Pathogens commonly isolated from selected diseases Equine pneumonia/pleuropneumonia -hemolytic Strep. Clostridium Pasteurella E. coli Klebsiella pneumoniae Bacteroides Equine enteric pathogens Salmonella Clostridium difficile Equine neonatal septicemia pathogens Actinobacillus Klebsiella pneumoniae
Equine infectious keratitis Staphylococcus Corynebacterium Bacillus Streptomyces Klebsiella Acinetobacter Fungal isolates are also common: Aspergillus, Fusarium, Penicillium, Candida Canine respiratory pathogens (often multiple pathogens) Staphylococcus Mycoplasma Pasteurella Klebsiella Bordetella bronchiseptica Also Mycoplasma spp. Clostridium perfringens Bacterioides Prevotella Porphyromonas Canine otitis externa isolates Corynebacterium spp. Proteus spp. Cats have similar profiles, but also have Pasteurella multocida. Yeast is commonly isolated with bacteria.
Canine otitis media/interna isolates α-hemolytic β-hemolytic Corynebacterium Enterococcus spp. Proteus spp. Superficial canine pyoderma (often only one pathogen) Proteus spp.* spp.* * *Some of numerous other organisms that may be cultured from deep pyoderma. Canine urinary tract infection isolates (often only one pathogen) Canine mastitis isolates Staphylococcus aureus -hemolytic Streptococci -hemolytic Streptococci Klebsiella pneumoniae Proteus mirabilis Staphylococcus Mastitis is uncommon in queens.
Canine prostatitis isolates are the same as UTI s Staphylococcus aureus -hemolytic Streptococci -hemolytic Streptococci Klebsiella pneumoniae Proteus mirabilis Canine and feline CNS isolates Staph epidermidis Staph albus Actinomyces Nocardia Pasteurella multocida Peptostreptococcus Eubacterium Bacteroides Canine osteomyelitis isolates Actinomyces Nocardia Pasteurella Proteus Klebsiella Peptostreptococcus Clostridium Bacteroides
Canine diskospondylitis isolates Actinomyces Brucella canis Canine and feline pyothorax isolates canis Nocardia (dogs most common aerobe) Klebsiella pneumonia Pasteurella (cats most common aerobe) Actinomyces Peptostreptococcus (dogs most common anaerobe) Bacterioides (cats most common anaerobe) Porphyromonas Prevotella Canine and feline peritonitis isolates (non-septic also common, eg. bile, urine) faecalis Serratia Clostridium perfringens Bacteroides
Major categories of canine subgingival bacteria (462 isolates) (58%) (42%) (41%) 36% 5% (58%) 21% 37% Major categories of feline subgingival bacteria (326 isolates) (56%) (44%) (34%) 29% 5% (66%) 27% 39% Feline respiratory pathogens spp. Pasteurella multocida. Bordetella bronchiseptica Klebsiella spp. Proteus spp. Moraxella spp. Mycoplasma Feline keratitis/conjunctivitis Chlamydia psittaci Mycoplasma felis Bovine infectious pododermatitis isolates?? necrophorum Dichelobacter nodosus
Bovine CNS Listeria monocytogenes Histophilus somni E. coli (septic calves) Bovine respiratory disease isolates Arcanobacterium pyogenes and Strep.spp in chronic cases only Mannheimia haemolytica Pasteurella multocida Histophilus somni Mycoplasma bovis also commonly isolated, significance is debated but now considered at least a primary component. However, successful treatment is often achieved with antimicrobials not necessarily containing Mycoplasma in the spectrum. Bovine mastitis Also Mycoplasma Staphylococcus aureus agalactiae Strep uberis Strep dysgalactiae Klebsiella Bovine enteric disease isolates Salmonella spp. Clostridium perfringens
Porcine respiratory disease Also Mycoplasma hyopneumoniae Actinobacillus pleuropneumoniae Actinobacillus suis Haemophilus parasuis Pasteurella multocida Bordetella bronchiseptica Salmonella cholerasuis Porcine enteric disease isolates Salmonella Swine dysentery Serpulina hyodysenteriae Proliferative ileitis Lawsonia intracellularis Porcine CNS disease isolates Strep suis
