چکیده
conclusions this study indicated a high percentage of cysts bacterial infections in two provinces of iran. the common isolated bacteria were e. coli and klebsiella. the isolated bacteria degenerated the protoscoleces during short-time incubation, in vitro. results infected cysts were found in 74% of animals in hamedan (46% were calcified and the bacteria was isolated from 52%) and 62% in borujerd. the isolated bacteria in the infected cysts were as follows: escherichia coli, e. blattae, klebsiella pnoumoniae, proteus mirabilis, enterobacter aerogenes, coagulase-positive and coagulase-negative staphylococci, pseudomonas aeruginosa and edwardsiella tarda. the protoscoleces incubated with the isolated bacteria totally degenerated, but 55% of the protoscoleces in the control groups were intact and viable even after one week. objectives the aim of this study was to determine the bacterial infection rate of livestock hydatid cysts in hamedan, iran, and test the isolated bacteria effects on viable protoscoleces, in vitro. materials and methods a total of 5709 slaughtered livestock were inspected to detect the presence of hydatid cysts. the hydatid fluid of all cysts was cultured separately to isolate and identify the bacteria. the effect of isolated bacteria was tested on viable protoscoleces in culture tubes, in vitro. the culture tubes were observed and examined under a light microscope every two hours for 24 hours, and then, after 36 and 48 hours. background the protoscoleces of fertile hydatid cysts are considered as major risks in surgery and producing secondary cysts if rupture the cyst during operation and, cause infecting the dogs with adult worm if eaten by this animal. bacterial infection of the hydatid fluid can lead to sterilization of the cyst.

Introduction: To date, surgery has been the treatment of choice for hydatid cyst, with regard to danger of leakage of hydatid cyst contents into viscera and production of secondary cysts, after spread of protoscolices. Different scolicidal agents get injected into cyst for preventing the secondary cyst production, which may cause different side effects in host, especially in the surrounding tis...

BACKGROUND Surgery is the preferred treatment for hydatid cyst (cystic echinococcosis, CE). At present, various scolicidal agents have been used for inactivation of protoscoleces during surgery, but they are associated with adverse side effects. The aim of the present study was to evaluate the scolicidal effects of amphotricin B, Silver nano particles, Foeniculum vulgare Mill, essential oil and...
