This work was carried out to compare the coproparasitological and necropsy exams for diagnosis of gastrointestinal helminth infection, evaluating the parasitism frequency in stray dogs captured by the Centro de Vigilância Ambiental of the city of Recife, Pernambuco. A total of 96 dogs of both sexes, with variying ages and races, were used. The animals were sacrificed and necropsied for the collection of adult helminthes. In parallel, fecal samples were collected directly from the rectum of the animals and processed using Willis’s technique and spontaneous sedimentation. The results obtained in the necropsy indicated a positivity of 96.8% (93∕96), being 83.3%, 34.4%, 30.2%, 28.1%, 14.6%, 6.3% and 2.1% for Ancylostoma caninum, Dypilidium caninum, Toxocara canis, Trichuris vulpis, Ancylostoma braziliense, Toxascaris leonina and Spirocerca lupi, respectively. Results from the Willis technique, sedimentation and necropsy were only significantly different (p

Este trabalho foi desenvolvido com o objetivo de comparar os exames coproparasitológicos e necroscópico para diagnóstico da infecção por helmintos gastrintestinais, avaliando a freqüência de parasitismo em cães errantes capturados pelo Centro de Vigilância Ambiental da Cidade de Recife – PE. Um total de 96 cães de ambos os sexos, idade e raça variadas foi utilizado. Os animais foram submetidos à eutanásia e necropsiados para coleta de helmintos adultos. Em paralelo foram coletadas amostras de fezes diretamente da ampola retal dos animais e processadas pela técnica de Willis e sedimentação espontânea. Os resultados obtidos na necropsia apontaram positividade de 96,8% (93 ∕ 96), sendo 83,3%, 34,4%, 30,2%, 28,1%, 14,6%, 6,3% e 2,1%, respectivamente para Ancylostoma caninum, Dypilidium caninum, Toxocara canis, Trichuris vulpis, Ancylostoma braziliense, Toxascaris leonina e Spirocerca lupi. Os métodos de Willis, sedimentação e necropsia foram significativamente diferentes entre si (p < 0,05) apenas na detecção de infecção por Ancylostoma spp. Willis e sedimentação não apresentaram diferenças entre si para os demais helmintos gastrintestinais.

The goal of this research was to analyze the ectoparasitic species from domestic cats in João Pessoa city, Paraíba state, Brazil. A total of 432 cats of various breeds and ages, of both genders, were included. All animals were submitted to physical and parasitological examination through skin inspection and an otoscopic exam was realized. Parasites were collected in vials containing 70% alcohol for subsequent mounting and identifi cation according to specific keys. The results showed that 62.7% (271/432) of animals were parasitized by one or more species. The ectoparasitic species observed were Ctenocephalides felis (27.3%), Lynxacarus radovskyi (26.2%), Otodectes cynotis (17.4%), Felicola subrostratus (9.7%), Notoedres cati (2.1%) and Rhipicephalus sanguineus (1.6%). The results showed that ectoparasites are a common and important skin disease in cats, and variables such breed, age, and sex did not show any influence on parasitism.

The apicomplexa protozoa Cryptosporidium infects several mammals, including terrestrial and aquatic species. In the epidemiology of this infection, the ingestion of water and/or food contamined with oocysts comprises the main mechanism of transmission to susceptible animals. Among the Sirenians, the occurrence of this coccidium has been reported in dugongs (Dugong dugon) and Antillean manatee (Trichechus manatus manatus). The present study was conducted with the aim of verifying the occurrence of Cryptosporidium spp. in Amazonian manatee. For this purpose, fecal samples were collected from ten free-ranging Amazonian manatees, two specimens in captivity, and 103 supernatants fecal samples. The samples were processed by the sedimentation method in formol-ether and Kinyoun stain technique for the presence of Cryptosporidium spp.. The positive samples were then submitted to Direct Immunoflorescence Test. The results showed 4.34% (05/115) of positive samples. This is the first report of Cryptosporidium spp. in the Amazonian manatee.

The goal of this research was to verify the occurrence of Cryptosporidium spp. oocysts in the water consumption and supply of pools used by Antillean manatee (Trichechus manatus) in captivity. Six samples were collected from the pool's supply system (at the beach), water used for manatee consumption, mineral water used in the preparation of artificial milk formulas offered to orphan manatee calves, also used in permanent maintenance pools in the visitation area, and water utilized in the rehabilitation area, where calves of all ages were kept. Before the water samples were processed, each sample was submitted to a filtration process. The diagnosis of the parasite was obtained by Kinyoun technique and the positive samples were submitted to the Direct Immunoflorescence Test. The results showed the presence of Cryptosporidium spp. oocysts in 66.67% (4/6) of the samples from the water supply system and pool, with eight to 56 oocysts per liter. There was evidence that the water used in the maintenance of the Antillean manatees could be an important medium for hydric transmission of Cryptosporidium spp. and that it may be a predisposing factor to the occurrence of cryptosporidiosis in Antillean manatees in captivity.
