Growth and development of Gnathostoma spinigerum (Nematoda: Gnathostomatidae) larvae in Mesocyclops aspericornis (Cyclopoida: Cyclopidae)

Molecular phylogenetic confirmation of Gnathostoma spinigerum Owen, 1836 (Nematoda: Gnathostomatidae) in Laos and Thailand.

We report the molecular-phylogenetic identification of larvae of the nematode genus Gnathostoma Owen, 1836 collected from a snake, Ptyas koros Schlegel, in Laos and adult worms from the stomach of a dog in Thailand. DNA was extracted and amplified targeting the partial cox1 gene and the ITS-2 region of ribosomal DNA. Phylogenetic analyses indicated that all five advanced thirdstage larvae and s...

Intraocular Gnathostoma spinigerum: a case report

Live intraocular nematode is a rare occurrence that is mostly reported in South East Asian countries. Herewith we report such a case from Nayagarh district of Odisha. A 28 year old female presented with swelling, redness, lacrimation, pain & diminished vision of left eye since 2 1/2 years. Slit lamp examination revealed a worm piercing iris muscle. The worm was removed by paracentesis of anteri...

Ultrastructural effects of albendazole on the body wall of Gnathostoma spinigerum third stage larvae.

This study investigated the effects of albendazole (ABZ) on the ultrastructure of Gnathostoma spinigerum advanced third-stage larvae. Two groups of experimentally infected mice received 60 or 90 mg/kg ABZ orally once a day for 21 consecutive days. Both groups had damage to the body walls of the worms, especially to the non-contractile part of the muscular layer. The severity of the damage was d...

Positivity and Intensity of Gnathostoma spinigerum Infective Larvae in Farmed and Wild-Caught Swamp Eels in Thailand

From July 2008 to June 2009, livers of the swamp eels (Monopterus alba) were investigated for advanced third-stage larvae (AL3) of Gnathostoma spinigerum. Results revealed that 10.2% (106/1,037) and 20.4% (78/383) of farmed eels from Aranyaprathet District, Sa Kaeo Province and those of wild-caught eels obtained from a market in Min Buri District of Bangkok, Thailand were infected, respectively...
