the experiment was carried out in a factorial arrangement with the base of randomized complete block design in three repetitions. the first factor consisted of 11 bed for eating worm and the second factor is the different seasons (spring and autumn) respectively. traits was including number of capsules (coconut), the number of adult worms, the number of immature worms, live worms masses (mg), m...

Background The French heart worm Angiostrongylus vasorum is a parasitic nematode of the pulmonary arteries and heart of canines often with severe and in some cases fatal outcome. The diagnosis is based on detection and species identification of larvae in faeces which can be problematic in Veterinary praxis especially in cases with low excreting animals. A reliable technique is thus needed for c...

Ocular involvement with Gnathostoma spinigerum occurs years after the initial infection that is acquired by ingestion of poorly cooked, pickled seafood or water contaminated with third stage larvae. Here we report a case of gnathostomiasis of the left eye of a 32-year-old lady hailing from Meghalaya, India. Her vision had deteriorated to hand movement. Slit lamp examination revealed a live, act...

Strongyloides stercoralis is a free living tropical and semitropical soil nematode which its larva penetrates skin. It can complete its life cycle in human body and causes autoinfection. Most patients have no frank symptoms. But respiratory, gastrointestinal and skin manifestation may occur. We report a 76 year old man admitted to emergency room with muscle weakness, dyspnea, nausea, v...

In April 2009, a wild maned wolf, Chrysocyon brachyurus, was captured in an area of cerrado in Brasília, DF, Brazil, with screw worm maggots in external wounds. Fifty larvae were bred in the laboratory and eight adults of Cochliomyia hominivorax (Coquerel) emerged 10 days after pupation. This is the first report of a myiasis by C. hominivorax in a free-living maned wolf in Brazil.

history of epigastric pain and fever. Physical examination revealed marked epigastric tenderness. Laboratory values were: white blood cell count 22000/μL; serum amylase 1461 U/L; lipase 1531 U/L. Computer tomography (CT) scan showed pancreatic swelling with a long, linear filling defect in the pancreatic duct, which was dilated, andmild dilatation of the common bile duct (●" Fig. 1). Endoscopic...

Teladorsagia circumcincta is the most economically important gastrointestinal (abomasal) nematode parasite of sheep in cool temperate regions, to which sheep show genetically-varying resistance to infection. Lambs, from parents with genetic variation for resistance, were trickle infected with L3 larvae over 12 weeks. 45 lambs were identified with a range of susceptibilities as assessed by: adul...

Group A streptococcus is a strict human pathogen that can cause a wide range of diseases, such as tonsillitis, impetigo, necrotizing fasciitis, toxic shock, and acute rheumatic fever. Modeling human diseases in animals is complicated, and rapid, simple, and cost-effective in vivo models of GAS infection are clearly lacking. Recently, the use of non-mammalian models to model human disease is sta...

The effects of tannins on adult populations of Haemonchus contortus, Trichostrongylus colubriformis and Teladorsagia circumcincta in goats are characterised mainly by a decrease in egg excretion without any significant changes in worm number. In contrast, the impact of tannins on T. colubriformis or T. circumcincta third-stage larvae (L3) is associated with a significant reduction in worm estab...
