La rápida proliferación del vector en áreas de clima cálido y baja altitud, como el oriente y la amazonia boliviana, generó la necesidad de analizar la adaptabilidad del A. aegypti en zonas templadas, tal es el caso de los valles mesotérmicos de la ciudad metropolitana de Cochabamba. Objetivo: la evaluación entomológica se realizó en una muestra de 264 viviendas seleccionadas al azar en Abril del 2016. El área de estudio abarca zonas urbanas de seis municipios (Cercado, Sacaba, Colcapirhua, Tiquipaya, Quillacollo y Vinto) del departamento de Cochabamba. El diseño para el estudio fue epidemiológico, transversal de diagnóstico comunitario. Métodos: de la muestra referida, 100 viviendas se encontraron larvas de A. aegypti , que corresponde a un 38% de infestación larvaria y un Índice Breteau de 1,0. Las llantas, turriles y recipientes desechables son un factor de riesgo para la propagación y adaptación del vector en nuestra región. Resultados: los hallazgos confirman la dispersión del A. aegypti con algunas regiones con mayor prevalencia (zona sud de cercado urbano, Colcapirhua y Quillacollo en el valle bajo). También se evidenció por primera vez que la dispersión y colonización de larvas de A. aegypti en el área de estudio alcanzó una altura mínima de 2 538 m/s/n/m. y una altura máxima de 2 623 m.s.n.m. Conclusiones: La prevención y el control de A. aegypti , en la metrópoli de Cochabamba va a requerir un trabajo mancomunado integral e intersectorial enfocados en una estrategia de intervención de gestión socioambiental de corresponsabilidad y participación comunitaria, generando como resultado un Manejo Integrado del Vector.

The fast proliferation of the vector at warm weather and low altitude over the sea level, such as the Bolivian valleys (as Cochabamba city), generates the need to analyze the adaptability of A. aegypti . Objective: this study of comunitary diagnosis, was developed at the metropolitan area of Cochabamba city, it confirms an spread A. aegypti , shown by georeferences of identified focus of high prevalence (sud of the city, Colcapirhua and Quillacollo as a low valley). Method: For the first time this vector spread, reached between 2 538 to 2 623 meters over sea level. From 264 inspected houses over the city, 100 cases were found positive for A. aegypti (38%) (Breteau Index: 1,0). Results:According to the study, tires, barrels and small containers are a risk factor for the spread and adaptation of the vector in our region. Conclusions: Prevention and control of A. aegypti in the metropolis of Cochabamba will require an integrated and intersectoral joint work, focused on a strategy of intervention socio-environmental and community participation, generating results in an Integrated Vector Management.

RESUMO Objetivou-se comparar a qualidade de espermatozoides recuperados a fresco e após refrigeração a 4ºC do epidídimo de gatos domésticos utilizando-se os diluidores ACP-117c e Tris. Sessenta epidídimos foram distribuídos em seis grupos: 10 epidídimos a fresco com o Tris (T0h), 10 a 4°C/2h e recuperados com Tris (T2h), 10 a 4°C/4h e recuperados com Tris (T4h), 10 epidídimos a fresco com o ACP-117c (A0h), 10 a 4 °C/2h e recuperados com ACP-117c (A2h), 10 a 4°C/4h e recuperados com ACP-117c (A4h). Os complexos testículo-epidídimo (CTE) do controle não foram refrigerados. Os outros foram refrigerados a 4°C durante duas e quatro horas. Os epidídimos foram separados das demais estruturas, e os espermatozoides recuperados pela técnica de flutuação modificada. Os parâmetros cinéticos foram avaliados em um sistema computadorizado, e o vigor, a viabilidade, a concentração, a funcionalidade de membrana e a morfologia celular foram avaliados em microscopia de luz. A motilidade progressiva com ACP-117c declinou após duas horas de refrigeração, mas não diferiu entre a recuperação a fresco e após refrigeração por quatro horas. Vigor e integridade funcional da membrana celular foram significativamente superiores no grupo A4h em comparação ao A0h. O vigor espermático em T2h e T4h reduziu significativamente em comparação com T0h. T0h foi significativamente superior ao A0h quanto aos parâmetros de vigor e integridade funcional da membrana espermática, entretanto, após quatro horas de refrigeração, o ACP-117c apresentou um maior percentual de células vivas. Os espermatozoides epididimários de felinos domésticos conseguem manter a qualidade necessária para serem utilizados em programas de reprodução artificial após serem refrigerados e recuperados por meio da técnica de flutuação modificada, e o diluidor ACP-117c pode ser utilizado com sucesso para recuperação de células espermáticas refrigeradas de gatos por até quatro horas.

ABSTRACT We aimed to compare fresh sperm and sperm cooled to 4ºC that had been recovered from the epididymides of cats using powdered coconut water (ACP-117c) and Tris extenders. Sixty epididymides were divided into 6 groups: 10 fresh epididymides were recovered using Tris (T0h); 10 were kept at 4°C/2h and recovered using Tris (T2h); 10 were kept at 4°C/4h and recovered using Tris (T4h); 10 fresh were recovered using ACP-117c (A0h); 10 were kept at 4°C/2h and recovered using ACP-117c (A2h), and 10 were kept at 4°C/4h and recovered using ACP-117c (A4h). The testis-epididymis complexes (TEC) control were not cooled. The others were cooled at 4°C for 2 or 4h. The epididymis was separated and the sperm was recovered by the modified flotation method. Sperm kinetic parameters were evaluated by a computer-system analysis, and vigor, viability, concentration, membrane function and morphology of the sperm were assessed under a light microscope. The progressive motility with ACP-117c declined after 2h of cooling, but did not differ between fresh and 4h. The vigor and membrane function were higher in A4h than A0h. The vigor at T2h and T4h were decreased compared to T0h. T0h was higher than A0h for vigor and sperm membrane function. However, after 4h of cooling, ACP-117c maintained a higher percentage of living cells. Feline epididymal sperm quality can be maintained to the degree necessary for artificial breeding programs following cooling and ACP-117c may be successfully used to recover cat sperm that have been cooled for up to 4h.

Em Barbalha, Ceará, foram realizados levantamentos de casos de cisticercose suína, teníase e neurocisticercose humana causadas por Taenia solium, e realizou-se uma pesquisa quanto aos sistemas de criação de suínos na região. De 85 suínos abatidos em abatedouro local 4,7% apresentavam cisticercose, a maioria dos cisticercos localizava-se na língua e coração. Entre 2001 e 2004, das 302 criações de suínos denunciadas à vigilância sanitária, 96,6% eram chiqueiros. A teníase, entre 1998 e 2003, correspondeu a 1,1% das verminoses diagnosticadas pela Secretária de Saúde Municipal. Entre 2001 e 2003, os casos de neurocisticercose humana corresponderam a 5% das tomografias de crânio requisitadas nos hospitais da região.

In Barbalha, municipal district of Ceará state, an assessment of cases of porcine cysticercosis, taeniasis and human neurocysticercosis caused by the Taenia solium was performed in order to evaluate the situation of these diseases. It was also carried out a research about the types of swine farms registered in the area. Considering the 85 swine slaughtered at the slaughterhouse of Barbalha, 4.7% presented cysticercosis. Most cysticerci were located in the tongue and in the heart. Between 2001 and 2004, from 302 swine farms denounced to the Sanitary Surveillance, 9.6% were pigsties. Taeniasis, between 1998 and 2003, corresponded to 1.1% of the helminthes diagnosed by the Municipal Health Office. From 2001 to 2003, the cases of human neurocysticercosis corresponded to 5% of the skull tomographies requested in the hospitals of the area.

The aim of this study was to estimate the correlation between scrotal girth and spermatic concentration in German Sheepherd dogs. Thirteen German Sheepherd dogs were used and 44 semen samples were obtained by digital manipulation. The ejaculate was separated in its three fractions. The sperm rich fraction was kept for evaluation and determination of spermatic concentration by spectrofotometry. The parameters were expressed as mean and standard deviation. Spearman correlation test was used to estimate the correlation between spermatic concentration and scrotal girth. The mean spermatic concentration was 568.45±314.91x10(6) sptz/ml and the mean scrotal girth was17.6±1.6 cm and the correlation was r = 0.10. It can be conclude that scrotal girth can not be an appropriate measurement as indicative of spermatic concentration in German Sheepherd dogs.
