Wildlife and environmental health: raccoons as indicators of zoonoses and pollutants in southeastern United States.

Inasmuch as terrestrial fauna are an integral part of our natural environment and are directly exposed to disease and pollutants, it follows that certain wild populations could serve to detect subtle alterations within ecosystems. A collection of studies on raccoons is presented to stimulate other researchers to develop the potential of our wildlife resources as monitors of environmental health. Raccoons have been used as serologic sentinels for St Louis encephalitis and Venezuelan equine encephalomyelitis. Studies suggest that the raccoon may be used as an indicator of leptospirosis, tularemia, and some enteric bacteria and viruses. Base line surveys have defined (1) residue levels of organochlorine and organophosphate compounds and (2) body burdens of mercury, cesium-137, and strontium-90. Physiologic responses, parasite burdens, and reproductive processes are also considered as measures that may reflect pertinent information about environmental health.

Knowledge, attitude and practices about zoonoses with reference to Campylobacteriosis in a rural area of West Bengal.

Campylobacteriosis is a leading cause of zoonotic diarrhoea in the developed as well as developing countries. Domestic animals particularly the poultry act as a source of human infections. Domestic animal rearing is a very common practice in India particularly in rural areas. The present study of KAP of Zoonosis showed 68.2 % of 500 families interviewed did not have knowledge about zoonotic diseases in rural Bengal and not a single family had any idea of Campylobacter infections.

Current status of food-borne parasitic zoonoses in Singapore.

Parasitic infections adopt a rather low profile in the highly urbanized setting in Singapore. Very few food-borne parasitic infections are encountered. Apart from a few reports of infections with Clonorchis/Opisthorchis, Taenia spp. and hydatid disease, there are no other citations of such helminthic infections. Seroprevalence surveys have shown the presence of toxoplasmosis in local meat animals (sheep, pigs and cattle) and Toxoplasma strains have been isolated from the pig, tree shrew (Tupaia glis), slow loris (Nycticebus coucang) and guinea pigs. Human toxoplasmosis is prevalent in Singapore. Anti-Toxoplasma antibodies are found in the normal population as well as in clinical cases (cervical lymphadenopathy, ocular disease and congenital toxoplasmosis). Carcasses/organs from meat animals (sheep, pigs, cattle) slaughtered at local abattoirs were examined for parasites. The main parasites found were Ascaris suum, Dictyocaulus, Metastrongylus, Cysticercus ovis, Fasciola hepatica and Sarcocystis spp. Pigs were also examined for trichinosis and, thus far, these have all been negative.

Current status of food-borne parasitic zoonoses in Laos.

Stool samples from a total of 1,008 persons were examined for intestinal parasites during a comprehensive study on the epidemiology of small fluke infections in Laos. The prevalence of small fluke eggs in the stool was seen to peak at age 20 years, particularly in men from villages (90.4%). Three quarters of infections belong to the category of light infections and only 0.6% to the category of very heavy according to eggs per gram of feces (EPG). The highest EPG was in the 11-15 year age group. In addition, the following parasites were diagnosed: Sarcocystis hominis (prevalence more than 10% in the group over 20 years of age), Taenia sp. (12.4% for the village people over 20 years), Fasciolopsts buski (3.8% for the same group). The habit of Laos people to eat raw fish, beef and pork flesh, is reflected in significant epidemiological consequences. Cercariae of Opisthorchis viverrini occurred in 0.5% of Bithynia siamensis goniomphalus examined, Haplorchis sp. cercariae were found in 0.9% of Tarebia granifera snails. Metacercariae of O. viverrini were found in flesh of 7 species of cyprinid fish. Haplorchis taichui in 4 species of these fish, and H. pumilio of two cyprinid species. Hampala macrolepidota harbored larvae of all above mentioned species. Stellantchasmus falcatus was recovered in fins of belonid fish Xenentodon cancila. Adults of O. viverrini were found in 36% of domestic and stray cats, Heterophyid flukes were found in 24% cats. The most frequent species were H. taichui and H. yokogawai. Eight Laotian students were treated in Czechoslovakia with praziquantel to determine fluke infection. Three were infected only by O. viverrini, four only by H. taichui and one by both O. viverrini and H. taichui. These results demonstrate the problem of correct differential diagnosis of food-borne small fluke infections and the need to assess the clinical course and public health aspects of infections.

Current status of food-borne parasitic zoonoses in Taiwan.

More than 50 species of zoonotic parasites (nematodes-18 spp., trematodes-19 spp., cestodes-10 spp., protozoa-2 spp., and arthropods-2 spp.) have been reported in Taiwan. Among them, Angiostrongylus cantonensis, Clonorchis sinensis and Taenia saginata are the most important and most common food-borne parasites. Angiostrongyliasis is highly endemic in southern and eastern Taiwan. About 80% of patients are children below 15 years of age, mostly infected after eating Achatina fulica during May and September. Patients residing in the mountainous and remote areas are more susceptible than those in the urban districts. Cipangopaludina chinensis and Ampullarium canaliculatus are additional important sources of infection. Albendazole is effective in treating infections in animals. Levamisole has been shown to shorten and lighten the course and symptoms in clinical trials. Clonorchiasis is endemic in Miao-li in northern, Sun-moon lake in central, and Mei-nung in southern Taiwan. Recent surveys, however, have shown endemic areas to be more extensive. Hakkanese and farmers have a greater tendency of infection than other groups. Praziquantel, 3 doses of 20 mg/kg body weight for one day, is an effective treatment. Taeniasis saginata is mainly caused by eating raw beef or viscera of wild animals by the aborigines. A single dose of 150 mg praziquantel cures almost 100%.

Neurologic aspects of North American zoonoses.

Neurologic dysfunction is a frequent presentation or complication of zoonotic infections. The differential diagnosis is broad and will include nonzoonotic diseases as well. Patterns of neurologic findings, systemic signs of infection, and epidemiologic risk factors are useful in the approach to diagnosis and initial empiric treatment of the patient with suspected zoonotic infection. Associations between these patterns and specific organisms are emphasized by means of tables and algorithms.

Tick-borne zoonoses: Lyme disease, ehrlichiosis, and Rocky Mountain spotted fever.

The primary health risk for veterinary staff and companion pet owners is exposure to ticks in the wooded/pasture areas or to ticks brought indoors by their pets. There are no proven cases of direct animal to human transmission for Lyme disease, ehrlichiosis, or Rocky Mountain spotted fever. Direct inoculation of blood from a bacteremic animal, eg, by needle stick is a theoretical, but, so far, undocumented health risk. However, veterinarians should record needle sticks or other inoculation-type injuries that occur in their practices. Prevention of Lyme disease, ehrlichiosis, Rocky Mountain spotted fever, and other tick-borne diseases depends on the avoidance of tick-infested areas and proper use of repellents and acaricides.
