Rhodococcus equi is a facultative intracellular bacterium causing pyogranulomatous pneumonia with abscessation in young foals as well as opportunistic pyogranulomatous infections in humans and some other animals such as ruminants, pigs, cats and dogs. R. equi can also cause abdominal abscesses or septic arthritis with or without pulmonary disease in foals. My laboratory has recently focused on increased resistance to rifampin and macrolides, which are considered as mainstay dual treatment against R. equi infections in foals. In a new study containing necropsied foals with rhodococcosis, we confirmed this trend of increased dual resistance in necropsied foals treated with mainstay dual therapy. In addition, we demonstrated that R. equi isolates with pREerm46 significantly increased MICs for trimethoprim- sulfamethoxazole and doxycycline in addition to macrolides. Despite dual therapy, increased resistance against rifampin and macrolides warrants evaluation of new treatment protocols in foals. Currently we are investigating some other drugs in laboratory conditions against rifampin- and macrolides-resistant R. equi isolates.
