Abstract

Objective: The prevalence of resistant bacteria in pet birds, zoo birds and falconry birds is still largely unknown. Therefore, antibiograms of rapidly-growing aerobic bacteria obtained from these birds were retrospectively evaluated. Material and methods: Between 2007 and 2016 a total of 1036 antibiograms were evaluated. The bacteria isolates originated from 811 birds of 20 zoological orders (mostly Psittaciformes [61.8 %] and Passeriformes [14.5 %] and from alive patients or pathological examinations. The birds were primarily kept in Southern Germany. Phenotypic in vitro sensitivity of bacterial isolates to various antibiotics was determined using a standardized agar diffusion test. Results: The most frequently examined bacteria species wereEscherichia coli(n = 386 isolates), Staphylococcus(S.).aureus(n = 150), Enterobacter cloacae(n = 122),Klebsiella pneumoniae(n = 86) and Pseudomonas aeruginosa(n = 64). Resistance to at least one antibiotic agent was detected in 53.1 % of the E. coliisolates, most commonly to doxycycline (50.3 %) and ampicillin (46.1 %), as well as in 95.9 % of Enterococcus faecalisisolates and 78.0 % of Staphylococcus aureusisolates. Multidrug resistance to 3 or more antibiotic groups was frequent inS. aureus(37.3 % of isolates). Resistance rates were higher in isolates from pet birds and captive birds of prey than in isolates from zoo birds.Resistant isolates were more common in Psittaciformes than in Passeriformes. An increasing resistance rate for fluoroquinolones in E. coli(a minimum of 0 % in 2005 and a maximum of 27.3 % in 2011) and decreasing resistance rates for tetracyclines in S. aureus(a maximum of 38.2 % in 2007 and lowest values of 0 % in 2014 and 2015) were observed over the examined period.
