Streptococcus equi subspecies zooepidemicus (S. zooepidemicus) is a Lancefield group C beta-hemolytic streptococcus. S. zooepidemicus is commonly found colonizing the mucous membranes of healthy equids. The specific name „zooepidemicus‟ derives from its wide host range. Mastitis in cattle and goats; pneumonia, septicemia, and wound infections in lambs and dogs; septicemia in chickens and dolphins; and lymphadenitis in guinea pigs are examples of its widely ranging pathogenicity. Infections of humans with S. zooepidemicus are associated with consumption of unpasteurized cow and goat milk products, as well as with close contacts with horses.
In this paper we describe a case of polyarthritis in Alpine kids caused by S. zooepidemicus. Four Alpine kids (one month old) were submitted for necropsy in order to reveal cause of death. After necropsy, altered tissues and milk samples originated from two goats from the same farm were processed with standard bacteriological methods and with polyme...rase chain reaction in order to detect Mycoplasma spp. DNA. From owner, we got informations that kids several days before death developed joint swelling, apathy, inappetence and inability to move. Kids were held together with other goats, sheep and lambs, horses and llamas. There were no clinical signs of illnes in other animals on the farm.
At external examination of carcasses edema of periarticular tissue was seen. Discrete hyperemia and crust were seen on ears around ear tag. Necropsy revealed severe fibrinous polyarthritis in all examined kids. There were no pathomorphological alterations on other organs. Affected were shoulder, knee and hip joint. Sheets of white to yellow fibrin partially or completely cover the articular surfaces. From all joints S. zooepidemicus were isolated while milk samples were negative. No Mycoplasma spp. DNA was detected neither from milk or joints.
Although S. zooepidemicus induces wide range of pathological conditions in different animal species, as far as we know, our report represents the first described case of arthritis in kids caused by this bacteria. In lack of any signs of illness in other animal species on farm, as well as negative pathomorphological findings in other organs and negative bacteriological results from milk samples, source and route of infection for kids remain unclear. We assume that source of bacteria were horses present on farm and that lesions on ears represents the portal of entry of S. zooepidemicus in kids. It would be tempting to speculate that isolated strain is highly adaptable for goat kids and further molecular studies are needed to investigate that hypothesis.
