| avian and mammalian hosts for spirochete-infected ticks and insects in a lyme disease focus in connecticut. | spirochetes and their vectors and reservoirs were studied in a lyme disease focus in east haddam, connecticut, from mid-may through september 1983. ixodes dammini subadults were comparable in number on white-footed mice (peromyscus leucopus) (means = 2.9 +/- 3.6 sd) to those on 27 different species of birds (means = 2.3 +/- 4.2 sd) representing 11 families within the order passeriformes. less commonly found ticks on birds (means less than or equal to 0.1) were immature ixodes dentatus and haemap ... | 1984 | 6516460 |
| avian communal roosts as amplification foci for west nile virus in urban areas in northeastern united states. | west nile virus (wnv) perpetuates in an enzootic transmission cycle involving culex mosquitoes and virus-competent avian hosts. in the northeastern united states, the enzootic vectors, cx. pipiens and cx. restuans, feed preferentially on american robins (turdus migratorius), suggesting a key role for this bird species in the wnv transmission cycle. we examined the role of american robin communal roosts as virus amplification foci in greater new haven, connecticut. robin communal roosts were loca ... | 2010 | 20134014 |
| vector-host interactions of culex pipiens complex in northeastern and southwestern usa. | studies on the vector-host interactions of culex pipiens complex mosquitoes by sequencing portions of mitochondrial cytochrome b gene indicate that cx. p. pipiens f. pipiens predominantly feed on avian hosts (93.1%), and focus feeding activity on several key bird species, in particular the american robin, the gray catbird, and the house sparrow in connecticut. however, cx. p. quinquefasciatus indiscriminately feed on both birds and mammals. culex p. quinquefasciatus in harris county - texas and ... | 2012 | 23401953 |
| host-feeding patterns of potential mosquito vectors in connecticut, u.s.a.: molecular analysis of bloodmeals from 23 species of aedes, anopheles, culex, coquillettidia, psorophora, and uranotaenia. | we evaluated the blood-feeding patterns in several mosquito species that may serve as vectors of disease agents in the northeastern united states. blood-fed mosquitoes were collected from 91 different sites throughout connecticut over a 6-yr period (june-october 2002-2007), and the host-feeding patterns of 23 mosquito species representing six genera were examined by using a polymerase chain reaction-based assay and sequencing portions of the cytochrome b gene of mitochondrial dna. this study was ... | 2008 | 19058640 |
| identification of avian- and mammalian-derived bloodmeals in aedes vexans and culiseta melanura (diptera: culicidae) and its implication for west nile virus transmission in connecticut, u.s.a. | to evaluate the host-feeding patterns of aedes vexans (meigen) and culiseta melanura (coquillett) as secondary vectors of west nile virus (family flaviviridae, genus flavivirus, wnv) in northeastern united states, we identified the source of vertebrate bloodmeals by sequencing portions of the cytochrome b gene of mitochondrial dna. analysis of polymerase chain reaction products from a total of 119 ae. vexans revealed that 92.4% of individuals acquired blood solely from mammalian and 2.5% from av ... | 2006 | 17017250 |
