Larvas de helmintos no solo de praças públicas de Caxias, Maranhão, Brasil / Helminth larvae in the soil of public squares in Caxias, Maranhão, Brazil / Larvas de helmintos en el suelo de plazas públicas en Caxias, Maranhão, Brasil

Solos de praças públicas são comumente contaminados por helmintos devido ao fácil acesso de cães e gatos infectados. Esses animais ao defecarem podem liberar ovos desses parasitos e, em condições ambientais favoráveis, tornam-se ovos embrionados ou larvas infectantes. O objetivo deste trabalho foi investigar a existência de larvas de helmintos no solo de duas praças públicas do município de Caxias, Maranhão, Brasil, durante a estação chuvosa e seca na região. A pesquisa foi realizada em março de 2018, considerado período chuvoso, e em outubro do mesmo ano, período seco, sendo que foram coletadas trinta amostras de areia, quinze de cada praça, nos dois períodos do ano. O material foi coletado e levado para o Laboratório de Parasitologia do Departamento de Parasitologia e Microbiologia da Universidade Federal do Piauí para análise. Na estação chuvosa, das quinze amostras analisadas na praça A, cinco foram positivas para larvas de ancilostomídeos e das quinze na praça B, três estavam contaminadas com os mesmos helmintos. No período seco, na praça A havia apenas uma amostra com essas larvas e na praça B não foram encontrados parasitos. Os resultados revelaram a presença de larvas de helmintos de caráter zoonótico no solo de praças públicas de Caxias, Maranhão, principalmente no período chuvoso, servindo de alerta à população local.(AU)

Soil in public squares is commonly contaminated by helminths due to the easy access of infected dogs and cats. These animals, when defecating, can release helminth eggs and, under favorable environmental conditions, those eggs can become embryonated or infective larvae. The purpose of this work was to investigate the existence of helminth larvae in the soil of two public squares in the city of Caxias, in the state of Maranhão, Brazil, during the rainy and dry seasons in the region. The study was carried out in March 2018, which is considered the rainy season, and in October of the same year, the dry season. A total of thirty sand samples were collected, fifteen from each square, in both periods of the year. The material was collected and taken to the Parasitology Laboratory of the Department of Parasitology and Microbiology of the Federal University of Piauí for analysis. In the rainy season, from the fifteen samples analyzed in square A, five were positive for hookworm larvae; and from the fifteen samples collected from square B, three were contaminated with the same helminths. During the dry period, only one sample from square A presented these larvae while no parasites were found in square B. The results revealed the presence of zoonotic helminth larvae in the soil of public squares in Caxias, Maranhão, mainly in the rainy season, which can be used as a warning sign to the local population.(AU)

Los suelos de las plazas públicas son comúnmente contaminados por helmintos debido al fácil acceso de perros y gatos infectados. Esos animales, al defecar, pueden liberar huevos de esos parásitos y, en condiciones ambientales favorables, convertirse en huevos embrionados o larvas infectantes. El objetivo de este trabajo fue investigar la existencia de larvas de helmintos en el suelo de dos plazas públicas de la ciudad de Caxias, Maranhão, Brasil, durante la estación lluviosa y seca de la región. La investigación se realizó en marzo de 2018, considerada época de lluvias, y en octubre del mismo año, época seca, y se recolectaron treinta muestras de arena, quince de cada plaza, en ambos períodos del año. El material fue recolectado y llevado al Laboratorio de Parasitología del Departamento de Parasitología y Microbiología de la Universidad Federal de Piauí para su análisis. En época de lluvias, de las quince muestras analizadas en la plaza A, cinco resultaron positivas a larvas de anquilostomiasis y de las quince de la plaza B, tres estaban contaminadas con los mismos helmintos. En el período poco lluvioso, en la plaza A solo hubo una muestra con esas larvas y en la plaza B no se encontraron parásitos. Los resultados revelaron la presencia de larvas de helmintos zoonóticos en el suelo de las plazas públicas de Caxias, Maranhão, principalmente en la época de lluvias, sirviendo de alerta a la población local.(AU)

Ovarian pedicle hemostasis techniques in cats.

PURPOSE: To evaluate hemostasis of the ovarian arteriovenous complex (OAVC) in relation to surgical time, practicality and feasibility in three ovariohysterectomy (OH) techniques for queens. METHODS: The experiment was performed on 21 female cats aged between six months and seven years, randomly arranged into three groups in a completely randomized design. Group one was spayed using the conventional three-clamp technique, group two using the OAVC knotting technique, and group three using the ovarian pedicle rotation technique. The student's t-test and Tukey's test were used to compare the mean surgical times. RESULTS: The conventional technique, which uses thread wires, was more laborious and required longer execution time compared to the other two techniques. The OAVC knotting technique was the fastest and had the least blood loss. CONCLUSIONS: The use of techniques that do not use synthetic materials for OAVC hemostasis was proven to be appropriate in castration projects, provided that the surgical team has sufficient training.
