Abstract

Zbog učestalog pojavljivanja deformacija kralježnice u različitih uzrasta slobodno živuće populacije glavoča travaša iz Karinskog mora, rengenografski i patomorfološki opisani su utvrđeni deformiteti. Ustanovljena je učestalost njihovog pojavljivanja i utvrđene su histološke promjene u aksijalnom mišićju uzorkovanom u području deformiteta. U istraživanom uzorku glavoča travaša deformacije kralježnice utvrđene su u 11,2% primjeraka, te učestalije u manjih riba. Rengenografski na standardnim projekcijama i makroskopski na preparatima utvrđena su različita povijanja kralježnice (lordoza, skolioza i kifoza) koja se pojavljuju samostalno ili u međusobnim kombinacijama, te brojne promjene na tijelima kralježaka. Histološki nalaz u aksijalnom mišićju uključuje fibrozu intersticija i atrofiju mišićnih vlakana te nametnika roda Kudoa. To je ujedno i prvi nalaz ovog nametnika u glavoča travaša. Za pretpostaviti je da opisane deformacije kralježnice u glavoča travaša nastaju u ranom stadiju razvoja kao prilagodba organizma patološkim promjenama u aksijalnom mišićju, odnosno kao posljedica dugotrajne pojačane mišićne aktivnosti zbog nepravilnog savijanja tijela tijekom plivanja.

Abstract (english)

Because of an increased incidence of spinal deformities in different age classes in natural populations of the grass goby in the Karin Sea, these skeletal changes were examined using radiology and pathomorphology analysis. In addition, histological analysis of the axial muscle was carried to determine the association of the spinal deformity with changes in the axial muscle. Spinal deformities were determined in 11.2% of total grass gobies examined, and were more frequent in smaller fish. Various spinal deformities (lordosis, scoliosis and kyphosis) and numerous changes in the vertebral bodies and associated spine were observed on standard X-ray projections and macroscopically on preparations. Histological examination revealed: interstitial fibrosis, muscle atrophy and parasites of the genus Kudoa. This is also the first finding of this parasite in the grass goby. It is reasonable to assume that the observed changes in the grass goby occur at an early age as a result of adaptation to pathological changes in axial muscle i.e. improper body bending during swimming or prolonged increased workload.
