parasitic profile among school children in El-Wadi El-Gadded Governorate, Egypt

Parasitic infection is still a serious public health problem in the world, especially in developing countries including Egypt. It represents a major cause of morbidity and mortality in childhood and among high-risk groups in most parts of the world. This study detected the prevalence of parasitic infection among school children in El-Wadi El-Gadded [the New Valley Governorate]. A total of randomly chosen 1615 students aged from 6-16 years, [771 males and 844 female] from 12 primary schools and 12 preparatory schools related to four centers [El Dakhala, El Farfra, Paris and Platt] from the New Valley Governorate. Each child was subject to: A questionnaire sheet, Urine examination through sedimentation methods, Stool examination using: Direct smear, Simple sedimentation method and Modified Ziehl-Neelsen Stain, Blood samples were collected randomly from 450 children and examined for Seropositivity of toxoplasmosis using [On-SiteToxoIgG/IgM Rapid Test-Cassette] and examination of hair and clothes for ectoparasites [lice]. The overall prevalence of parasites was [39.1%] among primary and preparatory school children. The helminthes were E. vermicularis [15.2% and 17. 1%]; A. lumbricoides [1.3% and 1.9%] and then H. nana [0.9% and 0.6%] and the protozoa were E. histolytica [14.1% and 13.2%], Giardia lamblia [3.8% and 309%], and then Cryptosporidium parvum [0.09%] and seropositivity of toxoplasmosis was in [3.0% and 2.7%] among primary and preparatory school children respectively. Mixed infection was in [0.4%] among primary school children. Head lice infestation was more prevalent among primary school children than preparatory school ones with a ratio [3.5% and 0.2%] respectively, was nil among males

Role of parasites among chronic diarrheic patients

This work studied the role of parasitic infection among 85 chronic diarrheic patients in Delta region and cross-matched 20 normal controls. They were subjected to thorough history taking and clinical examination and stool examination by direct smear, formol-ether concentration, simple sedimentation, simple floatation and Kato-katz thick smear. Questionnaire sheet was obtained for each case included personal history, complaint, present as well as past history and family history. The results showed that 67.1% of patients suffered from parasites versus 20% in controls. They included giardiasis mixed with hymenolepiasis nana, ameobiasis; ascariaisis, S.mansoni, heterophyiasis, B. hominis, Taenia spp and enterobiasis respectively. Single infection represented 54.2 %, while mixed ones were 12.9% of total chronic diarrhea cases and non-parasitic causes were responsible for 32.9%. Mixed infection was common in A. lumbricoides with E.histolytica [18.18%] and H. nana with G. lambia [27.28%]. The diarrhea duration was longer in mixed infections [3 months], E.histolytica [2 months] and H.nana [1.5 months]. Commonest symptom other than diarrhea was abdominal pain mainly in mixed parasitosis. Parasitic diarrhea was more common in males than females [1.28: 1]. Chronic parasitic diarrhea was most prevalent among low social class [49 or 57.6%] followed by very low social class [20 or 23.5%], middle social class [10 or 11.7%] and finally high social class [6 or 7.1%] with significant increase in low social class as compared to high one, and most prevalent among positive cases in rural area than in urban area

Histopathological, histochemical and biochemical studies on hepatic hydatid cysts of some animals

Cystic echinococcosis is considered as a major cosmopolitan zoonotic disease affecting the health of man. Naturally infected hepatic cysts from camels, pigs, and sheep were collected from El-Basateen abattoir for histopathological, histochemical and biochemical, studies. Total proteins, uric acid, urea, cholesterol, triglycerides, AST, ALT, GOT, Alkaline phosphatase LDH, Na, K, and calcium showed a higher concentration in fertile cysts while creatinine only had a higher concentration in sterile ones. Dystrophic changes were observed in the infected liver specially around the cyst wall and around the portal areas this was accompanied with increased collagenous fibres. The cyst wall showed remarkable reaction for total proteins in camels and pigs associated with less stain affinity in the hepatocytes. A remarkable reaction for polysaccharides was detected in the cyst wall of all the studied animals comparing to hepatocytes
