| occurrence and attempted transmission of toxoplasma gondii in european starlings (sturnus vulgaris). | serums of 563 fledgling starlings (sturnus vulgaris) trapped during a 14 month period near lodi, california were examined for antibodies to toxoplasma gondii using the microtiter indirect hemagglutination method. titers ranging from 1:64 to 1:512 were found in 4.8% of the birds. starlings collected during may through october had a higher prevalence of antibody than those collected during november through april. rats inoculated with individual heart and brain suspensions from 10 seropositive star ... | 1978 | 650781 |
| the prevalence of serum antibodies to toxoplasma gondii in ontario mammals. | the prevalence of seropositive reactions to toxoplasma gondii was studied in farm animals, companion animals, wild rodents and birds. of the animals tested, 17% of cattle, 65% of sheep, 45% of pigs, 9% of horses, 33% of dogs and 20% of cats were seropositive by the sabin-feldman dye test. in addition 11% of mice (mus musculus), 5% of deer mice (peromyscus), 3% of rats (rattus norvegicus) and less than 2% of sparrows (passer domestcus) were seropositive. all samples from short-tailed field mice ( ... | 1978 | 667705 |
| detection and genotyping of toxoplasma gondii strains isolated from birds in the southwest of iran. | 1. the aim of this work was to determine the frequency of occurrence of toxoplasma gondii and genetically analyse isolates from a number of avian hosts in the southwest of iran (khuzestan province). the frequency of t. gondii was determined in free-range chickens (gallus domesticus), sparrows (passer domesticus), pigeons (columba livia) and starlings (sturnus vulgaris). 2. isolates obtained from toxoplasma-infected birds were subjected to molecular typing by pcr-restriction fragment length polym ... | 2013 | 23444856 |
