lamblia is the most common intestinal parasite in the United States and is worldwide in distribution. l Approximately 4 percent of stool specimens submitted to public health laboratories in this country contain Giardia cysts.2 The usual symptoms of acute giardiasis include diarrhea, abdominal cramps, nausea, and weight loss. Many, if not most, individuals with Giardia infection are asym...
CONTEXT AND OBJECTIVE Giardiasis is common in Brazil. For laboratory diagnosis, the method most utilized is microscopic examination of fecal samples, but the immunoenzymatic method is also available. The aim of this work was to verify the advantages and drawbacks of immunoassaying versus microscopy for diagnosing Giardia lamblia, when a single fecal sample is analyzed. DESIGN AND SETTING Pros...
Giardia lamblia (G. lamblia)-filled pancreatic masses are a rarely reported entity. Furthermore, there are only a few case reports in literature on the association of these masses with cancer. We present a case of a G. lamblia-filled pancreatic cystic mass in a patient with a history of T-cell-rich B-cell lymphoma. The authors performed a PubMed search using (Medical Subject Headings) MeSH term...
Giardia lamblia (syn G. intestinalis, G. duodenalis) is the intestinal protozoan producing non-bacterial diarrhea most prevalent in the world. PCR genotype classification of Giardia in feces depends on the quality and quantity of purified DNA and the removal of a great number of inhibitors. The aim of this study was to adapt a PCR protocol to the amplification of the triosephosphate isomerase (...
BACKGROUND Among the most important parasitic disease, causing diarrhea, Giardia lamblia is noteworthy. Nowadays detection methods for these parasites include parasitological methods such as microscopic examination. The sensitivity of these methods relies on the expertise and experience of examiners. In contrast, molecular methods such as PCR are less dependent on the expertise of the examiner....
Giardia lamblia is an early branching eukaryote, and although distinctly eukaryotic in its cell and molecular biology, transcription and translation in G. lamblia demonstrate important differences from these processes in higher eukaryotes. The cyclic octapeptide amanitin is a relatively selective inhibitor of eukaryotic RNA polymerase II (RNAP II) and is commonly used to study RNAP II transcrip...
Co-infection may affect transmission and recovery from infection, but remains an understudied element of disease ecology, particularly with regard to antagonism between parasites sharing a host. Helminth and giardia infections are often endemic in the same populations and both occupy the small intestine; yet few studies have examined interactions between these parasites. We report on helminth-g...
