The use of artificial insemination (AI) with heterospermic doses (Het) in swine may benefit reproductive performance by diluting individual differences among boars. However, such practice may also mask the true reproductive potential of some individuals, which can be measured through homospermic AI (Hom). This study evaluated boar reproductive performance after AI with Hom and Het doses. Ejaculates were collected from 4 boars and combined in 10 treatments: 4 with Hom doses (boars A, B, C and D) and 6 with Het doses (AB, AC, AD, BC, BD and CD) all having concentration of 3 billion spermatozoa in 80 mL doses with equal contribution of each boar. The in vitro analyses of sperm quality were: sperm membrane, DNA and acrossome integrity; mitochondrial functionality; and in vitro oocyte penetration. Thereafter, 511 females having parities from 1 to 6 were inseminated and the farrowing rate (FR) and total litter size (TB) were recorded. Both FR (Hom = 90.5% and Hem = 89.9%), and TB (Hom = 12.4 ?? 0.4 and Het = 12.7 ?? 0.7) did not differ (P>0,05). Some differences were observed among treatments, such as: the maximum FR (98.0%) for treatment AC and the minimum (87.0) for boar B; and a difference of two piglets among the maximum (for the CD treatment) and the minimum observed value (for the AC treatment). The only difference observed on the in vitro evaluations (P<0.05)...

The feline immunodeficiency virus belongs to the Retroviridae family, Lentivirus gennus and presents molecular structure and pathogenicity similar to the human immunodeficiency virus (HIV), therefore it is not transmissible to humans, being susceptible only the domestic and feral cats. FIV is classified in five phylogenetically different subtypes from A to E spread worldwide, apart from recombinant strains among the subtypes. Recently, two new subtypes were described, the subtype F identified in the United States and Portugal, and the subtype U-NZenv in New Zealand. Considering that the retroviruses have the ability to integrate the cell genome, under double stranded DNA form, it is possible to detect the provirus in infected leucocytes through the polymerase chain reaction (PCR) technique. The present report investigated the occurrence of the feline immunodeficiency virus infection between 2010 and 2011 in domestic cats submitted to medical treatment at the Hospital of Veterinary Clinics of the Federal University of Pelotas and private clinics from Pelotas, RS. Blood samples of seventy animals, healthy or sick, were collected and subjected to the nested-PCR technique. The tested cats were classified in two groups taking into account their clinical condition: the group 1 represented 28 FIV suspect cats with lymphadenomegaly...

Salmonelosis is a term to designate patologies caused by the Salmonella genus, which has an extensive dissemination in the poultry environment and a large interconnection with wild birds, which act as reservoirs. Salmonella sp. is representative of the Enterobacteria s family, being usually associated with infections on aviary, and human food poisoning. It can, mainly in wild birds, present as asymptomatic form, which give to these animals the status of carrier and diffuser in the environment. The present research had the purpose to detect wild bird carriers of the agent, also by inoculation of the found strain in vivo, realize the retro isolation, so researching the effects caused on poultry production and evaluating its impact over the aviculture. The biological material that had been collected of the wild birds was derived of cloacal swabs, totalizing 121 samples of eleven different groups, which were processed by isolation. Only one from the 121 samples was positive, isolated in a Magellanic penguin (Spheniscus magellanicus), then was inoculated in chicks (Gallus gallus) with one day of age, which were challenged and watched for 12 days. In total 21 chicks were used as biological model, distributed in 3 groups, one positive control (inoculated with a known sample of Salmonella)...

The peripartum in dairy cows (three weeks before and three weeks after calving) is characterized by large changes in physiological demands in the animal where management practices, particularly nutrition, strongly influences the incidence of peripartum disorders and subsequent milk production. Most of the studies in that period in dairy cows are focused on confined systems where milk production is high. Therefore, the aim of this study was to assess metabolic markers associated with the occurrence of clinical and subclinical mastitis and insulin resistance in dairy cows in semi extensive system. Our study was divided into two major experiments with the following hypothesis: 1) medium milk production primiparous cows in semi extensive system have predictive metabolic markers of clinical and subclinical mastitis in the prepartum, 2) medium milk production pluriparous dairy cows with low rate of glucose metabolism during the prepartum, which is an indicative of insulin resistance, have higher minerals excretion in the postpartum period. In experiment 1, blood concentrations of NEFA in the prepartum period were higher, in contrast, phosphorus and glucose were lower (P <0.05) in animals with clinical mastitis postpartum. In experiment 2...

Leptospirosis is a disease caused by pathogenic spirochetes of the Leptospira genus. This zoonosis of worldwide distribution causes veterinarian and public health issues, especially in underdeveloped and developing countries with tropical and subtropical climates. In veterinary medicine, leptospirosis is important both as a clinical problem, causing illness in domestic animals, and an economic problem, causing productive and reproductive losses in commercial herds. Vaccination of these animals is applied, however protection conferred by these conventional vaccines is limited, and the carrier status is not always avoided. Recombinant outer membrane proteins seem to be the most promising antigens to replace the traditional bacterins (whole cell inactivated preparations), but thus far none of the tested proteins have turned satisfactory results. The goal of this study was to assess recombinant antigens and vaccine preparations, regarding their capability of producing protective immunity in hamsters, against lethal leptospirosis. Moreover, heterologous protection was sought, and assessed. The prevalence anti-Leptospira antibodies in stray dogs from the city of Pelotas was assessed using serogroups Icterohaemorrhagie and Canicola antigens. Several experiments were conducted to assess the protective potential of previously described leptospiral proteins. Twenty seven proteins were used to immunize hamsters which were then challenged with virulent Leptospira. Furthermore...

Salmonella is one of the main causative agents of foodborne diseases, and chicken-based products play a prominent role in this context, serving as vehicles to the microorganism. The present study aimed to provide data on the Salmonella spread in the poultry chain, check the occurrence of Salmonella and its different serotypes isolated from chicken stool, chicken products and human stool, as well as to verify the similarity between DNA profiles of Samonella isolated. Literature on the occurrence of Salmonella in the poultry chain was reviewed; parallel to it, a project in which 600 samples (200 chicken meat, 200 chicken stool and 200 human stool samples) were analyzed for Salmonella presence was developed. DNA profiles of isolated strains were obtained by PFGE and REP-PCR. The microorganism was isolated from 16 samples, 8 (8/200 4%) from chicken products, 4 of which (4/200 2%) from chicken stool and 4 (4/200 2%) from human stool. Salmonella serotype Schwarzengrund was found to prevail both in chicken meat and chicken stool, followed by serotype Mbandaka, whereas serotype Panama prevailed in humans. Strains with indistinguishable genotypes were found to be present both in chicken stool and chicken products, suggesting that the chicken contamination on the farm remained in the processed product. In humans...

Brazil has one of the largest commercial heard of the world and it is a great beef exporter. Meanwhile, for the consolidation of Brazilian exportation of meat in natura and its derivatives it is necessary that the products have food safety. Among the microorganisms used as indicators of food security, Salmonella has a special attention because it causes severe diseases to animals and humans. This study was developed with the objective to isolate Salmonella during the cattle slaughter in a state inspection slaughterhouse located in the city of Pelotas, Rio Grande do Sul. A hundred and fifty samples were collected from three different points of slaughter: leather of the animal after bleeding (P1), the carcass after evisceration (P2) and cecum contents (P3). The isolates were tested for their antimicrobial susceptibility in vitro using amoxicillin, ampicillin and ciprofloxacin. As results, two (1,33%) strains were isolated from bovines and classified as Salmonella. No strain was isolated from buffalos. The two isolates were susceptible to amoxicillin and ciprofloxacin. Besides the investigation of the presence of Salmonella in the cattle flowchart, a review about Salmonella pathogenicity islands (SPI) was performed. According to the results...

The present study has the objective to evaluate the epidemiologic factors related to respiratory diseases in thoroughbred foals placed in four stud farms around the city of Bag??/RS region, Brazil. Apart from the collection of data linked to breeding management practices, the evaluations consisted of the diary clinical control and complementary examinations for diagnosis using secretions collected from the respiratory tract of the foals affected with respiratory diseases. Among the 349 monitored foals until their 180 days of life, the incidence of 9,5% (33) of respiratory cases with 0,57% (2) of mortality was recorded. The concentration of cases was higher in months of summer, the 120 and 180 days old foals were more susceptible. The occurrence of the diseases was influenced by the breeding system and management practices that increased the environmental contamination potential, and also by the contact among the foals. No clinic case was related to the equine influenza virus (EIV) and to the equine herpesvirus (EHV) pathogens. Among the isolated pathogens, the highest frequency was for Streptococcus equi (57%), followed by Rhodococcus equi (17%) and this one was responsible for 50% of lethality. The obtained results suggest that connected factors to the management in the breeding of thoroughbred equine are going to contribute decisively for the manifestation of the respiratory disease and alert for the high morbidity caused by the equine adenitis and the high lethality related to Rhodococcus equi pathogens.; O presente estudo teve por objetivo avaliar fatores epidemiol??gicos associados com doen??as respirat??rias em potros Puro Sangue Ingl??s (PSI) alojados em 4 propriedades na regi??o da cidade de Bag??-RS...

Penguins are seabirds that spends about 75% of their life on the sea, and when they are found weak, this birds are sent to rehabilitation centers. Although, their extensive adaptations to sealife can become limiting issues to their life in captive, occurring, often, bumblefoot, or pododermatitis, cases: a foot disease that can evolve to septicemia and death. The Centro de Recupera????o de Animais Marinhos (CRAM Marine Animals Recovery Center) is the place that, in Brazil, recieve more penguins to rahabilitation. Given the CRAM s importance in the national matter in penguin rehabilitation, the research objective was to evaluate the bumlefoot epidemiology in the birds kept captive in CRAM, trying to minimize the injuries that accompany the syndrome during rehabilitation period. Were observed 129 penguins in CRAM, where the syndrome incidence were 75%, presenting, the abrasive surface as main predisposing factor for development. The research presented the bumblefoot usually as a bilateral disease and with a progressive course. Every foot pads where qualified according the injury level to clinic evaluation, showing, by creating a method of biometric measurement of edema between each lesion score. The fungal microorganisms were related to the penguin s foot pad s transitory microbiota...

Sporotrichosis has been receiving attention in any world in the several areas of the health as an important fungal disease. So, this work aimed: (i) to study cases of sporotrichosis diagnosed in the south region of Rio Grande do Sul in a period of ten years, (ii) to study the morphological and pathogenicity characteristics of S. schenckii isolates, (iii) to determine the sensitivity of S. schenckii isolates to the commercial disinfectants. Sporotrichosis cases were analysed as for geographical distribution, it clinical forms of the disease, presence of the fungus in different anatomical sites and tecidual inflammatory response. The 42 S. schenckii isolates originating from clinical cases, environment isolates and reference strains used in the phenotypic study were evaluated as for macromorphology in Sabouraud agar added of chloramphenicol, potato agar and ??gar lactrimel, incubated 25??C and 35??C for 21 days. The micromorphology was analyzed in potato agar to 25??C whereas the termotholerance was evaluated in ??gar Sabouraud added of 1% yeast extract, incubated 41??C for seven days. Ultraestructural study of nine clinical isolates and two reference strains of S. schenckii were carried by transmission electron microscopy. Susceptibility of 12 S. schenckii isolates to disinfectants was performed by the techniques of broth microdilution...

The mammary neoplasms are tumors that most affect bitches and represent a problem of great impact in veterinary medicine. Malignant tumors are associated to high mortality due to tumor recurrence or metastasis. This study aimed to evaluate prognostic factors of low cost and easy to perform diagnostic routines, capable of predicting the biological behavior of these tumors. The samples were collected from 114 bitches submitted surgical excision of mammary neoplasms from 2004 to 2008. The patients followed over a period of two years after therapy. This study did not include animals that had distant metastasis at diagnosis. Information regarding to ovariohysterectomy concurrent with the removal of the neoplasm, recurrences, time of observation of the tumor, age and weight of the animals were obtained through standard protocols for submission of tumors. The samples were fixed in 10% formalin, measured, the margins of interest identified with India ink and were systematically cleaved allowing full evaluation of the specimen. Histological sections were stained with hematoxylin-eosin and evaluated under light microscopy. The dependent variables evaluated were: histologic type, histologic grading, histological stage, invasion to adjacent tissues...

A retrospective study of clostridial diagnosed in ruminants from 1978-2008 in southern Rio Grande do Sul, was conducted in the influence area of the Regional Diagnostic Laboratory of the Federal University of Pelotas. Out of 5.446 bovine specimens sent by practitioners or from necropsies performed 91 (1,67%) were diagnosed as clostridiosis. Of those, 30 (0.55%) were diagnosed as by black leg, 15 (0.27%) as bacillary hemoglobinuria, 9 (0.16%) as botulism, 9 (0.16%) as malignant edema, and 28 (0.51%) as tetanus. Out of 860 sheep specimens 49 (5.69%) were bacterial diseases and 14 (28,57%) of those were diagnosed as clostridiosis, being 10 (1.16%) cases of tetanus, 3 (0.34%) of malignant edema, and 1 (0.11%) %) of enterotoxemia. It was concluded that some clostridiosis cause important losses in livestock in Rio Grande do Sul, mainly black leg. The vaccination of young stock against black leg is recommended in the whole state. Vaccination against botulism is recommended in areas of native pastures where phosphorus deficieny occurs, and vaccination against bacillary hemoglobinuria is recommended in low lands where fasciolosis is enzootic. In cattle, tetanus may occur as outbreaks with significant economic losses, recommending also the vaccination of animals. In sheep clostridioses are less important being tetanus the more frequent. Good hygienic practices...
