Paratuberculose em ruminantes no Brasil Paratuberculosis in ruminants in Brasil: a review

Abstract

A paratuberculose ou doença de Johne é uma enterite granulomatosa causada por Mycobacterium avium subsp. paratuberculosis (Map) e comumente afeta ruminantes domésticos, no entanto, pode infectar várias espécies de mamíferos. Está presente nos cinco continentes e é considerada endêmica em algumas regiões pela Organização Internacional de Epizootias (OIE). Pertence à lista de enfermidades notificáveis, que compreende as doenças transmissíveis de importância sócio-econômica e/ou em saúde-pública, cujo controle é necessário para o comércio internacional de animais e alimentos de origem animal. A importância da doença de Johne não se restringe somente aos preju��zos econômicos causados à indústria animal, mas também na possível participação do Map na íleocolite granulomatosa que afeta seres humanos, conhecida como doença de Crohn. No Brasil, a paratuberculose já foi descrita em diversas espécies de ruminantes e em vários estados. Embora os relatos naturais da enfermidade sejam pontuais, acredita-se na possibilidade da transmissão interespecífica e na disseminação do agente através da compra e venda de animais infectados. O objetivo deste artigo foi reunir as informações disponíveis referentes aos aspectos epidemiológicos, clínico-patológicos e laboratoriais da paratuberculose em bovinos, bubalinos, caprinos e ovinos no Brasil, e salientar a necessidade de implementação de medidas de controle sanitário da enfermidade no país, o que possibilitaria a melhoria da qualidade e valorização dos produtos de origem animal no mercado internacional.Paratuberculosis also known as Johne's disease, is a granulomatous enteritis caused by Mycobacterium avium subsp. paratuberculosis (MAP), an acid-fast bacillus that preferentially resides within host intestinal macrophages. The condition is most commonly seen in domestic ruminants, however MAP can also infect other mammalian species. Paratuberculosis shows a global distribution and is considered endemic in some regions. The World Organization for Animal Health (OIE, Office International des Epizooties), have classified paratuberculosis as a notificable disease; considered to be of socio-economic and/or public-health importance, the control of which is necessary for the international trade of animal and animal products. The importance of paratuberculosis is related primarily to economic losses in the animal industry and also because of a potential role for this bacterium in the pathogenesis of Crohn´s disease, a debilitating condition affecting the digestive tract of humans. In Brazil, paratuberculosis has been reported in a variety of ruminant species and shows a broad geographic distribution. The reported incidence of natural cases in Brazil has been limited, but it is believed that interespecific transmission of MAP and dissemination of the agent is driven by the commercialization of infected animals. The main objective of this paper was to collate the published epidemiological, clinic-pathological and diagnostic information in relation to paratuberculosis in cattle, buffaloes, goats and sheep in Brazil. Moreover, it served as a platform to emphasize the requirement to implement sanitary policies for control of MAP in the county, which may serve to improve the quality and value of animal products on international markets.
