ABSTRACT The aim of this study was to perform the molecular characterization of conserved and variable regions of feline calicivirus capsid genome in order to investigate the molecular diversity of variants in Brazilian cat population. Twenty-six conjunctival samples from cats living in five public short-term animal shelters and three multicat life-long households were analyzed. Fifteen cats had conjunctivitis, three had oral ulceration, eight had respiratory signs (cough, sneeze and nasal discharge) and nine were asymptomatic. Feline calicivirus were isolated in CRFK cells and characterized by reverse transcription PCR target to both conserved and variable regions of open reading frame 2. The amplicons obtained were sequenced. A phylogenetic analysis along with most of the prototypes available in GenBank database and an amino acid analysis were performed. Phylogenetic analysis based on both conserved and variable region revealed two clusters with an aLTR value of 1.00 and 0.98 respectively and the variants from this study belong to feline calicivirus genogroup I. No association between geographical distribution and/or clinical signs and clustering in phylogenetic tree was observed. The variants circulating in public short-term animal shelter demonstrated a high variability because of the relatively rapid turnover of carrier cats constantly introduced of multiple viruses into this location over time.

RESUMO Objetivo Avaliar o desempenho do equilíbrio estático e dinâmico de escolares ouvintes e com perda auditiva sensório-neural. Métodos Estudo de corte transversal que avaliou 96 escolares, sendo 48 ouvintes e 48 com perda auditiva sensório-neural, de ambos os sexos, na faixa etária entre 7 e 18 anos. Para a avaliação do equilíbrio estático, foram utilizados os testes de Romberg, Romberg-Barré e Fournier, e, para avaliar o equilíbrio dinâmico, foi usado o teste de Unterberger. Resultados Os escolares com perda auditiva apresentaram maior ocorrência de alterações no equilíbrio estático e dinâmico, comparados aos ouvintes, em todos os testes empregados (p<0,001). O mesmo foi observado quando os escolares foram agrupados pelos sexos. Para o sexo feminino, os valores de p para os testes de Romberg, Romberg-Barré, Fournier e Unterberger foram, respectivamente, p=0,004, p<0,001, p<0,001 e p=0,023; para o sexo masculino, foram p=0,009, p<0,001, p<0,001 e p=0,002. A mesma diferença foi observada quando os escolares foram estratificados pelas faixas etárias. Para aqueles de 7 a 10 anos, os valores de p foram, respectivamente, para os testes de Romberg, Romberg-Barré e Fournier p=0,007, p<0,001 e p=0,001; entre 11 e 14 anos, para os testes de Romberg, Romberg-Barré, Fournier e Unterberger, foram, respectivamente p=0,002, p<0,001, p<0,001, p=0,015; entre 15 e 18 anos, para os testes Romberg-Barré, Fournier e Unterberger foram, respectivamente, p=0,037, p<0,001 e p=0,037. Conclusão Os escolares com perda auditiva apresentaram maior ocorrência de alterações no desempenho do equilíbrio estático e dinâmico que os ouvintes, do mesmo sexo e faixa etária.

ABSTRACT Objective To assess the static and dynamic balance performance of students with normal hearing and with sensorineural hearing loss. Methods A cross-sectional study assessing 96 students, 48 with normal hearing and 48 with sensorineural hearing loss of both sexes, aged 7 and 18 years. To evaluate static balance, Romberg, Romberg-Barré and Fournier tests were used; and for the dynamic balance, we applied the Unterberger test. Results Hearing loss students showed more changes in static and dynamic balance as compared to normal hearing, in all tests used (p<0.001). The same difference was found when subjects were grouped by sex. For females, Romberg, Romberg-Barré, Fournier and Unterberger test p values were, respectively, p=0.004, p<0.001, p<0.001 and p=0.023; for males, the p values were p=0.009, p<0.001, p<0.001 and p=0.002, respectively. The same difference was observed when students were classified by age. For 7 to 10 years old students, the p values for Romberg, Romberg-Barré and Fournier tests were, respectively, p=0.007, p<0.001 and p=0.001; for those aged 11 and 14 years, the p values for Romberg, Romberg-Barré, Fournier and Unterberger tests were p=0.002, p<0.001, p<0.001 and p=0.015, respectively; and for those aged 15 and 18 years, the p values for Romberg-Barré, Fournier and Unterberger tests were, respectively, p=0.037, p<0.001 and p=0.037. Conclusion Hearing-loss students showed more changes in static and dynamic balance comparing to normal hearing of same sex and age groups.
