The study evaluated the anti-Toxplasma gondii antibodies occurrence in dairy goats in São Paulo State, and also verified likely associations with age, sex, presence of cats, occurrence of reproductive problems, and potential risks to public health. Serum was obtained from 923 animals of both sex, over three months of age from 17 properties in different cities. For the diagnosis, the indirect immunofluorescence reaction (RIFIe”16) and a questionnaire about health to collect epidemiological information and the reproductive cycle of every goat were used. Among all properties, 15 foci of T. gondii were diagnosed with seropositivity ranging from 2.70% to 81.25%. Neither association between the frequency of seropositivity and the sex of animals nor occurrence of reproduction failure of goats was identified. There was positive influence of anti-T. gondii antibody rate due to the older age of the animals and the presence of cats in pens. The risk of transmitting T. gondii to the public health must be considered, once in some properties where the positive serology was verified natural, products such as milk and/or meat are commercialized. Results were discussed at 5% level of significance.

The report describes a winter dysentery outbreak that affected 10 dairy cows from a ranch located in the county of Viamão, Rio Grande do Sul. The most significant clinical sign was profuse and watery diarrhea, which ranged from a greenish to a brownish coloration and from occasional blood streaks with mucus to a bloody diarrhea. Most cases persisted for 5 days and also included depression, drastic decrease in milk production and in food consumption. Only one of the affected animals died. The necropsy revealed pale mucosa and sanguineous content with high quantity of blood clots, particularly within the spiral colon, and petechiae on the colonic mucosa. Histopathological lesions were predominant in the spiral colon, and consisted of a high number of dilated crypts without epithelium or with the replacement of a pavement epithelium with occasional immature cuboidal cells, which sometimes showed enlarged nucleus and proeminent nucleolus. Some crypts were filled with epithelial desquamation and polymorphnuclear cells. Bovine coronavirus (8F2) monoclonal antibody was used for immunohistochemistry on sections of the spiral colon that showed positive reactions in the cytoplasm of the infected crypt epithelium, sloughed necrotic cells, and within macrophages in the lamina propria of both.

The present study was carried out in 11 dairy herds in four municipal districts of the rural area of the State of Pernambuco, Brazil. Out of 984 quarter milk (246 cows), 10 (1.0%) were positive for clinical mastitis, 562 (57.1%) for subclinical mastitis and 412 (41.9%) were negative. A total of 81 Staphylococcus spp. isolates were obtained from milk samples from the cows diagnosed with subclinical mastitis. From these, 53 (65.0%) were S. aureus, 16 (20.0%) coagulase-positive staphylococci (CPS) and 12 (15.0%) coagulase-negative staphylococci (CNS). The isolates were further investigated for the presence of toxin genes by multiplex and uniplex PCR. The main gene observed was seg followed by seh, sei and sej. The distribution of these observed genes among the isolates obtained from different areas showed a regional pattern for the SEs. The presence of toxin genes in the strains isolated from bovine milk demonstrates a potential problem for public health.

To determine plant poisonings occurring on Marajo Island, state of Pará, northern Brazil, 7 farms were visited. All farms had native pastures with low forage availability severely infected by Ipomoea asarifolia. In 5 farms poisoning in sheep by the plant was reported. The disease occurs mainly during the dry period and lambs are more frequently affected than adult sheep. Sheep with clinical signs were observed in 2 farms. In 4 establishments farmers reported the occurrence of I. asarifolia poisoning in cattle. In one farm affected cattle were observed during two visits, one during the dry season and another at the start of the raining season. Deaths are observed mainly in calves. In both species the poisoning occurs every year with variable morbidity and low mortality. One bovine and one sheep with severe clinical signs were euthanized and post-mortem examination was performed. No gross or histologic significant lesions were observed. In all farms buffaloes were raised together with cattle and sheep, and in 3 farms goats were also raised. None of the farmers reported the intoxication in these species.

For standardization of the rabies immunohistochemistry technique, five samples of central nervous system (CNS) of cattle naturally infected with rabies virus were examined. One polyclonal antibody and two monoclonal antibodies were used. The following reagents were evaluated for antigen retrieval: XIV protease, proteinase K and citrate buffer (pH 6.0) boiling at 100°C during 15 minutes in bain-marie. Detection of rabic antigen was possible with the three antibodies tested. The polyclonal antibody was superior to the monoclonal antibodies, demonstrating good results with the three antigen retrieval protocols. The highest intensity staining was obtained with the citrate buffer and heat. The immunohistochemistry technique demonstrated the presence of viral antigens in the cytoplasm of neurons, in form of aggregates or with round or oval shape. The antigens were found as single or multiples inclusion bodies in the neurons. Immunohistochemistry is a fast method that can be used in routine procedures in cases where rabies is suspected, especially when the brain is submitted to the laboratory as formalin-fixed fragments or when samples could not be immediately shipped. The technique is also useful for retrospective studies.

A study of the skin diseases in sheep and goats in the semiarid of the states of Paraíba, Pernambuco and Rio Grande do Norte, Northeastern Brazil was performed. From January 2000 to November 2006, 656 cases in goats and 324 in sheep were presented to the Veterinary Hospital of the Federal University of Campina Grande in Patos, Paraíba. Additionally mailed in biopsy or necropsy skin samples from 31 goats and 45 sheep were studied histologically. Skin diseases were diagnosed in 35 goats (5.33% of all cases in this species) and 45 sheep (13.88% of the cases in this species). The most frequent skin disease was myiasis (10 cases in goats and 7 in sheep), followed by contagious echtyma (8 cases in goats and 2 in sheep), squamous cell carcinoma (4 cases in goats and 5 in sheep), dermatophylosis (8 cases in sheep), and allergic dermatitis (1 case in goats and 1 in sheep). Two cases of pythiosis in sheep, two cases of epidermolysis bullosa in goats, one case of poisoning by Brachiaria brizantha (photosensitization) and another by Leucaena leucocephala (alopecia) in sheep, and one case of papillomatosis, one of pemphigus foliaceous, one of protothecosis and one of rhabdomyosarcoma in goats were also diagnosed. In 4 cases in sheep and 19 in goats the etiologic diagnosis was not obtained. With the information of the occurrence and epidemiology of the skin diseases is possible to determine efficient control measures.

Laparoscopy is not widely used as a tool to perform assisted reproduction techniques in South American cervids; thus, scarce information in literature is available regarding its effects and appropriate anesthetic protocols to perform it. This study evaluated the effect of laparoscopy on heart rate (HR), respiration rate (RR), saturation of oxyhemoglobin (SpO2) and rectal temperature (RT) of six female brown brocket deer (Mazama gouazoubira) anesthetized with ketamine (5mg/kg), xylazine (0.3mg/kg), midazolam (0.5mg/kg) combination i.v. and isoflurane. Twelve laparoscopies were performed and each animal was used twice with a 40-day interval. After anesthetized, the animals were placed in dorsal recumbency to perform laparoscopy procedure using abdominal CO2 insufflations (14.2 ± 2.39mmHg; M ± SE). The main events of the laparoscopy procedure were divided into three periods: animal without (P1) and with abdominal insufflation (P2) and abdominal insufflation with the hips raised at 45° (P3). As a control, the animals were anesthetized again 40 days after the last laparoscopy, and were maintained in a dorsal recumbency for the same average duration of the previous anesthesia and no laparoscopy procedure was conducted. The period of anesthesia for the controls was also divided into P1, P2, and P3 considering the average duration of these periods in previous laparoscopies performed. Data were analyzed through the (ANOVA) variance analysis followed by Tukey test and values at P<0.05 were considered significant. No significant differences were observed in the parameters evaluated at P1, P2 and P3 between the animals submitted to laparoscopy and control. However, the RR mean between P1 (38.8 ± 4.42) and P3 (32.7 ± 4.81); and the RT mean between the P1 (38.2°C ± 0.17), P2 (37.6°C ± 0.19) and P3 (37.0°C ± 0.21) varied significantly, independent of the laparoscopy. These data indicated that laparoscopy didn’t cause any significant alterations in the cardiorespiratory parameters evaluated, even though the anesthetic protocol used can cause a reduction in the RT contributing to development of hypothermia during anesthesia.

This paper reports the anesthetic effects of the combination of tiletamine HCl, zolazepam HCl, and xylazine HCl in tigrinas, Leopardus tigrinus Schreber, 1775 (Fam. Felidae), submitted to semen collection by electroejaculation. Three different protocols and the individual anesthetic doses were calculated by interspecific allometric scaling, based on the usual recommendations for a 10.0 kg domestic dog: On Protocol 1 (n=10) the basis for calculation was 5.0mg/kg for tiletamine + zolazepam and 0.5mg/kg for xylazine; on Protocol 2 (n=12) 5.0mg/kg for tiletamine + zolazepam and 0.75mg/kg for xylazine; and on Protocol 3 (n=11) 5.0mg/kg for tiletamine + zolazepam and 1.0mg/kg for xylazine. The tigrinas were anesthetized on three different occasions with a minimum interval of 30 days. During 120 minutes after the drug administration cardiac and respiratory frequencies, rectal temperature, limb myorelaxation and sensitivity to deep pain were monitored. Latency period, anesthetic period, and contamination of the semen with urine were also monitored. From a total of 32 collections, 10 samples (31.2%) and 18 aliquots (0.07%) were contaminated and rejected, but this episodes were not detrimental for semen analysis and processing. A discrete increase in rectal temperature during electroejaculation caused by muscle contraction, followed by temperature decrease, was observed. Cardiac and respiratory frequency varied during the experiment, but remained within physiological standards for the species. The three tested protocols showed to be safe and effective to produce analgesia and anesthesia in L. tigrinus during semen collection by electroejaculation.

This paper reports an outbreak of poisoning by Palicourea aeneofusca in cattle, in the municipality of Jacaraú, and another by Mascagnia rigida in the municipality of Sapé. Both outbreaks occurred in the Zona da Mata of Paraíba, where there are no previous reports of poisoning by toxic plants causing sudden death associated to exercise. The toxicity of both plants was tested in rabbits. The lethal dose was of 3g per kg body weight (g/kg) for fresh P. aeneofusca and 10g/kg for fresh Mascagnia rigida. On the farm where the poisoning by P. aeneofusca was observed, M. rigida also was found. The farmer reported that this plant also caused sudden death previously. M. rigida collected on that farm and given dried to rabbits caused death at the dose of 10gkg. The poisoning by P. aeneofusca in cattle had been previously reported in the Zona da Mata and Agreste of Pernambuco and east of Bahia. There are also numerous farmers’ reports about the occurrence of the poisoning in the Zona da Mata of Alagoas, suggesting that it occurs in the whole coastal region, from Bahia to Paraíba. M. rigida is the most important toxic plant for cattle in the Brazilian semiarid. The results of this paper demonstrate that this plant poisoning also occurs in the tropical wet climate of the Zona da Mata.
