Two cross-sectional studies were conducted, in 2002 (N=379) and 2003 (N=397), to estimate the prevalence of intestinal parasites among children at five municipal daycare centers in Botucatu, State of São Paulo. Socioeconomic, sanitary and educational data were collected and parasitological tests were performed on feces. Giardia duodenalis presented prevalence of 23.7% (2002) and 21.4% (2003) fo...
UNLABELLED The immune system has numerous mechanisms that it can use to combat pathogens and eliminate infections. Nevertheless, studies of immune responses often focus on single pathways required for protective responses. We applied microarray analysis of RNA in order to investigate the types of immune responses produced against infection with the intestinal pathogen Giardia duodenalis. Infect...
Background and aims: We investigated the children of Parana State, Brazil the prevalence of intestinal parasitosis and the associated factors involved in the transmission of intestinal parasites, and we genotyped the Giardia duodenalis isolates obtained. Methods: Fecal samples were analyzed by established microscopic methods. G. duoden...

Giardia duodenalis is an intestinal protozoal parasite capable of causing both clinical and subclinical disease in a broad range of species, including humans and cats. The parasite has a ubiquitous distribution and infection occurs worldwide in nearly all mammals. Giardia infection in cats may not be associated with any clinical signs, but affected cats most commonly exhibit acute small bowel d...
Cryptosporidium and Giardia are major causes of diarrhoeal disease in humans, worldwide and are major causes of protozoan waterborne diseases. Both Cryptosporidium and Giardia have life cycles which are suited to waterborne and foodborne transmission. There are 16 'valid'Cryptosporidium species and a further 33+ genotypes described. Parasites which infect humans belong to the Giardia duodenalis...
Giardia duodenalis is one of the most prevalent intestinal protozoa infecting humans and domestic animals. The aim of this study was to identify subspecies of G. duodenalis by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method from fecal samples of naturally infected cattle in the Urmia, West Azerbaijan province, Iran. Overall, 246 fecal s...
A review of the Giardia duodenalis sequences currently available on the GenBank database was completed to compare the different genotyping loci (small subunit ribosomal DNA, glutamate dehydrogenase, triose-phosphate isomerase and beta giardin) for their ability to discern assemblage and subassemblage groups and infer phylogenetic relationships. In total, 405 Giardia duodenalis sequences were so...
BACKGROUND The flagellate protozoan Giardia duodenalis is an enteric parasite causing human giardiasis, a major gastrointestinal disease of global distribution affecting both developing and industrialised countries. In Spain, sporadic cases of giardiasis have been regularly identified, particularly in pediatric and immigrant populations. However, there is limited information on the genetic vari...
Giardia lamblia (syn. Giardia intestinalis, Giardia duodenalis) is an enteric protozoan parasite with two nuclei, and it might be one of the earliest branching eukaryotes. However, the discovery of at least rudimentary forms of certain features, such as Golgi and mitochondria, has refuted the proposal that its emergence from the eukaryotic lineage predated the development of certain eukaryotic ...
