| description | Canine otitis externa is a common reason for a visit to the vet. Predisposing
factors often complicate treatment and may result in a chronic disease
progression. All otic preparation for topical use in Fass Vet contain antibiotics,
corticosteroids and a fungicide. Sixty cerumen samples from dogs with external
otitis, sent to the Department of Bacteriology at SVA, were categorised according
to their profile of isolated microorganisms. Staphylococcus intermedius alone or
together with Malassezia pachydermatis were the most common organisms found.
Fifteen percent of the samples contained M. pachydermatis only. M.
pachydermatis and Pseudomonas aeruginosa in combination was also fairly
common. Combinations of S. intermedius, P. aeruginosa and M. pachydermatis
comprised about 80 % of the material.
Antimicrobial susceptibility of S. intermedius and P. aeruginosa was determined
to antibiotics used in drugs licensed for veterinary otic preparations. Resistance to
some of those antibiotics was seen as well as to some other antibiotics. A
relatively high number of penicillin-resistant isolates of S. intermedius was found
(81.5%). The antimicrobial susceptibility pattern in this study was similar to that
of other studies on S. intermedius isolates from dogs with chronic otitis and
pyodermias. The majority of bacterial isolates in this study were most likely
sampled from dogs with chronic otitis. A larger study would be required to
2
investigate a possible connection between antibiotic resistance in bacteria that can
cause chronic otitis and antibiotic treatment of the dog for other diseases. |

Otitis externa hos hund är en vanlig orsak till veterinärbesök. Sjukdomen har ofta ett antal predisponerande faktorer vilka kan medföra komplikationer och leda till ett kroniskt förlopp. Ett av de vanligaste behandlingsalternativen för extern otit innefattar topikala otit preparat innehållandes antibiotika, kortison och fungicid. Sextio prov för bakterieodling på öronsekret från hundar med otit, skickade till Avd. för Bakteriologi, SVA. Provsvaren sammanställdes för att få en uppfattning om mikroorganismfloran med särskild hänsyn till förekomsten av potentiellt patogena mikroorganismer. Staphylococcus intermedius var den vanligaste isolerade bakterien involverad i otit, ibland i kombination med Malassezia pachydermatis (jästsvamp). I 15 % av proverna fanns endast M. pachydermatis, därefter var en kombination av M. pachydermatis och Pseudomonas aeruginosa vanligast. Kombinationer med S. intermedius, P. aeruginosa och M. pachydermatis utgjorde ca 80 % av inskickat material. Det andra syftet med studien var att undersöka de påvisade bakteriernas resistens mot de olika antibiotika som ingår i otitpreparaten i Fass Vet. Resistensbestämningarna för de två vanligaste bakterierna, S. intermedius och P. aeruginosa sammanställdes. Resistens påvisades mot några av de antibiotika som ingår i otitpreparaten men också mot sådana antibiotika som normalt inte används för otitbehandling. Andelen penicillinresistenta S. intermedius var 81,5 %, vilket var högt jämfört med andra studier. För S. intermedius kunde förekomst av resistens i denna studie jämföras med resistens hos hundar med kroniska hudlidanden (otiter, pyodermier) i andra studier. Resultaten skulle delvis kunna förklaras med att de flesta prov i denna studie sannolikt kommer från hundar med återkommande otiter. Större studier skulle behövas för att klargöra ett potentiellt samband mellan antibiotikabehandling av andra sjukdomar än otit och resistens hos bakterier som orsakar otit. 2005-02-21 Other NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/11534/1/mieziewska_k_171003.pdf Mieziewska, Kristina, 2005.
