BACTERIAL CULTURE OF TRACHEAL ASPIRATE OR LUNG TISSUE OF 76 FOALS PRESENTED WITH CLINICAL SIGNS OF PNEUMONIADepartment of Large Animal Internal MedicineGhent University, BelgiumZoé Neuckermans, Ellen Paulussen, Alexander Dufourni, Laurence Lefère, Gunther van LoonDepartment of Large Animal Internal Medicine, Faculty of Veterinary Medicine, Ghent University, BelgiumINTRODUCTIONContact: zoe.neuckermans@ugent.be• Most common bacterial isolates in foals with pneumonia :- Streptococcus equi subsp. zooepidemicus (Strep-zoo)- Rhodococcus equi (R. equi)• Little is reported about their relative frequency of occurrence.• Aim of this retrospective study : report the results of bacterial culture oftracheobronchial aspirate or lung tissue (necropsy) of foals presentedwith clinical signs of pneumonia.METHODS• Bacterial cultures obtained from foals aged between 0 and 365 dayspresented between January 2009 and December 2018 with clinical signsof pneumonia including depression, fever, cough, nasal discharge anddyspnea at our referral hospital were reviewed.RESULTS Strep-zoo R. equiMean age (days) 129 59Survival to discharge 81.5 % 64.7 %Lung abscesses on ultrasound 37 % 76 %• Highest prevalence of Strep-zoo in our population• Higher survival to discharge for Strep-zoo• Age of the foal and presence of abscesses on ultrasound might be suggestive for the causativepathogen• Proper diagnosis is essential to avoid unnecessary use of critical antibiotics and to better defineprognosisCONCLUSION• In total, 76 foals met the inclusion criteria.• Strep-zoo (35.5%)  and R. equi (24.4%) showed the highest prevalence.• Other isolates included : Actinobacillus spp. (n=5), Pseudomonas spp. (n= 3), E. Coli (n= 2), Klebsiella spp. (n= 1 ), Bordetella spp. (n= 1), Staphylococcus spp. (n= 1), Strep. equi subsp. equi (n=1).• 2 samples were positive for both pathogens and 7 samples were negative.• Comparison of Step-zoo and R. equi is as follows :Strep-zoo R. equi
