Prevalence of endo-parasites of common tree frog (Rana Saharica) from Misurata, Libya

The current study was conducted to detect the prevalence of parasitic infection among (62) common tree frogs (Rana Saharica), of different ages, with weights ranged between 1 and 25g. Results: The results revealed that 61 (98%) out of 62 examined common frogs were infected with endo-parasites. The prevalence of infection with protozoal was (86.4%) and (80%) for helminthes, while the mixed infection with both was 65%. Furthermore, the nematodes (75.5%) were the most prevalent helminthes, also helminthes mixed infection in a single host was reported. Rhabiditis spp., Ophiotaenia ranae, Glypthelmins quieta, Corynosoma spp. were Recovered from the digestive tract of common tree frogs, whereas, the Oplina ranarum and Copromonas subtillis the most prevalent protozoan species were detected from the common frogs. From the parasitic fauna seen in this study and from the statistical analysis, there were significant differences (P=0.05) between the weight of hosts and the density of infection

PREVALENCE OF PARASITIC CONTAMINATION OF LEAFY GREEN VEGETABLES IN MISURATA, LIBYA

This study was undertaken to determine the prevalence of parasitic contamination in leafy green (lettuce and rocket) vegetables, samples of which were taken up from different regions of Misurata, Libya. A total of 112 raw vegetable samples randomly selected from farms and markets were subsequently examined by a concentration method and then assayed by light microscopy. It was found that 56.3% of the green vegetables were contaminated with different intestinal parasites, the parasites included cysts of Giardia spp., Enatmeaba histolytic a, Entameaba coli , Coccidia spp. oocysts, Balantidium coli and eggs of Hymenolepis nana., Ascaris lumbricoides., Toxocara spp., Strongyloides spp., Trichius trichura and Trichostronylus spp. The highest rate of contamination was detected in rocket (64.3%) while contamination was lower in green lettuce (48.2%). Toxocara spp. eggs were the highest prevalent parasite detected in green vegetables (27%) with the highest score density found in the rocket. Toxocara was followed by Entameaba coli cysts (24%), Coccidia spp. Oocysts (22%), Enatmeaba histolytica cysts (19%), Giardia spp. cysts (10%), and Hymenolepis nana eggs (8%). There were lesser rates of contamination from the parasites Strongyloides spp., Trichius trichura and Trichostronylus spp. There was no significant difference between single and mixed contamination of rocket and lettuce P>0.05. However, there was a statistical difference between protozoa and helminths contamination of rocket and lettuce (P≤0.01). We conclude these findings may have important implications for global food safety and confirm that green vegetables are a point of transmission of intestinal parasites to humans and so are a threat to public health in Misurata, Libya
