Clinical and parasitological studies on pulmonary and hepatic hydatid cysts in hospitalized children and adults

A cross sectional study compared the clinical features of the pulmonary and hepatic hydatid cysts in children and adults and evaluated IHAT and ELISA techniques in diagnosis. The results showed that the patients ages were 5-14 years [10.6+/-3.7] in children and 16-75 years [32.2+/-14] in adults, patients 34 [75.5%] had liver cysts, 25 [55.5%] had pulmonary cysts and 7 [15.5%] had both liver and lung cysts. In hepatic hydatidosis, 7/34 [20.5%] cases were asymptomatic while others showed variable clinical manifestations. The commonest symptom was localized right hypochondrial pain in 13 [38.2%] and the least one was jaundice in 4 [11.7%]. The commonest sign was abdominal masses on the right hypochondrium in 88.2% and the least one was ascites in 5.8%.The commonest symptom of pulmonary hydatidosis was chest pain in 8 [34.7%] followed by cough and hemoptysis on 4 [17.3%] and the least one was cough and fever [8.6%]. Pulmonary hydatid cysts in children were significantly higher in males [17.3%] than females [4.3%], but without significance in adults [26% in male vs. 21.7% in females]. Sex difference in hydatid cyst frequencies between adults and children was significant [P <0.05]. Mixed hepatic and pulmonary cysts were less in children than in adults [14.3%vs 85.7%], with huge pulmonary cysts of 20 cm were more common in children [37.7%] than in adults [17.7%]. The high sensitivity [95.5%] of ELISA-IgG recommended this test showed a dependable sero-diagnosing one

Soil transmitted parasites in qualyobia governorate

The study determined the relation between prevalence of intestinal parasites and soil-transmitted parasites among households in Shiblanga representing a rural area of Qualyobia Governorate and Benha City representing an urban area of the same Governorate. The effect of soil's type on the intensity of parasites and to provide guidance on the prevention and control of soil transmitted parasitic infections for future studies in this field. This study was conducted at Benha City and Shiblanga village representing the urban and rural areas of Qualyobia Governorate. Geoparasites were investigated in-doors, around houses, in the fields and the streets from both areas. One hundred soil samples from Benha city and one hundred soil samples from Shiblanga village were collected each hundred soil samples was collected in the form of: 25 samples from the fields, 25 samples in-indoor yards, 25 samples the streets, 25 samples around houses. Approximately 200g soil was collected in plastic bags at 2-10 cm depth from different parts. Stool samples from households in same areas were collected after taken oral consent. All soil samples were screened for parasites using different parasitological methods [Zinc sulphate flotation, ether sedimentation technique, modified Baerman's apparatus and modified Berlese technique]. All stool samples were examined using direct smear, formalinether concentration techniques for detection of helminthes eggs, and modified acid- fast staining for detection of protozoa. The results showed that 86/200 soil samples were contaminated with different parasites, the prevalence rate of 43%. Soil samples from Shiblanga village showed higher level of parasitic contamination [56%] and Benha city showed a lower level of contamination by different parasites [30%]. Soil samples obtained from Manshiet El-Nour district, Benha revealed the highest level of parasitic contamination. While, in Shiblanga, El-Mansheya district revealed the highest level of parasitic contamination. Clay soil was the most type of soil contaminated by helminthes. The 10 houses out of 50 houses had the same parasites in the soil and in stool of their households, 8 houses in Shiblinga village and 2 houses in Benha city

Experimental study on respiratory cryptosprodiosis

Cryptosporidiosis has a worldwide geographical and zoological distribution. Cryptosporidium baileyi oocysts were isolated from the bursa of Fabricius [BF] of 4 weeks-old of 100 broilers. Twenty five broiler chicks of 2 day old free from cryptosporidial infection were inoculated intratracheally at a dose of 1 x 10[6] chicks. Five chicks were sacrificed at 4[th], 8[th], 12[th], 16[th], and 20[th] day postinoculation. Selected tissues from bursa of Fabricius, cloaca, colon, caeci and tracheas were taken and examined directly by scraping technique for endogenous stages. The distribution of C. baileyi in different tissues in the case of intratracheal inoculation; trachea 23 [92%] chicks infected, bursa of Fabricius 21 [84%] chicks, Cloaca 5 [16%] chicks, Colon 1 [4%] chick and the caeci showing no infection. Daily examination of the intratracheal droppings inoculation was done at the 5[th] day and lasted for 18-20 days, the patent period
