Sporicidal activity of some disinfectants against clostridium perfringens isolated from broiler poultry litter

Necrotic enteritis and the subclinical form of Clostridium perfringens infection in poultry are caused by C. perfringens type A, producing the alpha toxin, and to a lesser extent type C, producing both alpha toxin and beta toxin C and have become serious threats to poultry health. This study was undertaken to determine the activity of 4 commonly available disinfectants against C. perfringens spores after 5,7.5,10,15,30 and 60 minutes of contact under dirty conditions, Of the 4 products tested, calcium hypochlorite 1% and Germicidan KOK 4% achieved the required reduction in microbial viability [>/=10[3]-fold] for relatively long contact times of 30 min, under dirty [3% yeast] conditions, One product [Biosentury 904, 2% conc] achieved the required reduction in microbial viability [>/=10[3]-fold] for contact times of 10 minutes, while Prophyl 75,1% concentration. achieved the required reduction in microbial viability [>/=10[3]-fold] for contact times of 5minutes.Upon addition of formic acid 2% and urea 1% the required reduction improved for [Biosentury 904, 2% conc] and Prophyl 75,1% concentration and achieved after 5 minutes and after 7.5 minutes for Germicidan KOK 4% while calcium hypochlorite was not improved by addition of formic acid 2% or urea 1%. Application of surface test using the four disinfectants was used alone and in combination with formic acid 2% or urea 1% showed nearly the same results obtained in the suspension test

Parasitic infection among the outpatients of Dakahlia governorate with a correlation between amebiasis and intestinal schistosomiasis

4896 individuals from Dakahlia Governorate were examined for parasitic infections. S. haematobium was detected in 18.63%. The commonest parasite was S. mansoni followed by E. histolytica. A significant relationship between amoebiasis and intestinal schistosomiasis has been demonstrated. Possible mechanisms include mechanical intramucosal tissue damage produced by Schistosoma ova and an altered immunological responsiveness

Natural entamoeba histolytica infection in domestic animals and rodents in Dakahlia Governorate, Egypt

The prevalence of Entamoeba histolytica was estimated in 112 cows, 85 buffaloes, 57 sheep, 46 goats, 148 dogs and 224 rats. Natural infection was detected in one dog and 43 rats. The relatively high prevalence of amoebic infection in Rattus norvegicus [31.94%] suggests its possible epidemiological role in the dissimination of amoebiasis in Dakahlia Governorate

Helminth parasites of cats in Dakahlia, Egypt

In a survey on intestinal helminthes among stray cats in Dakahlia Governorate, Dipylidium caninum were the most predominant [43.1%], followed by Toxocara cati [38.5%], Haplorchis yokogawai [35.4%], Pygidiopsis genata [29.2%], Heterophyes heterophyes [21.5%], Prohemistomum vivax [15.4%], Echinochasmus perfoliatus [7.7%] and Hydatigera taeniaeformis [6.2%]. The potential dangers of these parasites to man are discussed

Filter paper blood specimens in the serological diagnosis of schistosomiasis

Serum and filter paper blood specimens collected from individuals infected with Schistosoma mansoni, Schistosoma haematobium or with both species were tried in the circumoval precipition test and the cercarien-Hullen reaction. Sera obtained by venipuncture were more reliable
