Developmental surface ultrastructure of Macroorchis spinulosus was studied by scanning electron microscopy. One-day-old juvenile fluke was leaf-shaped and bent ventrally. Body surface was covered densely with peg-like spines and with cobblestone-like cytoplasmic processes. Ciliated sensory papillae were concentrated around oral sucker. Several unciliated sensory papillae occurred equidistantly ...

Black Carp (Mylopharyngodon piceus) has invaded the Mississippi River and is a potential threat to native mollusks. During prior diet research, we discovered that fluke Aspidogaster conchicola, mollusk parasite, occurs regularly in gastrointestinal tract of Carp. The remains fish intestines for extended periods after consumed its host. Flukes were found 33% wild examined, numbers ranged from 1 ...

Background: Cysteine proteases of the liver fluke, Fasciola hepatica, participate in catabolism of proteins, migration of the fluke through host tissues and combat host immune system. Objectives: In this study, we evaluated proteolytic activity of F. hepatica recombinant cathepsin L1 (rCL1) against gelatin and collagen as common substrat...

The continuing decline of many natural plant and animal populations emphasizes the importance conservation strategies. Hybridization as a management tool has proven successful in introducing gene flow to small, inbred populations, but can be also associated with health risks. For example, hybridization change susceptibility infection either direction due heterosis (hybrid vigor) outbreeding dep...

Livestock production around the world is impacted by liver fluke (Fasciola spp.) infection resulting in serious economic losses to beef, dairy and sheep industries with significant of about $90 million per annum Australia. Triclabendazole (TCBZ) most effective anthelmintic treatment available control infections; however, widespread emergence TCBZ resistance livestock threatens control. Alternat...

This study reports the early biochemical changes in plasma, comparative host-immune responses and parasite recovery data in Merino sheep during the first 10 weeks of infection with Fasciola gigantica and Fasciola hepatica. One group of sheep were uninfected, four groups of sheep received incremental challenge doses of F. gigantica metacercariae (50, 125, 225 and 400, respectively) and the sixth...

 A cross sectional study was carried out from October 2010 to March 2011 at Andassa Livestock Research Center, North-West Ethiopia. The objective was to determine the prevalence of cattle flukes infection. Faecal samples were collected from a total of 384 cattle, cross breed (n= 39) and Fogera breed (n=345) of all age groups and sex. Sedimentation technique was employed for the recovery of fluk...

Hepatocellular carcinoma can is often associated with hepatitis B infection. With localised tumours, liver resection can result in a cure. This case presents an unusual finding of concurrent hepatitis B and liver fluke infection with hepatocellular carcinoma in a 50 year old man from Thailand. The discussion illustrates difficulties of arriving at a diagnosis and ensuring appropriate surgical m...
