| Popis: | Salmonelozu konja prouzroče različiti serovari Gram-negativne bakterije Salmonella enterica subsp. enterica. Klinička slika salmoneloze ponajprije ovisi o tome radi li se o infekciji serovarom prilagođenim konjima (Salmonella Abortusequi) ili drugim serovarima salmonela. Vrsno specifični serovar S. Abortusequi prouzroči pobačaje u kasnijem stadiju graviditeta ili, nešto rjeđe, orhitis te septikemiju, osteomijelitis i artritis u ždrjebadi. Drugi, vrsno nespecifični serovari, prouzroče crijevne ili sustavne infekcije. Salmonelama se mogu inficirati različite vrste životinja i ljudi, a mnoge vrste životinja, ponajprije ptice i glodavci, česti su rezervoari salmonela koji bakterije izmetom izlučuju u okoliš. Konji se inficiraju ingestijom salmonela iz mnogobrojnih izvora u okolišu, ponajprije vode i hrane kontaminirane izmetom ili lešinama bolesnih životinja i životinja kliconoša. Infekcija salmonelama u konja može biti subklinička ili se očitovati kao blaga febrilna bolest, enterokolitis ili septikemija. Najčešći simptomi bolesti su: proljev, vrućica, količni bolovi i leukopenija. Bolest se dokazuje izdvajanjem salmonela iz izmeta konja, a liječenje i prognoza ovise o kliničkom obliku bolesti. Prevencija salmoneloze otežana je zbog velike proširenosti salmonela u okolišu, no u slučajevima pojave bolesti, širenje na druge konje može se spriječiti izolacijom bolesne životinje i dezinfekcijom kontaminiranog okoliša. Čimbenici koji doprinose izlučivanju salmonela i/ili razvoju kliničkog oblika bolesti u subklinički inficiranih konja (stres, promjena hrane, antimikrobna terapija, kirurški zahvati) često su prisutni u hospitaliziranih životinja te ih zbog toga treba smatrati potencijalnim izvorima infekcije za druge životinje i ljude. Equine salmonellosis is caused by various serovars of the Gram-negative bacteria Salmonella enterica subsp. enterica. Clinical signs of salmonellosis depend on the infective serovar and many factors influencing host susceptibility. The host specific serovar Salmonella abortusequi causes abortion at a later stage of pregnancy or, more rarely, orchitis and septicemia, osteomyelitis and arthritis in foals. Other host nonspecific serovars cause intestinal or systemic infections. Salmonella sp. infects a variety of animals and also humans. Many animal species, predominantly birds and rodents, are often salmonella reservoirs and excrete the bacteria in the environment. Horses become infected by ingesting Salmonella from many sources in the environment, primarily food and water contaminated by bacteria or by the carcasses of infected animals. Salmonella infection in horses may be subclinical or manifest as mild febrile disease, enterocolitis or septicaemia. The most common clinical findings are diarrhoea, fever, colic and leukopenia. The disease is confirmed by isolation of bacteria from the faeces, and the treatment and prognosis depend on the clinical form of the disease. Prevention of equine salmonellosis is hampered by the presence of numerous sources of infection in the environment. However, in the case of illness, the spread to other horses can be prevented by isolation of the infected animal and disinfection of the contaminated environment. Factors contributing to the excretion of Salmonella bacteria and/or the development of clinical form of disease in inapparently infected horses (stress, change in feeding behaviour, antimicrobial therapy, surgical procedures) are often present in hospitalized animals, which should therefore be considered as potential sources of infection for other animals and humans. |
