E-mail: pviannavet@gmail.com Toxocara cati is one of the major intestinal parasites of cats and has great importance in public health as zoonotic agent of Visceral and Ocular Larva Migrans in humans. Studies to eliminate the infectious forms of this helminths are scarce. The aim of this study was to evaluate the action of various disinfectant solutions on the development of eggs of T. cati viability and infectivity of larvae present in the eggs of this parasite. Eggs were obtained from the dissection of female T. cati, recovered from infected cats. These were suspended in distilled water and divided into five groups with six replicates, each with about 3300 eggs. Each group was exposed for one hour at one of four selected commercial disinfectants and a control, and then washed with distilled water for removal of disinfectant solutions. All samples were assessed for development of eggs on days 0, +3, +6, +9, +12, +15, +18, +21 and +24. At the end of the observation period, 30 mice were infected with the samples. After 15 days the mice were euthanized and the brain, liver, lungs and kidneys, and carcass, macro-and microscopically observed. From day +6 eggs exposed to different treatments showed larva inside. And even after 24 days of exposure, the disinfectants were not able to inhibit the development or eliminate the larvae. The number of larvae recovered from infected mice showed that migration was observed in all animals. The carcass showed better recovery between the tissues analyzed. In no animal treated larvae were seen in the brain. No disinfectantused was able to inhibit embryogenesis of eggs of T. cati after one hour of exposure. The degree of infectivity and the migration pattern of the larvae was maintained even after treatment with disinfectants. |

Estudos para eliminar as formas infectantes deste helminto são escassos. O objetivo do presente estudo foi avaliar a ação de diferentes soluções desinfetantes sobre o desenvolvimento de ovos de T. cati e a viabilidade e infectividade de larvas presentes em ovos deste parasito. Os ovos foram obtidos a partir da dissecação de fêmeas de T. cati, recuperadas de gatos comprovadamente infectados. Estes foram suspensos em água destilada e divididos em cinco grupos com seis repetições, cada qual com aproximadamente 3300 ovos. Cada grupo foi exposto por uma hora, a um dos quatro desinfetantes comerciais selecionados e um controle, e em seguida lavados com água destilada para eliminação das soluções desinfetantes. Todas as amostras foram avaliadas quanto ao desenvolvimento dos ovos, através de alíquotas de 25µL observadas em microscópio óptico, nos dias 0, +3, +6, +9, +12, +15, +18, +21 e +24. Ao final do período de observação, 30 camundongos foram infectados com as amostras obtidas. Após 15 dias os camundongos foram eutanasiados e o cérebro, fígado, pulmões e rins, além da carcaça, observados macro e microscopicamente. A partir do dia +6 os ovos expostos aos diferentes tratamentos apresentaram larva no seu interior. E mesmo na avaliação do dia +24, os desinfetantes não foram capazes de inibir o desenvolvimento ou eliminar as larvas. O número das larvas recuperadas dos camundongos infectados demonstrou que houve migração larvar em todos os animais. O tecido que apresentou melhor recuperação entre os grupos foi a carcaça. Em nenhum animal tratado foram visualizadas larvas no cérebro. Nenhum desinfetante utilizado foi capaz de inibir a embriogênese dos ovos de T. cati após uma hora de exposição aos produtos. O potencial de infectividade e o padrão de migração das larvas foi mantido mesmo após o tratamento com os desinfetantes.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2012-12-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/765Brazilian Journal of Veterinary Medicine; Vol. 34 No. Supl.1 (2012); 31-40Revista Brasileira de Medicina Veterinária; v. 34 n.
