E-mail: diomedes@ufpa.br A condition of buffaloes characterized by an increased volume of one of the cheeks was shown to be due to accumulation of the seeds of the palm-tree “mucaja” (Acrocomia aculeata) and of grass, in the oral vestibulum during rumination. This caused compressive atrophy with thinning and medial deviation of the corresponding submaxillary bone and exposition of the roots of molar teeth. The seeds appear to be of good palatability to the buffaloes.

The cheek mucosa of the labial commissure showed slight erosions. During chewing there was loss of small amounts of grass and saliva through the oral cleft. The affected horses were in good nutritional condition. Histopathological studies of tissues obtained by biopsia, revealed a superficial epidermitis. The pastures consisted of Panicum maximum grass (varieties Tanzânia, Mombaça, Tobiatã and Colonião) which was mature, tall, lignified, with leaves of cutting edges. Based on epidemiological, clinical and histopathological data, it was concluded that the lesions were caused by the hard grass, favored by the way horses pull the tall grass and chew it.

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 of ultraviolet radiation in the tropics.

The isolation and biochemical identification of B. mallei was carried out by microbiological and molecular techniques of PCR-fingerprinting and RAPD-PCR. From the eight samples studied, four showed little phenotype variations. In the molecular tests, the samples formed 4 groups of different ribotype profiles and 4 genotype profiles. There was some association of PCR-fingerprinting with RAPD-PCR results. It was concluded that the slight biochemical variations were not associated with different molecular profiles. They also indicated that these differences show heterogeneity associated with the origin of the sample, indicating that the infection was caused by clones of different strains and that the polymorphism of DNA observed could make it

E-mail: mmjulia_vet@yahoo.com.br The aim of this study was to establish an immunological profile by marking and quantification of T and B lymphocytes in Curraleiro breed by immunocytochemistry. A total of 116 cattle was used, males and females of different ages, from two farms situated in the Goiás State, Brazil. The animals were allotted into groups according to age, sex and origin. Blood samples were collected and processed in accordance with immunocytochemistry standard technique using lymphoid markers species-specific, as anti-CD3 (MM1A - BoCD3) and anti-LB (LCTB16A-clone B-B14), for T and B lymphocyte counting, respectively. The data were submitted to descriptive statistics, and to Kruskall Wallis and Mann-Whitney tests. The results showed decreased levels of leukocytes, lymphocytes, T lymphocytes and B lymphocytes along the age advance. Absolute values of leukocytes, lymphocytes and T lymphocytes were higher in males than females. None of the evaluated parameters were affected by differences of the management carried out at the two farms.

E-mail: alschild@terra.com.br This paper describes organophosphate (ORF) poisoning in a herd of water buffaloes (Bubalus bubalis) in southern Brazil, which were treated with a single dose of 12mg/kg body weight of Expertan® pour-on (chlorpyriphos) to control ectoparasites. Clinical signs, observed 7-45 days after exposure, were diarrhea, hypersalivation, ataxia, muscular tremors, weakness of pelvic limbs, paresis and flaccid paralysis and lateral recumbence. Out of 267 buffaloes 61 died. Necropsy of three animals that died 24-72 hours after onset of clinical signs, revealed congestion and serosal hemorrhages scattered along the bowel, emphysema and edema of the lungs. No significant histopathological changes were found. Residues of chlorpyriphos were detected in liver, kidneys and nervous system of the one necropsied buffalo. Despite the absence of histological lesions in the central and peripheral nervous system, the epidemiological, clinical, gross and toxicological findings suggest delayed neurotoxicity induced by organophosphates.

E-mail: duvaldo@ufu.br Eighteen 18 to 24-month-old mixed breed bullocks were submitted to removal of the apical ligament of the penis to induce penile deviation. After 60 days from the surgery the steers were put together with cows in heat. A ventral and right lateral penis deviation leading to incapacity to copulate was observed. The bullocks were then submitted to an autolgous transplant of a cartilage segment from the ear pinna placed on top of the tunica albuginea, replacing the penile ligament apical tha had been removed. The implanted material was well tolerated; histologically with only infiltration few mononuclear cells, polymorpho nucleated cells and giant cells, and fibrosis, which caused strong adherence and provided ability to sustain the free penile extremity. The bullocks that were cows in heat did not show any degree of penile deviation nor any change in sexual behavior. The surgical method described here was shown to be satisfactory as to be indicated for correction of ventral and right lateral penile deviation in bullocks.

The outbreak was observed in a flock of 250 buffaloes, 80 of which were vaccinated intra-muscularly in the croup against rabies. Four buffaloes fell ill 15 to 19 days after vaccination, one died after a clinical course of 2 days, one was submitted to euthanasia in extremis on the 7th day after the onset of symptoms, and two others recovered within 2 weeks after treatment with penicillin for 4 days and anti-tetanic serum. The first symptoms observed were prolapse of the third eyelid, especially when the animal was stimulated, followed by a rigid walk, as difficulty in inflexing the members and lateral recumbence with the members extended, besides very open eyelids, sialorrhea, hyperexcitability, erect ears and slight lockjaw, and food accumulation in the oral cavity. At post-mortem examination was found a focus of yellowish pus in the croup muscles, where the vaccine had been applied. At histopathology no significant alterations in internal organs were observed. Based on the clinical picture, the epidemic data and absence of histological lesions, the diagnosis of tetanus was established. The infection was considered to be due to the use of dirty needles used during vaccination.
