“…Rey (1992) suggested that the pathological nature of the parasitism is incidental, with the occurrence of the lesions not being constant with an energetic loss by the host. This apparent absence of impairment for the host can indicate a relationship between the anuran and the parasite that is a result of a long period of coevolution, with reciprocal adjustments and equilibrium (Cheng, 1964;Ávila-Pires, 1989). However, we must also consider that the host may be injured at physiological levels not detectable in the present study (e.g.…”

Summary :We studied some parameters of the parasitism by the mite Hannemania sp. on the endemic frog Hylodes phyllodes in the Atlantic Forest of Ilha Grande (Rio de Janeiro State, Brazil). Prevalence, mean abundance, mean intensity and total intensity of infestation, body regions infected, and host sexual differences in parasitism rate of the larvae of Hannemania sp. on individuals of H. phyllodes were assessed. Prevalence was 86.5 % (N = 37; total of 1,745 larvae of Hannemania sp) for male hosts and 91.7 % (N =12; total of 330 larvae) for female hosts, with no significant difference between the sexes. Overall prevalence of Hannemania sp. on H. phyllodes was 87.7 %. Mean intensity of infestation in males (54.5 ± 42.5; range 1-173 larvae) was higher than in females (29.9 ± 47.6; range 1-166). We conclude that the rates of intensity, abundance, and prevalence of Hannemania larvae parasitizing Hylodes phyllodes at Ilha Grande were considerably high, suggesting that this species of anuran constitutes a relevant host for this mite species to complete its lifecycle in the area. Differences between males and females in infestation rates probably reflect their differential use of space in the forest.

“…A densidade destes animais está interligada a fatores sócio-econômicos, os quais são característicos e peculiares nos diferentes grupos populacionais (4) . Tem-se que considerar que a densidade populacional de cães não domiciliados varia de região para região, ou seja, quanto pior for a condição social de uma região, maior tende a ser a sua população de cães não domiciliados (40,41) . O ambiente também vai influenciar já que, quanto maior a possibilidade de abrigo, água e alimentos, maiores serão as condições de sobrevivência e, consequentemente, maiores as populações nas ruas (4) .…”

ResumoNa maior parte dos municípios brasileiros há superpopulação de cães não domiciliados, os quais trazem problemas associados à ordem urbana, ao meio ambiente e à saúde coletiva, além de sofrerem maus-tratos. Nesse contexto, vislumbra-se a necessidade do desenvolvimento de ações de controle populacional desses animais. O objetivo do presente trabalho foi conhecer a percepção dos atores sociais, como gestores dos órgãos responsáveis pelas ações de controle, gestores de organizações não governamentais de proteção animal e população em geral em relação à qualidade de vida e o controle populacional dos cães não domiciliados. Foram aplicados questionários estruturados a amostras desses três grupos e os dados foram trabalhados com técnicas de estatística descritiva e comparação de frequência. Os resultados permitiram concluir que a percepção da sociedade sobre o controle populacional e a qualidade de vida desses animais guardam importantes diferenças sob a ótica dos três grupos avaliados, mas apresentam, também, semelhanças importantes, em especial no tocante à percepção sobre a responsabilidade pelo desenvolvimento de ações de controle populacional, à aceitação da utilização de recursos públicos destinados à saúde pública nas ações de controle, à qualificação como grande a densidade populacional e à má qualidade de vida desses animais. Palavras-chave: cão não domiciliado; controle populacional; percepção social. AbstractIn most Brazilian municipalities there is an overpopulation of stray dogs, which causes problems to the urban order, the environment and the public health, in addition to mistreatment to these dogs. In such context we foresee the need of developing actions targeting the population control of these animals. This essay aims at knowing the perception of social actors, such as managers of entities responsible for control actions, managers of NGOs working with animal protection and population in general with respect to the life quality and population control of stray dogs. Questionnaires were used on samples of individuals of these three groups and the data thereof were analyzed with descriptive statistics techniques and frequency comparison. The results allowed us to conclude that the society's perception of population control and life quality of these animals bear important differences under the viewpoint of the three evaluated groups; however, they also bear significant similarities, especially with respect to the perception of the responsibility for the development of population control actions, the acceptance of using public funds intended to public health in control actions, the classification of Cienc. anim. bras., Goiânia, v.16, n.4, p. 574-588 out./dez. 2015Percepção da sociedade sobre a qualidade de vida e o controle populacional de cães não domiciliados 575 such population density as large and the poor life quality of these animals.

“…A zoonosis occurs when these conditions appear. But if the alteration is so great that the parasite becomes totally specific to the new host 9,90 , the outcome could be similar to HIV infection 76 . This may be McMICHAEL 80 argues that the historical transitions experienced by our prehistoric ancestors when they climbed down out of the trees onto the savannahs, incorporated meat into their diet, and more recently since the emergence of Homo sapiens, the development of agriculture, and the conquest of new territories and civilizations favored the emergence of (and exposure to) infectious agents of animal origin.…”

SuMMaRYThe authors present a review of records of intestinal parasitic helminths from animals in human archaeological remains, reported since the emergence of paleopathological studies. The objective was to relate paleoparasitological findings to geographic, biotic, and abiotic factors from the environment in which the prehistoric populations lived, and understand some aspects related to the process of human dispersion and biological and cultural evolution. Modification of eating habits and the incorporation of new cultural practices are analyzed from the perspective of zoonoses from prehistory to the present day, especially in Brazilian indigenous populations. Three tables identifying the helminths, their natural hosts, dates, and sites of archaeological findings complete this review. In conclusion, various zoonoses known today have occurred since antiquity, and these data, combined with studies on the emergence and reemergence of diseases, could make possible to compose scenarios for the future.
