Abstract

Upala sluznice vanjskog zvukovoda predstavlja izazov u dijagnostici zbog njene složene etiologije. Učestalost i mogući uzročnici upale još su nedovoljno istraženi u slobodnoživućih mačaka. U svrhu ovog istraživanja prikupljeni su obrisci sluznica vanjskih zvukovoda i uzoraka cerumena od 75 uhvaćenih slobodnoživućih mačaka u vremenskom periodu od lipnja do listopada 2018. godine. Inspekcijom su pregledane uške mačaka, izvršen je otoskopski pregled sluznice vanjskog zvukovoda i bubnjića te se procijenio izgled i količina cerumena. Prikupljeni uzorci obrađeni su citološkom i mikološkom pretragom. Otoskopskim pregledom utvrđeno je da se upala sluznice vanjskog zvukovoda klinički očitovala povećanom količinom cerumena u 41,3% mačaka, koji je bio crno smeđe boje u 38,7% odnosno mrvičast u 26,7% mačaka. Obradom podataka u 41,3% mačaka citološkom pretragom utvrđena je upala sluznice vanjskog zvukovoda. Kod mačaka starijih od godinu dana utvrđena je veća učestalost upala u odnosu na mačke mlađe od godinu dana. Najveći broj upala uzrokovale su gljivica Malassezia sp. te gljivica i ušna grinja O. cynotis zajedno. Kokoidne i štapićaste bakterije utvrđene su u 9,5% odnosno 5,4% mačaka. Citološkom pretragom, kod 80% mačaka s kliničkim znakovima, potvrđena je upala sluznice vanjskog zvukovoda. Subkliničke upale utvrđene su u 5,3% mačaka. Nadalje, jedina vrsta iz roda Malassezia koja je uspješno izolirana bila je M. pachydermatis. Upala sluznice vanjskog zvukovoda nije rijetka pojava i prilikom postavljanja dijagnoze potrebno je uzeti u obzir kliničke znakove zajedno s citološkom i mikološkom pretragom kako bi se utvrdio primarni uzrok i pravilno liječila životinja.

Abstract (english)

Otitis externa presents a challenge in diagnostics due to its complex etiology. In street cats prevalence and possible causes are still unexplored. For the purpose of this research, ear swabs and cerumen samples were collected from 75 street cats from June to October 2018. Ear pinna was inspected and otoscopic examination of the external ear canal has been conducted to determine the condition of mucosa, tympanum and quality and quantity of cerumen. Samples were subjected to cytological and mycological examination. Otoscopic examination found that otitis externa was clinically manifested with increased amounts of cerumen in 41.3% of cats, which was dark brown in 38.7% and crumbly in 26.7% of cats. Results of cytological examination have shown the prevalence of otitis externa in 41,3% of cats. Cats older than one year had higher prevalence of otitis externa than cats younger than one year. In most cats, otitis externa was caused by Malassezia spp. and combination of Malassezia spp. and ear mite O. cynotis. Rods and cocci were present in small number of inflammation. Cocci were the only cause of otitis externa in 1,4% of cats. Results of cytological examination have shown the prevalence of otitis externa in 80% of cats with clinical sings of inflammation. Only in 5,3% of cats subclinical inflammation was present. M. pachydermatis was the only species from the genus Malassezia that has been successfully isolated. Otitis externa is not a rare disease and one has to take in consideration clinical signs, cytological and mycological results to determine primary cause of otitis externa and to treat animal properly.
