Abstrak desportesius sp. merupakan nematoda parasit yang menyerang burung dari ordo ciconiiformes. desportesius sp. umumnya ditemukan menginfeksi proventrikulus burung air. tujuan dari penelitian ini adalah untuk mengetahui lesi histopatologi proventrikulus kadaver burung kuntul kerbau (bubulcus ibis) yang positif terinfeksi desportesius sp. pada kasus lapang. penelitian ini menggunakan sampel berupa 6 proventrikulus kadaver burung kuntul kerbau yang positif terinfeksi desportesius sp. proventrikulus diproses menjadi sediaan histopatologi dan diwarnai menggunakan pewarnaan hematoksilin dan eosin. sediaan histopatologi diamati dan dianalisis secara deskriptif dengan mendeskripsikan perubahan histopatologi yang terjadi pada sampel proventrikulus. hasil pemeriksaan menunjukkan adanya perubahan histopatologi proventrikulus yang mencakup hiperemi, udema, hemoragi, nekrosis, infiltrasi sel radang, deskuamasi, ulserasi, potongan cacing desportesius sp., dan eosinofilik pseudocoelomic fluid. berdasarkan hasil pengamatan, seluruh sampel proventrikulus kadaver burung kuntul kerbau mengalami proventrikulitis hemoragik et nekrotikan.

ABSTRACT Desportesius sp. is a parasitic nematode that attacks birds of the order Ciconiiformes. Desportesius sp. It is commonly found to infect the proventriculus of waterbirds. The purpose of this study is to determine the histopathological lesions of the proventriculus of cattle egret (Bubulcus ibis) cadavers that were positively infected by Desportesius sp. in field case. This study used samples in the form of 6 proventriculus of cattle egret cadavers that were positive for Desportesius sp. Proventriculus is processed into histopathological preparations and stained using hematoxicillin and eosine staining. Histopathological preparations were observed and analyzed descriptively by describing the histopathological changes that occurred in the proventriculus sample. The examination results indicate histopathological changes in the proventriculus, which include hyperemia, edema, hemorrhage, necrotic, inflammatory cell infiltration, desquamation, ulceration, sections of Desportesius sp., and eosinophilic pseudocoelomic fluid. Based on the observations, all proventriculus samples from cattle egret cadavers exhibited proventriculitis haemorrhagic et necroticans.
