Infestação por piolhos Felicola subrostratus em felino domiciliado no município de Parnaíba, Piauí / Infestation by Felicola subrostratus in a feline domiciled in the municipality of Parnaíba, Piauí / Infestación de piojos Felicola subrostratus en felino domiciliado en el municipio de Parnaíba, Piauí

O piolho da espécie Felicola subrostratus é um inseto mastigador responsável por causar a pediculose em felinos e, apesar de ser cosmopolita, tem sua ocorrência pouco descrita na rotina clínica. A transmissão ocorre através do contato direto entre os animais ou por fômites contaminados. Os gatos parasitados podem ser assintomáticos quando em baixa parasitemia, porém em altas infestações podem apresentar prurido, alopecia, dermatites e possibilitar a ocorrência de infecções secundárias. O objetivo deste trabalho foi relatar a infestação por piolhos da espécie Felicola subrostratus em um felino domiciliado no município de Parnaíba, Piauí. O animal era um macho castrado, de dois anos de idade, sem raça definida (SRD), que foi atendido em uma clínica veterinária da cidade, apresentando como queixa principal uma dermatite por lambedura no membro posterior direito, além de prurido, alopecia, apatia, diminuição de apetite e perda de peso. No exame físico, observou-se a dermatite no membro, sendo realizado raspado cutâneo e coleta de pelos da região, verificando a presença de ectoparasitos. Os insetos foram colocados em recipientes com álcool 70ºGL e enviados ao Laboratório de Parasitologia da Universidade Federal do Piauí, que por meio da morfologia revelou ser piolhos da espécie Felicola subrostratus, confirmando o diagnóstico primário de pediculose felina, sendo essencial um diagnóstico precoce para direcionar a um tratamento adequado.(AU)

The lice from the Felicola subrostratus species is a chewing insect responsible for causing pediculosis in felines and, despite being cosmopolitan, its occurrence has been little described in the clinical routine. Transmission occurs through direct contact between animals or through contaminated fomites. The parasitized cats can be asymptomatic when in low parasitemia, but in high infestations, they can present pruritus, alopecia, dermatitis and allow the occurrence of secondary infections. The purpose of this study was to report the infestation by lice of the Felicola subrostratus species in a feline domiciled in the municipality of Parnaíba, in the state of Piauí, Brazil. The animal was a neutered male, two years old, of mixed breed, which was treated at a veterinary clinic in the city, presenting as main complaint a lick dermatitis on the right hind limb, in addition to pruritus, alopecia, apathy, decreased appetite and weight loss. On physical examination, dermatitis was observed on the limb. Skin scraping was performed and fur was collected from the region, verifying the presence of ectoparasites. The insects were placed in recipients with 70ºGL alcohol and sent to the Parasitology Laboratory at the Federal University of Piauí, which through morphology revealed to be lice of the Felicola subrostratus species, confirming the primary diagnosis of feline pediculosis, being essential an early diagnosis to guide the appropriate treatment.(AU)

El piojo de la especie Felicola subrostratus es un insecto masticador responsable de causar pediculosis en felinos y, a pesar de ser cosmopolita, su ocurrencia ha sido poco descrita en la rutina clínica. La transmisión ocurre a través del contacto directo entre animales o por fómites contaminados. Los gatos parasitados pueden ser asintomáticos cuando están en baja parasitemía, pero en altas infestaciones pueden presentar prurito, alopecia, dermatitis y permitir la aparición de infecciones secundarias. El objetivo de este trabajo fue relatar la infestación por piojos de la especie Felicola subrostratus en un felino domiciliado en el municipio de Parnaíba, Piauí. El animal era un macho castrado, de dos años de edad, sin raza definida (SRD), que fue atendido en una clínica veterinaria de la ciudad, presentando como principal síntoma una dermatitis por lamido en el miembro posterior derecho, además de prurito, alopecia, apatía. disminución del apetito y pérdida de peso. En el examen físico se observó dermatitis en la extremidad, se realizó raspado de piel y se recolectó cabello de la región, verificando la presencia de ectoparásitos. Los insectos fueron colocados en recipientes con alcohol 70ºGL y enviados al Laboratorio de Parasitología de la Universidad Federal de Piauí, que por morfología reveló ser piojos de la especie Felicola subrostratus, confirmando el diagnóstico primario de pediculosis felina, siendo fundamental un diagnóstico precoz para orientar el tratamiento adecuado.(AU)

Trypanosoma vivax em bovino leiteiro / Trypanosoma vivax in dairy cattle

Background: Trypanosoma vivax is a protozoan that causes reproductive disorders and decreased production in domestic and wild ungulate animals. The bovine are the main hosts of the disease and the transmission occurs by the bite of hematophagous insects, mainly tabanids. Several diagnostic techniques can be used to detect the parasite, both in parasitological form and by serological kits. In Brazil, the disease has been reported in bovines, goats and sheep of some states, with high morbidity and mortality and due to the scarcity of results on the epidemiology of the disease, this work had the objective to report the presence of T. vivax in a female bovine of a dairy herd in Parnaíba county, Piauí.Case: The animal naturally infected by Trypanosoma vivax, was a three-year-old cow from a dairy farm in the Parnaíba county, located in the north of Piauí state. The farm had a herd whith 62.20% of young Girolando breed cows and the breeding system used was semi-confinement, with two mechanical milking per day. At the time of a Veterinarian’s technical visit to the property, it was observed the occurrence of abortions, mastitis, estrus repetitions and cows with hematuria, leading to the suspicion of the bovine leptospirosis occurrence. Blood samples were collected from 78 cows from the herd for hematological, biochemical and serological tests, and 72 (92.30%) were reactive to some Leptospira serovars. All the exams were carried out at the Federal University of Piauí (UFPI). In the group of animals negative for leptospirosis, a female was diagnosed positive for bovine trypanosomiasis, confirming the result in the blood smear. This animal had no clinical signs characteristic of the disease at the time of the evaluation.[...]

Efeito da adição de angiotensina-(1-7) na taxa de estradiol de cabras submetidas a protocolo de sincronização do estro e ovulação / Effect of angiotensin (1-7) on estradiol rate of goats undergoing synchronization protocol of estrus and ovulation

This study evaluated the effect of angiotensin- (1-7) on the estradiol levels of goats submitted to aprotocol of synchronization of estrus and ovulation when applied close to the ovulatory period. The animalswere divided into two experimental groups: Control (n = 10) and Angiotensin- (1-7) (n = 10). All animals weresubmitted to estrus synchronization protocol and on days 12 and 13 the animals received the treatmentsaccording to the experimental groups and blood samples from the external jugular vein were collected every 12hours for estradiol dosing (E2) by the Elisa test. The results were submitted to analysis of variance followed bythe Dunnett's test (P <0.05). No increase in serum estradiol concentration was observed in any of thetreatments. It was concluded that the application of angiotensin- (1-7) during the preovulatory period, with onlytwo applications, was not sufficient to significantly increase estradiol levels.(AU)
