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...
متن کاملPrevalence and intensity of third stage Gnathostoma spinigerum larvae in swamp eels sold in three large markets in Bangkok, Thailand.
Gnathostoma spinigerum is a common human tissue parasite in Thailand. The swamp eel is the major intermediate or paratenic host for this parasite. The high prevalence of the infective third stage larvae (L3) of this parasite in the rainy season has been noted in previous studies. During June 1999 (rainy season), we performed a cross-sectional survey of the prevalence and the intensity of G. spi...
متن کاملGnathostoma infective stage larvae in swamp eels (Fluta alba) at a metropolitan market in Bangkok, Thailand.
A total of 1,788 livers from swamp eels (Fluta alba), purchased at a market in Bangkok, Thailand, from April to July 2002, were studied for the prevalence and intensity of Gnasthostoma third stage larvae (L3s). Of all livers, 466 were infected with Gnasthostoma L3s (infection rate = 26%). The larvae recovered averaged 0.43 +/- 0.51 larvae/liver. All larvae were identified as Gnasthostoma spinig...
متن کاملGnathostoma spinigerum in Live Asian Swamp Eels (Monopterus spp.) from Food Markets and Wild Populations, United States
In Southeast Asia, swamp eels (Synbranchidae: Monopterus spp.) are a common source of human gnathostomiasis, a foodborne zoonosis caused by advanced third-stage larvae (AL3) of Gnathostoma spp. nematodes. Live Asian swamp eels are imported to US ethnic food markets, and wild populations exist in several states. To determine whether these eels are infected, we examined 47 eels from markets and 6...
متن کاملGnathostoma infection in fish caught for local consumption in Nakhon Nayok Province, Thailand. II. Deasonal variation in swamp eels.
From August 2000 to August 2001, 1844 swamp eels (Monopterus albus) were purchased from several local markets in Nakhon Nayok Province, Thailand, and examined for the presence of Gnathostoma advanced third-stage larvae. The overall prevalence was 30.1% and the mean number of larvae/eel (infection intensity) was 10.0. The highest infection rate (44.1%) was found in August 2000 and the lowest (10...
