“…Pouco mais de um terço dos cadáveres suínos conclusivos remetidos para necropsia era proveniente de Santa Maria [213 (38,2%) (Filippsen et al 2001, SEAPA 2012. Esta realidade da Mesorregião Centro-Ocidental do Rio Grande do Sul pode ser comprovada pelo fato de pouco mais de 5% dos animais remetidos para necropsia sejam da espécie suína e as principais doenças diagnosticadas reflitam o modo de criação.…”

“…Do total, as doenças bacterianas perfizeram 59% da causa de morte ou razão para eutanásia dos suínos. As doenças bacterianas geralmente estão ligadas a outros fatores (multifatoriais) como ambiente, manejo e nutrição (Tateyama et al 2000, Filippsen et al 2001, Chang & Stear 2006, Sobestiansky et al 2012a. Levando em consideração o estilo de criação de suínos predominante na região de abrangência do estudo, é esperado que doenças com estas características fossem mais prevalentes.…”

“…O diagnóstico é baseado nos dados epidemiológicos, clínicos e de necropsia. O isolamento da bactéria pode ser feito com caracterização do gene responsável pela produção da toxina e confirma a suspeita (Filippsen et al 2001). O edema é a lesão mais característica e pode ser observado principalmente nas pálpebras, no subcutâneo e na submucosa do estômago, e tende a desaparecer com o tempo após a morte (Barcellos & Sobestiansky 2003, Fairbrother & Gyles 2006.…”

RESUMO.-Visando-se determinar as características e frequência das doenças na população suína na região de abrangência do Laboratório de Patologia Veterinária (LPV) da Universidade Federal de Santa Maria (UFSM), foi realizado um estudo retrospectivo de todos os diagnósticos de necropsias realizadas nesta espécie no período de 1964 a 2011. Foram separados 564 casos com diagnósticos conclusivos. A criação suína na região de abrangência do estudo é predominantemente familiar e as doenças diagnosticadas, refletem esta realidade. As doenças infecciosas e parasitá-rias foram as mais prevalentes [380(68,1%) was carried out in order to determine the characteristics and frequency of diseases in the swine population raised in the region the region covered by the activities of LPV. Five hundred and four cases with conclusive diagnosis were found. The type of pig-raising in the area is mainly a familiar enterprise and the diseases found in this survey reflect this reality Infectious and parasitic diseases were the most prevalent [380(68.1%)], followed, in descending order of frequency, by nutritional and metabolic diseases [64(11.5%)], poisonings and toxi-infections and development disorders [15(2.7%)]. Other disorders due to varying etiologies, especially trauma, were cause of death in just over 11% of the cases. Bacterial diseases were responsible for more than half of the causes of death in pigs of the studied population, pointing to the influence of management, environmental and nutritional regional husbandry. The moist frequent disease diagnosed in pigs in the region in the region covered by the study was edema disease which along with other forms of infection by Escherichia coli was responsible for 23% of deaths. Viral diseases and neoplasm were not major causes of death in pigs in the region studied. Nutritional hepatosis and aflatoxicosis are important diseases in pigs in this region and and there causation are mainly linked to nutritional management.INDEX TERMS: Swine diseases, veterinary pathology, epidemiology, causes of death, retrospective study.

“…In a research performed in Brazil, out of 910 pig sera collected from slaughterhouses in central region of the State of São Paulo, only 2.7% were reactive in the screening test, but did not react to confirmatory tests (2-ME), resulting in no positive samples (Rosa et al 2012). Filippsen et al (2001) also had 0% of positivity for brucellosis in 969 animals from Southwest of Paraná. Braga et al (2013), in the State of Piauí, detected antibodies anti-Brucella spp.…”

“…However, despite the facts, these slaughterhouses do not receive the necessary attention (Rosa et al 2012). Therefore, management and biosecurity are extremely important issues in maintaining a healthy herd (Filippsen et al 2001). Considering the importance of the disease for pork production, this study aimed to determine the occurrence of antibodies anti-Brucella spp in 1940 pig blood sample from intensive pig farming and non-technified pig herds.…”

ABSTRACT.-Ricardo P., Oliveira L.G., Baraldi T.G., Mechler M.L., Almeida H.M.S., Silva G.C.P., Gatto I. The aim of this study was to determine the occurrence of antibodies anti-Brucella in 1,940 swine blood samples. Out of the 1,940 sera samples, 1,594 were from 30 intensive pig farming from seven different states, collected during the slaughtering of animals, and 346 samples from 56 non-technified (subsistence) pig herds from Jaboticabal region, São Paulo State, Brazil. All samples were tested by Buffered Plate Acidified Antigen (BPAA) and considered positive in case of agglutination. If positive, the samples were tested by Complement Fixation Reaction (CFR) as a confirmatory test. Out of the 1,594, two were positive for BPAA but negative for CFR, so the occurrence was 0%. Among the 346 samples, two were positive for BPAA but only one was positive in the confirmatory test, whith a titer of 1:8. Thus, the occurrence was 0.29%, an important result to demonstrate the improvement of the sanitary status of Brazilian non-technified pig herds, despite the low conditions of production.

Summary The aim of this study was to determine the prevalence and to identify the risk factors associated with Leptospira spp. infection in technified pig farms in the state of Alagoas, Brazil. To compose sample for the prevalence study, 342 pigs were used (312 sows and 30 boars) proceeding from seven swine farms distributed in five districts of the state of Alagoas, Brazil. The infection’s serological diagnosis was performed by microscopic agglutination test. The risk factors analysis was performed using research questionnaires consisting of objective questions related to the breeder, the general characteristics of the property, and the productive, reproductive and sanitary management. Prevalence of 16.1% (55/342) of pigs seropositive was obtained. The associated risk factors were not performing quarantine (P = 0.003, OR = 5.43, CI = 1.79–16.41) and the use of artificial insemination (P = 0.023, OR = 3.38, CI = 1.18–9.66). A significant association of sow infection with the increased number of stillborn and mummified foetuses was found, as well as with the increased frequency of oestrus recurrence and the increased weaning‐to‐oestrus interval of seropositive sows. One might state that Leptospira spp. infection is disseminated in technified pig farms in the State of Alagoas, favouring reproductive failures and the impairment of zootechnical performance in these properties. The risk factors identified in this study are facilitators in the infecting agent dissemination and should be adjusted to control the disease in the herds studied.
