Metacercariae recovered from fresh-water fishes in the vicinity of Qualkyobia Governorate, Egypt

A total of 410 Tilapia zillii, 70 Clarias gariepinus, 30 Bagrus bajad and 15 Chlrysichthys auratus fishes were collected from different water bodies in Qualyobia Governorate. Microscopic examination of samples showed infection in muscles and head region [gills and branchial cavity] with encysted metacercariae in 91.7% of T. zillii, 82.85% of Cl. gariepinus, 70% of B. bajad and 86.66% of Ch. auratus. The highest distribution of metacercarial infection among the T. zillii was in the muscles of posterior third and tail followed by the middle third, anterior third and head region [gills and branchial cavity] while the highest distribution of metacercarial infection among Cl. gariepinus was in the middle third muscles followed by the posterior third, anterior third and lastly in the head region. The highest metacercarial infection among B. bajad and Ch. auratus fish was in the posterior third muscles and branchial cavity respectively. The taxonomic morphology of the encysted metacercariae and the excysted ones was given

prevalence of entamoeba gingivalis and trichomonas tenax in periodontal disease

Two hundred patients [100 males and 100 females] having either marginal periodontitis or gingivitis were examined for detection of E. gingivalis and T. tenax. E. gingivalis was more prevalent among patients with periodontitis particularly females, while T. tenax was not discovered entirely in both patients and control groups
