“…Likely reasons for this difference could be related to, low socioeconomic, cultural, climatic conditions, poor health hygiene and nutritional factors. 3,8 In this study boys with 16.29% had a higher rate than girls with 10.45%. Like our study in AlSaeed et al study the frequency distribution of Giardiasis was higher among boys (41.6%) than girls (35.6%).…”

“…6 All age groups are affected in epidemic areas but children are infected more frequently than adults. [7][8][9] The protozoan genus Giardia (Family Giardiidae, order Giardiida) contains at least six species that infect animals and/or humans. These species are distinguished on the basis of the morphology and ultrastructure of their trophozoite.…”

“…Studies have shown that the prevalence of intestinal parasitic infection is higher in younger people, especially children (Hellard et al 2000). For instance, in a large study of IPIs in Iran found children aged 2-14 years with a high prevalence of 25 % (Sayyari et al 2005).…”

Intestinal parasitic infections are endemic worldwide and have been described as constituting the greatest single worldwide cause of illness and disease. The prevalence of Intestinal parasitic infections was estimated to be 5.92 %. Entamoeba coli was the most common parasite followed by Giardia lamblia and Blastocystis hominis. About 5.15 % of samples contained a single parasite and 0.76 % contained multiple parasites. In this study, the prevalence of intestinal parasites especially helminthic infections was low. The study aimed to estimate prevalence of intestinal parasites in Eghbalieh city from Qazvin Province, Iran.

“…Partial immunity in developing countries is supported by children excreting the bacteria for shorter duration and by disproportionately higher risk in travellers [12]. In industrialized countries, the exposure to Campylobacter is considered much lower, which translates into lower incidence rates of campylobacteriosis in children and a lower percentage of carriers [11,13,14]. One of the few documented instances of acquired immunity to Campylobacter infection in industrialized countries is with people professionally exposed, such as poultry abattoir workers [15,16].…”

Do patients with recurrent episodes of campylobacteriosis differ from those with a single disease event?

BackgroundAlthough Campylobacter is the leading cause of reported bacterial gastro-enteritis in industrialized countries, little is known on its recurrence. The objective of this study is to describe the risk and the patient characteristics of recurrent episodes of human campylobacteriosis reported in Quebec.MethodsLaboratory-confirmed cases of campylobacteriosis reported in the province of Quebec, Canada, through ongoing surveillance between 1996 and 2006 were analyzed. The risk of having a recurrent episode of campylobacteriosis was described using life table estimates. Logistic regression was used to assess if gender, age and patient residential location were associated with an increased risk of recurrence.ResultsCompared to the baseline risk, the risk for a recurrent disease event was higher for a period of four years and followed a decreasing trend. This increased risk of a recurrent event was similar across gender, but higher for people from rural areas and lower for children under four years of age.ConclusionsThese results may suggest the absence of durable immunity or clinical resilience following a first episode of campylobacteriosis and periodical re-exposure, at least among cases reported through the surveillance system.

Prevalence of enteric pathogens among community based asymptomatic individuals

Abstract: Except for Giardia, pathogens were rarely found in asymptomatic individuals in the community. The prevalence of pathogens was higher in children than adults.
