Abstract
The occurrence of members of the Pasteurellaceae and Neisseriaceae families was studied in dogs and cats. A total of 110 nasal and pharyngeal swab samples from 47 dogs and 8 cats were collected. Most of the strains were identified by 16S rDNA sequencing, except Frederiksenia canicola and Pasteurella multocida where species-specific polymerase chain reactions were applied. The most frequently isolated species was F. canicola, which occurred only in dogs, mainly in the pharyngeal cavity. The second commonest bacterium, P. multocida was found in both types of samples and in both hosts. Other species from the family Pasteurellaceae, such as Haemophilus haemoglobinophilus, Pasteurella canis and P. dagmatis, were detected only in dogs. All isolated species belonging to the family Neisseriaceae, mainly representing Neisseria weaveri, were found only in the pharyngeal cavity. Neisseria weaveri and N. zoodegmatis could be detected in both hosts. Neisseria dumasiana and N. canis were isolated from dogs, while N. shayeganii only from a cat. For phylogenetic analysis, rpoB gene sequencing was performed, where the strains were on monophyletic branches and clearly separated from each other. In this study, recently described species such as F. canicola, N. shayeganii and N. dumasiana were detected that had never been isolated in Hungary before.
Highlights
Representatives of multiple species belonging to the Pasteurellaceae and Neisseriaceae families have been found on the mucosal surfaces of the upper respiratory tract of vertebrates as opportunistic pathogens (Kuhnert et al, 2012; Hurst, 2018)
Our knowledge is constantly expanding by new bacterial species such as Frederiksenia canicola (Korczak et al, 2014), Neisseria shayeganii, N. wadsworthii (Wolfgang et al, 2011) and N. dumasiana (Wroblewski et al, 2017)
Recent studies have proved that Tasmanian devils (Sarcophilus harrisii) and other marsupial species may be infected by F. canicola (Brix et al, 2015; Hansen et al, 2017)
