Aspectos clínico-patológicos e imuno-histoquímicos de equídeos infectados pelo vírus da raiva

Foram analisados 14 equídeos (13 equinos e 1 muar) com diagnóstico clínico e histológico de raiva provenientes de quatro regiões do Brasil. O curso clínico médio foi de quatro dias de evolução, incluindo incoordenação motora, paralisia dos membros pélvicos, paresia dos membros torácicos e decúbito. Os achados histopatológicos caracterizaram-se por meningoencefalite e meningomielite não supurativa com infiltrado perivascular linfoplasmocitário. Corpúsculos de Negri foram observados em 64,28% (9/14) dos casos, principalmente na medula espinhal cervical e nos neurônios de Purkinje do cerebelo. Em 55,55% (5/9) dos equídeos analisados tiveram resultado positivo pela técnica de imunofluorescência direta para raiva. Todos os casos foram positivos na imuno-histoquímica para raiva, cujas reações foram mais evidentes no córtex temporal, córtex occipital e medula espinhal cervical. A técnica de imuno-histoquímica foi essencial para confirmar todos os casos de raiva nos equídeos.

Use of uniform designs in combination with neural networks for viral infection process development

This work aimed to compare the predictive capacity of empirical models, based on the uniform design utilization combined to artificial neural networks with respect to classical factorial designs in bioprocess, using as example the rabies virus replication in BHK-21 cells. The viral infection process parameters under study were temperature (34°C, 37°C), multiplicity of infection (0.04, 0.07, 0.1), times of infection, and harvest (24, 48, 72 hours) and the monitored output parameter was viral production. A multilevel factorial experimental design was performed for the study of this system. Fractions of this experimental approach (18, 24, 30, 36 and 42 runs), defined according uniform designs, were used as alternative for modelling through artificial neural network and thereafter an output variable optimization was carried out by means of genetic algorithm methodology. Model prediction capacities for all uniform design approaches under study were better than that found for classical factorial design approach. It was demonstrated that uniform design in combination with artificial neural network could be an efficient experimental approach for modelling complex bioprocess like viral production. For the present study case, 67% of experimental resources were saved when compared to a classical factorial design approach. In the near future, this strategy could replace the established factorial designs used in the bioprocess development activities performed within biopharmaceutical organizations because of the improvements gained in the economics of experimentation that do not sacrifice the quality of decisions.

Epidemiological aspects of dog bites considering biter dogs and victims

The aim of this study was to characterize dog bites using data on biter dogs and victims. An exploratory cross-sectional study was performed using 203 records of individuals who had attended in public health services in 2009 in the municipality of Araçatuba, São Paulo, Brazil, after they had been bitten by a dog. Over 70% (92/129) of the biter dogs were male and most of them (71%) received as a gift. Dog owners reported companionship as the main reason for acquiring the dog. The victims who were children were predominantly male, while the victims who were elderly were predominantly female. Most children were bitten on the head/neck, while adults were bitten on the hands/feet and lower limbs (p<0.0001). The owner of the dog was known in 83.2% of cases. However, rabies observation of the biter dog following the attack was only reported in 59.4% of cases. Situations involving aggression were related to dogs having escaped from their home (18.7%) or roaming free on the streets (17.0%). The analysis of biting dog characteristics using information obtained from dog bite victims and biting dog owners can help direct the medical treatment for dog bite victims. Moreover, concepts of responsible dog ownership can reduce the occurrence of bites.

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.
