The Sensitivity of Various Bacteria to Chemotherapeutic Agents

Serum, Urine and Tissue Levels of Chloramphenicol in the Horse

“…coli, Salmonella spp., Proteus spp., and perhaps Shigella equuili. A Gram-positive organism, C. equi, was found moderately sensitive to both chloramphenicol and streptomycin, but resistant to penicillin (Rahman 1957). Of the organisms listed, Bnct.…”

Rhodococcus equiinfection in foals: the science of ‘rattles’

“…The classification of Corynebacterium into the order Actinomycetales, which includes the Mycobacterium and Nocardia genera, highlighted the taxonomic proximity of C. equi with pathogens in these related genera. Acid-fast staining properties, intrinsic resistance to penicillin, intracellular pathogenesis, soil saprophytic nature and lipid-rich cell wall composition coupled with the lack of reliable and consistent biochemical test results among isolates called C. equi showed this species to be taxonomically 'lost' among the Corynebacterium, Nocardia and Mycobacterium genera (Jensen 1934;Magnusson 1938;Rahman 1957;Minnikin et al 1978;Barton and Hughes 1984;Zink et al 1987;Barton et al 1989;Sutcliff 1997). The 'rhodochrous' taxon was created in the 1960s to classify these Actinomycetales taxonomic misfits (Gordon 1966).…”

PNEUMONIA ASSOCIATED WITH BORDETELLA BRONCHISEPTICA IN CAPTIVE KOALAS

“…Pneumonia is regarded as a major disease of the koala (Dickens 1975;Arundel et al 1977;Wood 1978); but well defined pneumonia in koalas has been reported in only 4 instances. Cram-positive diphtheroid bacilli similar to Corynebacterium equi were isolated from mucopurulent nasal discharges of 3 koalas from Queensland and from the lungs of 1 other with macroscopic evidence of pneumonia (Rahman 1957;Francis 1963). Backhouse and Bolliger (1961) demonstrated a similar diphtheroid organism in lesions of a purulent pleuropneumonia of a koala from the Sydney region.…”
