| Complete genomic sequence of a reovirus isolated from grass carp in China. | A reovirus was isolated from sick grass carp in Guangdong, China in 2009, and tentatively named 'grass carp reovirus Guangdong 108 strain' (GCRV-GD108). This reovirus was propagated in grass carp snout fibroblast cell line PSF with no obvious cytopathic effects. Its genome was 24,703bp in length with a 50% G+C content and 11 dsRNA segments encoding 11 proteins instead of 12 proteins. It has been classified as an Aquareovirus (AQRV). Sequence comparisons showed that it possessed only 7 homologous ... | 2011 | 22044618 |
| [Molecular properties of grass carp reovirus in southern China and establishment of a duplex PCR detection method]. | A strain of grass carp reovirus was isolated from sick grass carp with symptoms of haemorrhage in Guangdong province in 2009. The strain was tentatively named as GCRV-GD108 because it was isolated from grass carp and possessed 11 segments of dsRNA. Complete genome sequence analysis showed that significant differences existed between GCRV-GD108 and GCRV, as well as other known species of aquareovirus. In this study, molecular characteristics of diseased grass carp collected from different farms i ... | 2011 | 21874906 |
| epidemiological study on clonorchis sinensis infection in shenzhen area of zhujiang delta in china. | to study the transmission route and epidemiological features of clonorchis sinensis infection in shenzhen area, which is the biggest immigration city in the south of china, we examined 1,473 individuals (710 males and 763 females) to assess the current status of c. sinensis infection among the people in a village of shenzhen in zhujiang delta of guangdong province, china. freshwater snails, 630, of different species known as the first intermediate host of c. sinensis were collected and examined ... | 2007 | 17216484 |
| monitoring and assessment of heavy metal contamination in a constructed wetland in shaoguan (guangdong province, china): bioaccumulation of pb, zn, cu and cd in aquatic and terrestrial components. | the objective of this study is to evaluate the current status of heavy metal concentrations in constructed wetland, shaoguan (guangdong, china). sediments, three wetland plants (typha latifolia, phragmites australis, and cyperus malaccensis), and six freshwater fish species [carassius auratus (goldfish), cirrhinus molitorella (mud carp), ctenopharyngodon idellus (grass carp), cyprinus carpio (wild common carp), nicholsicypris normalis (mandarin fish), sarcocheilichthys kiangsiensis (minnows)] in ... | 2017 | 27164879 |
| dietary intake of pbdes of residents at two major electronic waste recycling sites in china. | the dietary intake of polybrominated diphenyl ether (pbde) of local residents from 2 major electronic waste (e-waste) processing sites (guiyu, guangdong province and taizhou, zhejiang province) in china was investigated. seventy-four food items were collected from these sites, divided into 9 food groups (freshwater fish, marine fish, shellfish, pork, poultry, chicken offal, egg, vegetables and cereals), and examined for residual pbde concentrations. out of all food items examined, the freshwater ... | 2013 | 22819225 |
| occurrence of a lethal ranavirus in hybrid mandarin (siniperca scherzeri×siniperca chuatsi) in guangdong, south china. | a novel ranavirus with features similar to largemouth bass virus (lmbv) was isolated and then characterized from a natural mass mortality of adult hybrid mandarin (siniperca scherzeri×siniperca chuatsi). the isolated lmbv-like iridovirus was designated as mandarin ranavirus (mrv)-gd1301. the results of artificial infection showed that mrv-gd1301 was highly virulent to hybrid mandarin juveniles, and 100% mortality was observed within 5days after infection via intraperitoneal injection. moribund f ... | 2017 | 28619157 |
| dietary exposure to polychlorinated dibenzo-p-dioxins and dibenzofurans via fish consumption and dioxin-like activity in fish determined by h4iie-luc bioassay. | dietary exposure to polychlorinated dibenzo-p-dioxins and dibenzofurans (pcdd/fs) via fish consumption in two major electronic (e) waste sites: guiyu (gy), guangdong province and taizhou (tz), zhejiang province, and dioxin-like activity in fish determined by h4iie-luc bioassay. in the present study, all fish were below eu's maximum allowable concentration in muscle of fish (4 pg who-teq/g wet wt), except crucian (4.28 pg who-teq/g wet wt) and silver carps (7.49 pg who-teq/g wet wt) collected fro ... | 2013 | 22959899 |
| emergence of fatal european genotype cyhv-3/khv in mainland china. | cyprinid herpesvirus 3 (cyhv-3), also known as koi herpesvirus (khv), is a highly infectious causative agent to common carp and koi worldwide. the virus is mainly consisted of european and asian genotype isolates. to date, no european genotype cyhv-3 has been found emerging in the east and southeast asian regions. in late march 2011, an outbreak of cyhv-3 disease occurred in guangzhou city, guangdong province, china, resulting in the deaths of approximately 200 large-sized adult koi within four ... | 2013 | 23146169 |
| isolation, pathogenicity and characterization of a novel bacterial pathogen streptococcus uberis from diseased mandarin fish siniperca chuatsi. | in recent years, mandarin fish had a high mortality rate associated with abnormal swimming, exophthalmia, corneal opacity and eye hemorrhage on a fish farm located at foshan city, guangdong province, china. three isolates of gram-positive, chain-forming cocci were recovered from moribund fish, and designated as ss131025-1, ss131025-2, and ss131025-3. these isolates were identified as streptococcus uberis according to their morphologic and physio-biochemical characteristics as well as phylogeneti ... | 2017 | 28416382 |
| parasitism of argulus japonicus in cultured and wild fish of guangdong, china with new record of three hosts. | this study aimed to demonstrate the ability of argulus japonicus to infect a wide range of freshwater fishes, as well as to understand the effects of fish origin and host body size on the incidence of a. japonicus. samples of cultured and wild fish were collected randomly from july 2010 to march 2013, using angling, long-lining, gill-netting, and trapping from rivers and fish farms in guangdong province, south china. eight fish species were found to be heavily infected including the common carp, ... | 2014 | 24297692 |
