(2009-05) BARBOSA NETO, José Diomedes; DUARTE, Marcos Dutra; OLIVEIRA, Carlos Magno Chaves; REIS, Alessandra dos Santos Belo; PEIXOTO, Tiago da Cunha; PEIXOTO, Paulo Fernando de Vargas; BRITO, Marilene de Farias
Squamous cell carcinoma in goats of two farms in the State of Pará is described. Prevalence, correlation with the pigmentation of the perineal area and macro and microscopic characteristics of the lesions were studied. The tumors on the perineum were of varied development degrees, diameters and forms. On one farm, in the county of Viseu, from a total of 347 goats, 20 presented the neoplasia (5.8%). On the second farm, in the county of Garrafão do Norte, three cases of squamous cell carcinoma in a herd of 400 goats (0.75%) were observed. The tumor was only observed in animals in which the perineal area was despigmented. The high incidence of this tumor appears to be due to lack of pigmentation at the períneo and the high and short tail of the goats, that exposes the area to intense ultraviolet radiation in the tropics.

Encefalomielite equina Leste na Ilha de Marajó, Pará
(Universidade Federal do Pará, 2012-02-29) CAMPOS, Karinny Ferreira; BARBOSA NETO, José Diomedes; http://lattes.cnpq.br/1516707357889557
Nine cases of equine encephalomyelitis were studied in the Marajó Island, State of Pará, Brazil. The animals had difficulty in maintaining a station, walk in a circle, marked depression, eyelids closed, tongue paralysis, muscle tremors, bruxism, anorexia and dehydration. Some had their ear and eyelid reflexes diminished, decreased tongue tone and tachycardia. Position of self-hearing was observed frequently. The animals were often found leaning on tree trunks and fences to keep themselves on station. At necropsy, they showed hemorrhage of the meninges and spinal cord, and some animals also showed adhesion of the meninges. Histologically there was diffuse encephalitis affecting mainly the gray matter, with meningitis and choroiditis. It was observed the presence of perivascular cuffs consisting of mononuclear inflammatory cells. In two animals it was possible to identificate the Eastern equine encephalitis virus by semi-nested reverse transcription polymerase chain reaction (semi-nested RT-PCR).

Prevalência de alterações clínicas e histopatológicas do sistema genital de búfalas (Bubalus bubalis) no Estado do Amapá
(Universidade Federal do Pará, 2007) MOURÃO, Fábio Rodrigo Paixão; RIBEIRO, Haroldo Francisco Lobato; http://lattes.cnpq.br/1614582293203770
Objecting to find out the prevalence of infertility diseases, 895 buffalo cows were submitted to clinical examination with main emphasis on the gynecological aspects and tuberculosis and brucellosis tests, located in Cutias do Araguari country, Amapá State, and analyzed 1000 genitals slaughtered buffalo cows. The prevalence of tuberculosis and brucellosis on clinical analysis were 9,33 and 9,11% respectively. On 895 clinical examined buffalos cows, 299 (33,41%) were pregnant, 188 (62,88%) on the right horn and 111 (37,12%) on left horn. On the buffalo cows group with some alteration, were discovered the following disorders: a) abnormal ovaries: non-functional ovaries, 75 (8,37%); follicular cysts, 6 (0,67%); b) oviduct abnormalities cases: slight adhesions, 24 (2,9%); severe adhesions, 22 (2,46%); hydrosalpinge, 8 (0,9%); c) uterine and cervical abnormalities cases: slight chronic endometrititis, 5 (0,56%); moderate chronic endometritis, 7 (0,78%); irregular cervix, 14 (2,9%); d) Vaginal and vulvar abnormalities cases: lacerated vulva, 9 (1,1%); totalizing 172 (19,21%) buffalo cows with some abnormalities. On the slaughtered buffalo cows were evidenced 661 (66,10%) of pregnancy buffalo cows, that 86 (8,6%) with some reproductive disorder and 339 (33,90%) not pregnancy buffalo cows with 74 (7,4%) with some reproductive disorder. In 661 pregnancy, 412 (62,3%) were in right horn and 249 (37,7%) on left horn. The reproductive abnormalities found were: a) ovarian abnormalities cases: non-functional ovaries, 16 (1,6%); para-ovarian cysts, 5 (0,5%), epithelial inclusion cysts, 8 (0,8%); follicular cysts, 1 (0,1%); b) oviductal abnormalities cases: hydrosalpinge, 18 (1,8%); tubo-ovarian cysts, 5 (0,5%); slight adhesions, 70 (7,0%); severe adhesions 21 (2,1%); c) uterine and cervical abnormalities: entometritis, 9 (0,9%); perimetritis, 3 (0,3%); adenomiosis, 1 (0,1%); segmental aplasia of uterus, 1 (0,1%); twining, 1 (0,1%); irregular cervix, 1 (0,1%). The major percentage of fetus were found on final third of gestation with 236 (35,65%) cases. Several are the problems that can affect the fertility of buffaloes cows and we need to identify it to solve the problems of productivity.

Surto de encefalomielite equina Leste na Ilha de Marajó, Pará

Nine cases of equine encephalomyelitis on Marajó Island, state of Pará, Brazil, were studied. The affected horses had difficulty to stand, walked in circles, with marked depression, closed eyelids, tongue paralysis, muscle tremors, bruxism, anorexia and dehydration. Some had their ear and eyelid reflexes diminished, decreased tongue tone and tachycardia; laid down frequently they kept their head on the chest. Often they were seen resting their head on tree trunks or fences. At necropsy, hemorrhages of the meninges and spinal cord, and in some animals also adhesion of the meninges were found. Histologically there was diffuse encephalitis affecting mainly the gray matter, with meningitis and choroiditis. Presence of perivascular cuffs consisting of mononuclear inflammatory cells was observed. From two horses the Eastern equine encephalitis virus was identified by semi-nested reverse transcription polymerase chain reaction (semi-nested RT-PCR).
