Avaliação dos conceitos sobre posse responsável exercida pela terceira idade em instituições não governamentais de Araçatuba-SP

Pets bring expressive benefits into the life of the elderly, so it becomes necessary to emphasize some of the concepts regarding responsible ownership consisting of a set of important attitudes that accounts for the well-being of all. In this context, non-governmental institutions represent an excellent mean of communication and information. Besides, the increase of the third aged people population indicates that a survey of parameters to this respect is necessary. Being thus, the objective of this work was to analyze the aged ones´ level of knowledge regarding their responsibility for their pet. A questionnaire was applied to 134 aged people, members of non-governmental organizations in the city of Araçatuba, SP, in order to find out how they took care of their pet animals. The pets aged from 2 to 336 months, being 43,3% mixed-breed animals. Out of that, 60,9% were male dogs and among cats, 65.2% were female cats. There was a 69.4% preference for dogs and a 17.9% preference for cats, only 10.5% of the elderly had preference for birds. From the descriptive statistics analysis it could be observed that 69.40% did not have any access to the street and that 50% did not have a veterinarian follow-up. Regarding vaccination it could be observed that 71.64% had received the rabies vaccine and 70.9% had received the combination vaccine. Also, 74.63% did not know the right moment to give medicines against animal worms. Another important fact was that 85.07% of the animals were not castrated and 84.91% were not under any preventive contraception method. In regard to food 50.75% of the animals were fed strictly with animal food, 12.69% with domestic food and 36.57% with both. Finally, 78.36% of the pets had never been ill. In this way, we can assure the importance of making responsible pet ownership measures well-known among third-aged people.

Índice de análise ambiental simplificado na avaliação de impactos nos recursos hídricos da bacia hidrográfica do Ribeirão do Meio, Leme, São Paulo, Brasil

This study evaluated environmental impacts at Meio Creek watershed, Leme, Sao Paulo, Brazil. A simplified environmental analysis index was applied correlating land use and occupation (vegetation elimination or modification, wildlife, color, smell, grease, oils, foams, larvae and red worms) with water quality parameters (conductivity, dissolved oxygen, pH and temperature). The simplified environmental analysis index showed that 27.8% visited places had a high or worrying environmental impact and 5.6% had a really high impact. As to the results of physical and chemical parameters, pH and conductivity values showed the conditions and standards that water Class 2 and 3 should have. These parameters were not the same for dissolved oxygen levels at most of the analyzed points. Despite the current environmental legislation at federal, state and municipal levels, Leme city does not have an effective environmental plan to control and protect springs and Meio Creek watershed and its tributaries.

Raphidascaris camura sp. n., Hysterothylacium eurycheilum (Olsen) comb. n. and Comments on Heterotyphlum Spaul (Nematoda: Ascaroidea) in Marine Fishes

Raphidascaris camura sp. n. infected the stomach and intestine of Pomatomus saltatrix (type host), from the northern Gulf of Mexico. It is characterized by having the following combination of features: 31 to 40 pairs of preanal papillae, 10 pairs of postanal papillae with the third papilla from the posterior extremity doubled, nearly equal spicules 1.8 to 2.7% of the body length, and lateral alae abruptly curved near their anterior extremity. Additional species of Raphidascaris were examined and are discussed. Hysterothylacium eurycheilum (Olsen, 1952) comb. n. (=Heterotyphlum e.) from Epinephelus itajara in Florida and the Lesser Antilles, previously known from female worms only, is redescribed as is the anterior end of Heterotyphlum himantolophi Spaul, 1927.

Avian Piscivores as Vectors for Myxobolus cerebralis in the Greater Yellowstone Ecosystem

Myxobolus cerebralis, the cause of whirling disease in salmonids, has dispersed to waters in 25 states within the USA, often by an unknown vector. Its incidence in Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri within the highly protected environment of Yellowstone Lake, Yellowstone National Park, is a prime example. Given the local abundances of piscivorous birds, we sought to clarify their potential role in the dissemination of M. cerebralis. Six individuals from each of three bird species (American white pelican Pelecanus erythrorhynchos, double-crested cormorant Phalacrocorax auritus, and great blue heron Ardea herodias) were fed known-infected or uninfected rainbow trout O. mykiss. Fecal material produced during 10-d periods before and after feeding was collected to determine whether M. cerebralis could be detected and, if so, whether it remained viable after passage through the gastrointestinal tract of these birds. For all (100%) of the nine birds fed known-infected fish, fecal samples collected during days 1–4 after feeding tested positive for M. cerebralis by polymerase chain reaction. In addition, tubificid worms Tubifex tubifex that were fed fecal material from known-infected great blue herons produced triactinomyxons in laboratory cultures, confirming the persistent viability of the parasite. No triactinomyxons were produced from T. tubifex fed fecal material from known-infected American white pelicans or double-crested cormorants, indicating a potential loss of parasite viability in these species. Great blue herons have the ability to concentrate and release viable myxospores into shallow-water habitats that are highly suitable for T. tubifex, thereby supporting a positive feedback loop in which the proliferation of M. cerebralis is enhanced. The presence of avian piscivores as an important component of aquatic ecosystems should continue to be supported. However, given the distances traveled by great blue herons between rookeries and foraging areas in just days, any practices that unnaturally attract them may heighten the probability of M. cerebralis dispersal and proliferation within the Greater Yellowstone Ecosystem.

Echinococcus Infections in Man and Animals in Kenya

1. Hydatid cysts are found in more than 30 per cent of all cattle, sheep and goats in Kenya, but the disease is prevalent in man only in the semi-desert area of Turkana. Up to the time of the present investigation the life-cycle of the parasite in East Africa had not been studied, but it was suggested that wild carnivores, such as hyenas and jackals, might be the main hosts of the adult worms. 2. One hundred and forty-three carnivores, representing 23 species, have been examined. Echinococcus adults were found in 27 out of 43 domestic dogs (Canis familiaris), in three out of four hunting dogs (Lycaon pictus), in one out of nine jackals (Thos mesomelas), and in three out of 19 hyaenas (Crocuta crocuta). 3. A detailed morphological study was made of the Kenya material. After comparison with specimens from other parts of the world, it was concluded that the only species occurring in Kenya was E. granulosus, but it is possible that the minor morphological and biological differences are evidence of distinct strains. Further laboratory studies are necessary to compare the parasite from man and animals in different parts of Kenya with material from elsewhere. 4. A search was made for larval hydatids in 92 ungulates representing 18 species, and in a miscellaneous collection of nearly 2,000 rodents and primates representing a further 31 species. Only one animal was positive, a wildebeest (Gorgon taurinus). 5. The infections in the wild carnivores were all very light; only domestic dogs were heavily infected. It is concluded that the main cycle of transmission in Kenya is between dogs and domestic livestock. 6. Turkana tribesmen are the most heavily infected people in Kenya, either because the strain of parasite is more pathogenic to man in that area, or, more probably, because of the intimate contact between children and the large number of infected dogs. A particularly dangerous custom in the area is the use of dogs to clean the face and anal regions of babies when they vomit or have diarrhea. No satisfactory explanation can be given for the rarity of the disease in man in many of the other areas of Kenya where hydatids are very common in domestic animals. 7. The control of the disease will depend upon an active health-education campaign, together with the destruction of all unregistered dogs and improvement in meat hygiene.
