“…This finding could be described that in patients with considerable weight loss the HIV disease is more severe and defect of the immune system may involve the production of eosinophils (Arora and Arora 2009). Celiac was not confirmed in our patient, however celiac disease is one of the most frequent causes of malabsorption as reported previously (Behera et al 2008). Isosporiasis might manifest itself as a systemic disseminated infection in patients with AIDS, I. belli was detected within the cells of mediastinal, periaortic and mesenteric lymph nodes at autopsy (Restrepo et al 1987), and in gallbladder biopsy samples of a patient presenting with cholecystitis (Benator et al 1994).…”

“…It is generally assumed that malnutrition results from malabsorption caused by giardiasis-associated chronic diarrhea. Nutrient malabsorption has been reported for at least 50% of patients with symptomatic giardiasis (27,51,238). In addition, a negative effect of giardiasis on growth and weight gain has been commonly reported (11,186,209).…”

Zoonotic Potential and Molecular Epidemiology ofGiardiaSpecies and Giardiasis

2011

SUMMARY Molecular diagnostic tools have been used recently in assessing the taxonomy, zoonotic potential, and transmission of Giardia species and giardiasis in humans and animals. The results of these studies have firmly established giardiasis as a zoonotic disease, although host adaptation at the genotype and subtype levels has reduced the likelihood of zoonotic transmission. These studies have also identified variations in the distribution of Giardia duodenalis genotypes among geographic areas and between domestic and wild ruminants and differences in clinical manifestations and outbreak potentials of assemblages A and B. Nevertheless, our efforts in characterizing the molecular epidemiology of giardiasis and the roles of various animals in the transmission of human giardiasis are compromised by the lack of case-control and longitudinal cohort studies and the sampling and testing of humans and animals living in the same community, the frequent occurrence of infections with mixed genotypes and subtypes, and the apparent heterozygosity at some genetic loci for some G. duodenalis genotypes. With the increased usage of multilocus genotyping tools, the development of next-generation subtyping tools, the integration of molecular analysis in epidemiological studies, and an improved understanding of the population genetics of G. duodenalis in humans and animals, we should soon have a better appreciation of the molecular epidemiology of giardiasis, the disease burden of zoonotic transmission, the taxonomy status and virulences of various G. duodenalis genotypes, and the ecology of environmental contamination.

“…In endemic settings, infections tend to be milder as children get older, as the duration of the infection is shorter and the severity of disease decreases. As in young children, the elderly may also present with a more severe illness (8,11,42).…”

Update on Cyclospora cayetanensis , a Food-Borne and Waterborne Parasite

2010

View full text Add to dashboard Cite

SUMMARY The coccidian parasite Cyclospora cayetanensis is recognized as an emerging pathogen that causes protracted diarrhea in humans. The first cases of Cyclospora infection were reported in the late 1970s and were observed among expatriates and travelers in regions where infections are endemic. Since then, Cyclospora has been considered a cause of traveler's diarrhea. Epidemiological investigations were reported and examined in areas of endemicity even before the true identity of Cyclospora was elucidated. Cyclospora was fully characterized in the early 1990s, but it was not until the 1995 Cyclospora outbreak in the United States and Canada that it caught the attention of the public and physicians. The biology, clinical presentation, epidemiology, diagnosis, treatment, and control of cyclosporiasis are reviewed, with a focus on diagnostic assays currently being used for clinical and environmental samples. Challenges and limitations in working with Cyclospora are also discussed.
