| serological survey of toxoplasma gondii in wild waterfowl in chukotka, kamchatka, russia and hokkaido, japan. | antibodies to toxoplasma gondii were assayed by elisa in 22 experimentally inoculated domestic ducks. in addition, a serological assay was carried out at obihiro, hokkaido, japan, in 2004 and 2005, on 221 wild ducks of 5 species: anas platyrhynchus (n = 111); a. poecilorhyncha (n = 27); a. acuta (n = 58); a. penelope (n = 16); and a. crecca (n = 9). assays were also conducted using sera from 197 wild geese of 2 species, i.e., anser albifrons (n = 162) and ans. fabalis (n = 35). birds were collec ... | 2008 | 18576786 |
| incidence of toxoplasma gondii in populations of wild birds in the czech republic. | the protozoan parasite toxoplasma gondii was isolated from 193 individuals of 25 wild avian species, in a survey between 1981 and 90 in which 5880 individuals, comprising 76 species, were examined. the incidence of t. gondii was 18% in rooks (corvus frugilegus), 12% in mallards (anas platyrhynchos), 8% in common buzzards (buteo buteo), 2% in pheasants (phasianus colchicus) and 0.5% in house sparrows (passer domesticus) and differed significantly in these species (x(2) test, p<0.001). in rooks, t ... | 1992 | 18670984 |
| toxoplasma gondii infection in domestic ducks, free-range and caged chickens in southern china. | toxoplasma gondii is widely distributed in humans and other animals including domestic poultry throughout the world, but little is known of the prevalence of t. gondii in chickens and ducks in people's republic of china. in the present study, antibodies to t. gondii were investigated in 349 domestic ducks (anas spp.), 361 free-range, and 244 caged chickens (gallus domesticus) raised in commercial flocks in southern china's guangdong province using the modified agglutination test (mat). antibodie ... | 2009 | 19647942 |
| molecular and biological characteristics of toxoplasma gondii isolates from wildlife in france. | toxoplasma gondii isolates have been classified into 3 genetic types. little is known about genotypes of t. gondii isolates in wild animals in europe. in this report, genotypes of t. gondii isolates from wildlife in france are described. sera from wildlife were tested for antibodies to t. gondii with the modified agglutination test, and the hearts from animals with titers superior or equal to 1:6 were bioassayed individually in mice. t.gondii was isolated from 9 of 14 seropositive red foxes (vul ... | 2010 | 20417034 |
| seroprevalence of toxoplasma gondii antibodies in domestic ducks, free-range chickens, turkeys and rabbits in kafr el-sheikh governorate egypt. | in kafr el-sheikh, capital of kafr el-sheikh governorate, toxoplasma-ihat was performed on locally bred domestic ducks, free-range chickens, turkey and domestic rabbits. the results revealed an infection rate of 55, 38.1, 29.4, and 37.5% respectively which indicates a soil contamination and environmental zoonotic risk. | 2010 | 21246937 |
| prevalence of toxoplasma gondii infection in wild birds in durango, mexico. | abstract there is a lack of information concerning the prevalence of toxoplasma gondii infection in wild birds in mexico. in the present study serum samples and tissues from 653 birds from durango state, mexico were evaluated for t. gondii infection. antibodies to t. gondii (modified agglutination test, mat, titer 1:25 or higher) were found in 17 (2.6%) of the 653 birds including 1 of 2 curve-billed thrashers (toxostoma curvirostre), 2 (1 anas platyrhynchos, 1 anas diazi) of 4 ducks, 1 of 2 eagl ... | 2011 | 21612413 |
| serological survey and risk factors for toxoplasma gondii in domestic ducks and geese in lower saxony, germany. | to obtain estimates for the prevalence of toxoplasma gondii infection in ducks and geese in germany, enzyme-linked immunosorbent assays (elisa) were established based on affinity-purified t. gondii tachyzoite surface antigen 1 (tgsag1) and used to examine duck and goose sera for t. gondii-specific antibodies. the results of 186 sera from 60 non-infected ducks (anas platyrhynchos) and 101 sera from 36 non-infected geese (anser anser) as well as 72 sera from 11 ducks and 89 sera from 12 geese inoc ... | 2011 | 21719198 |
| molecular detection and genotypic characterization of toxoplasma gondii in wild waterfowls in jilin province, northeastern china. | toxoplasma gondii can infect almost warm-blooded animals, including humans. limited information about t. gondii infection in wild waterfowls is available in china. the present study was conducted to determine prevalence and genotype t. gondii infection in 11 wild waterfowl species in jilin province, northeastern china. a total of 249 wild waterfowls were sampled between april and july 2013 from jilin province, and the tissue samples were collected for the detection of t. gondii by a semi-nested ... | 2015 | 26292258 |
| toxoplasma gondii in waterfowl: the first detection of this parasite in anas crecca and anas clypeata from italy. | understanding the spread of toxoplasma gondii in waterfowl is of interest for elucidating the potential involvement of these birds in maintaining the parasitic life cycle because birds are exposed to these parasites. sera from 103 adult, free-range game birds, representing 13 different species living in the italian wetlands, were examined using modified agglutination tests for antibodies specific to t. gondii . in seropositive birds, the brain and heart were homogenized and dna was extracted to ... | 2013 | 23145510 |
