Review of Parasitic Zoonoses in Egypt

This review presents a comprehensive picture of the zoonotic parasitic diseases in Egypt, with particular reference to their relative prevalence among humans, animal reservoirs of infection, and sources of human infection. A review of the available literature indicates that many parasitic zoonoses are endemic in Egypt. Intestinal infections of parasitic zoonoses are widespread and are the leading cause of diarrhea, particularly among children and residents of rural areas. Some parasitic zoonoses are confined to specific geographic areas in Egypt, such as cutaneous leishmaniasis and zoonotic babesiosis in the Sinai. Other areas have a past history of a certain parasitic zoonoses, such as visceral leishmaniasis in the El-Agamy area in Alexandria. As a result of the implementation of control programs, a marked decrease in the prevalence of other zoonoses, such as schistosomiasis and fascioliasis has been observed. Animal reservoirs of parasitic zoonoses have been identified in Egypt, especially in rodents, stray dogs and cats, as well as vectors, typically mosquitoes and ticks, which constitute potential risks for disease transmission. Prevention and control programs against sources and reservoirs of zoonoses should be planned by public health and veterinary officers based on reliable information from systematic surveillance.     

Infection and invasion of humans in the Yamal Peninsula

The helminthic fauna of vertebrates in the Yamal peninsula consists of 61 species: of them 2 species are monogenic, 6 are trematodes, 29 are cestodes, and 24 are nematodes. Twelve species of the 4 are antroponoses and 8 are zoonoses which may parasite on human beings. Human infection with some zoonoses is due to local habits of eating raw or undercooked meat of wild animals, domestic deers, and fish. These helminthic diseases include trichinosis, taeniasis, opisthorchiasis, diphyllobothriasis. On contacting with dogs and Arctic foxes, the population is infected with echinococciasis, alveococciasis, toxoplasmosis. The foci of brucellosis, anthrax, tularemia, leptospirosis, rickettsioses, rabies, and toxoplasmosis were notified in the Yamal peninsula. Intensive migration of the population contributes to the importation of new species of causative agents to the peninsula and to the deterioration of the situation of endemic invasions and infections. Thus, in-depth study of parasitic and natural focus-related diseases in this region becomes partially urgent now.

The food-borne trematode zoonoses of Vietnam

During the past couple of decades, numerous surveys for the occurrence and distribution of food-borne trematodes in Vietnam have been carried out. However, the majority of the data obtained have not been published in international journals, and therefore, the seriousness of these trematode parasitic zoonoses in the country has not been fully appreciated. To correct this, over 40 Vietnamese language reports and local publications were translated and organized as a status review for an international audience. The results show that such serious trematode zoonoses as clonorchiasis, opisthorchiasis, paragonimiasis and fascioliasis are common in many regions of Vietnam, and, in the case of fascioliasis and paragonimiasis, are increasing. Data on the species of intermediate hosts involved in the transmission of these zoonoses, and the effect of host sex and age on infection frequencies are presented, along with findings on food preference/behavior investigations. Finally, the authors present recommendations for further research to provide a more comprehensive picture of the status of these zoonoses, and to obtain the risk assessment information needed to design prevention and control programs.     

Parasitic zoonoses; public health and veterinary perspectives

The importance of parasitic zoonoses continues to increase on both local and global scales as interactions between people and animals become more frequent through global travel, intensification of agriculture, habitat devastation, and changes in world trade patterns. A current and real threat is the potential for a deliberate introduction of a zoonotic disease through the prospect of bioterrorism. Parasitic zoonoses represent significant problems in public health, animal agriculture and conservation, and the meat industry. There is an urgent need for integration of medical and veterinary services, continuous disease surveillance in both humans and animals, the teaching of zoonoses to medical doctors, and intensified research on zoonotic agents and diseases. The convergence of both public health and veterinary services currently represents a real challenge for managing zoonotic diseases.     

Distribution of trematodes in snails in ponds at integrated small-scale aquaculture farms

In integrated small-scale aquaculture farming, animal and human excreta maybe used as fish feed and pond fertilizer, thereby enhancing transmission of fish-borne zoonotic trematodes (FZTs) from final hosts, like humans, pigs and chickens, to snails. Areas within a pond could vary in trematode egg-load due to the immediate bordering land, and this might provide implications for control of these trematodes or sampling in field studies measuring FZT prevalence in snails. We therefore estimated the effect of bordering land use on prevalence and FZT burden in snails in different areas within small-scale aquaculture ponds. Nine sampling areas within a pond were assigned in six ponds. For each sampling area, about 120 Melanoides tuberculata snails were collected. Based on land use bordering a sampling area, these were categorized in 5 risk-categories: low-risk (road, rice planted in pond, agriculture, or middle of pond), human access point to pond, livestock sty (pigs or poultry), both human access point and livestock sty, and water connection to canal. In total, 5392 snails were collected. Percentages of snails with parapleurolophocercous cercariae varied between 6% in areas categorized as low-risk and areas with livestock sty only to 15% in areas with both human access point and livestock sty; only this 15% was significantly different from the prevalence in the low-risk category. Percentages of snails with xiphidio cercariae did not differ between risk-categories and varied between 5% and 10%. Mean snail size was 15.2 mm, and was significantly associated with both the probability of infection as well as parasite burden. Very small differences in parasite burden were found at different land use areas; the maximum difference was about 11 cercariae. This study demonstrated only small differences between areas surrounding a pond on risk of snails to be infected with fish-borne trematodes within different pond areas. In field studies on FZTs in M. tuberculata snails in ponds, sampling from ponds can therefore be done without considering areas within ponds.
