| field investigation of mycoplasma gallisepticum infections in house finch (carpodacus mexicanus) eggs and nestlings. | we conducted a field study to investigate the occurrence of mycoplasma gallisepticum (mg) in eggs and nestlings from nests of house finches (carpodacus mexicanus). forty-three nests were located between the months of april and august 1998 and were followed with one to three sampling efforts. vitelline membrane of fresh eggs, whole embryos, or swabs from the choanal cleft or conjunctiva of nestlings were inoculated into mycoplasma broth for mg isolation and polymerase chain reaction (pcr) testing ... | 1999 | 10494429 |
| mycoplasmal conjunctivitis in songbirds from new york. | a field study was conducted to determine the prevalence of conjunctivitis and mycoplasma gallisepticum (mg) infections in house finches (carpodacus mexicanus) and other songbirds common to bird feeders in tompkins county (new york, usa). eight hundred two individuals of 23 species and nine families of birds were captured and given physical examinations during the 14 mo study beginning in february 1998. clinical conjunctivitis (eyelid or conjunctival swelling, erythema, and discharge) was observe ... | 2000 | 10813607 |
| vectest as diagnostic and surveillance tool for west nile virus in dead birds. | the vectest antigen-capture assay for west nile virus was performed on oral and tissue swabs from dead birds in new york state from april 2003 through july 2004. results were compared with those from real-time reverse transcriptase-polymerase chain reaction of kidney or brain. oral vectest sensitivity is adequate for surveillance in american crows (corvus brachyrhynchos) (87%), blue jays (cyanocitta cristata) (80%), and house sparrows (passer domesticus) (76%). oral vectest performed well for sm ... | 2004 | 15663856 |
| blood parasites of house finches (carpodacus mexicanus) from georgia and new york. | this study investigated the ecology of hematozoan parasites in two eastern populations of house finch (carpodacus mexicanus). blood smears were obtained from birds captured in georgia during 2001-2003 (n = 757) and new york during 2001 (n = 282) and evaluated for the presence of hematozoans. low-density infections of haemoproteus fringillae and plasmodium relictum were confirmed at each location. infections were observed year-round in georgia, but primarily between june and november in new york. ... | 2008 | 18436682 |
| identification of bloodmeals in anopheles quadrimaculatus and anopheles punctipennis from eastern equine encephalitis virus foci in northeastern u.s.a. | the host-feeding patterns of anopheles quadrimaculatus say and anopheles punctipennis (say) were examined in order to evaluate their potential contributions to the transmission of eastern equine encephalitis virus (eeev) and other arboviruses in the northeastern u.s.a. engorged mosquitoes of the two species were collected from eeev foci in central new york (ny) and throughout new jersey (nj), and their bloodmeals were identified using a polymerase chain reaction (pcr)-based assay and sequencing ... | 2009 | 19941600 |
