Imported malaria in United Arab Emirates: evaluation of a new DNA extraction technique using nested PCR.

Local malaria transmission in the United Arab Emirates (UAE) came to an end in 1997. Nevertheless, UAE has been subjected to substantial importation of malaria cases from abroad, concerning both UAE nationals and immigrants from malarious countries with a total number of 2,119 cases in 2007. To evaluate a new DNA extraction technique using nested PCR, blood samples were collected from 132 individuals who presented to Infectious Diseases Department in Rashid Hospital, Dubai, and Central Department of Malaria Control with fever and persistent headache.

Genetic characterization of Giardia lamblia isolates from Egyptian patients with relation to clinical giardiasis.

Investigators tried to correlate clinical presentation of giardiasis to the different genotypes, but controversial data were described through the last decade. The clinical manifestations of 89 Giardia patients were classified into:- GI: 52 symptomatic patients and GII: 37 asymptomatic patients. Genetic characterization of G.

Hydatidosis granulosus in Egyptian slaughtered animals in the years 2000-2005.

Hydatidosis was investigated among camels, sheep, goats, and pigs in Egyptian official abattoirs, from August 2000 to August 2005, and among cows and buffaloes were in Mansoura official abattoirs, in the year 2005. One hundred randomly chosen animals of each species were subjected to serologic and histopathologic examinations for infections. The overall five years hydatidosis prevalence was 2.

Intestinal parasites in Dakahlia governorate, with different techniques in diagnosing protozoa.

A total of 3180 patients attending Mansoura University Hospitals' Clinics, were subjected to stool examination by direct wet smear, formol-ether concentration, original formol-tween concentration, modified formol-tween concentration, modified Sheather's sugar floatation, Potassium hydroxide concentration and Gomori's Trichrome stain, and modified Kinyoun's acid-fast stain, and Ryan's Trichrome blue stain for Microsporidia. The intestinal helminthes in a descending order of abundance were: S. mansoni (5.

The reflection of control programs of parasitic diseases upon gastrointestinal helminthiasis in Dakahlia Governorate, Egypt.

The study area included Mansoura city as an urban area and Gogar village as a rural area. One thousand individuals were randomly selected from each area. Different methods of stool examination, perianal swab and urine examination of all participants revealed that the incidence in Mansoura city was in a descending order Heterophyes heterophyes 6.

Evaluation of seven assays detecting serum immunoglobulin classes and subclasses and salivary and faecal secretory IgA against Fasciola excretory/secretory (ES) antigens in diagnosing fascioliasis.

Seven assays detecting serum IgM, IgG, IgG1, IgG4, IgA and salivary and fecal excretory IgA against Fasciola excretory/secretory (ES) antigens were evaluated in diagnosing fascioliasis, for cross reactivity with Schistosoma mansoni sera and for evaluation of cure of Fasciola infection after treatment. Assays detecting sera IgM, IgG1, IgG4 and IgA against Fasciola ES antigens showed 100% specificity and sensitivity. Assays detecting IgM and IgG showed 98% and 96% sensitivity and 100% and 94.
