| sindbis and middelburg old world alphaviruses associated with neurologic disease in horses, south africa. | old world alphaviruses were identified in 52 of 623 horses with febrile or neurologic disease in south africa. five of 8 sindbis virus infections were mild; 2 of 3 fatal cases involved co-infections. of 44 middelburg virus infections, 28 caused neurologic disease; 12 were fatal. middelburg virus likely has zoonotic potential. | 0 | 26583836 |
| larval feeding behavior of three co-occurring species of container mosquitoes. | interspecific differences in foraging behavior may help to determine whether the outcome of interspecific competition is coexistence or exclusion. mosquitoes in the genus culex are commonly described as foraging primarily by filtering the water column. this behavior contrasts with that of other container-dwelling genera, such as aedes and ochlerotatus, that are thought to forage primarily by browsing on container and detritus surfaces. we compared the feeding behavior of cx. pipiens, ae. albopic ... | 0 | 15707290 |
| identification of mosquito avian-derived blood meals by polymerase chain reaction-heteroduplex analysis. | a polymerase chain reaction (pcr) heteroduplex assay (hda) was developed to identify avian derived mosquito blood meals to the species level. the assay used primers amplifying a fragment of the cytochrome b gene from vertebrate but not invertebrate species. in culex tarsalis fed on quail, pcr products derived from the quail cytochrome b gene were detected seven days post-engorgement. in an analysis of wild-caught mosquitoes, 85% of blood-fed mosquitoes produced detectable pcr products. heterodup ... | 0 | 12201598 |
| risk of transmission of viral haemorrhagic fevers and the insecticide susceptibilitystatus of aedes aegypti (linnaeus) in some sites in accra, ghana. | dengue is one of the emerging diseases that can mostly only be controlled by vector control since there is no vaccine for the disease. although, dengue has not been reported in ghana, movement of people from neighbouring countries where the disease has been reported can facilitate transmission of the disease. | 0 | 27752187 |

| habitat associations of eastern equine encephalitis transmission in walton county florida. | eastern equine encephalitis virus (eeev; family togaviridae, genus alphavirus) a highly pathogenic mosquito-borne virus is endemic to eastern north america. the ecology of eeev in florida differs from that in other parts of the united states; eeev in the northeastern united states is historically associated with freshwater wetlands. no formal test of habitat associations of eeev in florida has been reported. geographical information sciences (gis) was used in conjunction with sentinel chicken ee ... | 0 | 22679885 |
| eastern equine encephalitis in children, massachusetts and new hampshire,usa, 1970-2010. | we describe the clinical, laboratory, and radiographic characteristics of 15 cases of eastern equine encephalitis in children during 1970-2010. the most common clinical and laboratory features were fever, headache, seizures, peripheral leukocytosis, and cerebrospinal fluid neutrophilic pleocytosis. radiographic lesions were found in the basal ganglia, thalami, and cerebral cortex. clinical outcomes included severe neurologic deficits in 5 (33%) patients, death of 4 (27%), full recovery of 4 (27% ... | 0 | 23343480 |
| barriers to success: how baculoviruses establish efficient systemic infections. | the mechanisms used by baculoviruses to exit the midgut and cause systemic infection of their insect hosts have been debated for decades. after being ingested, baculoviruses reach the midgut, where several host barriers need to be overcome in order to establish successful infection. one of these barriers is the basal lamina, a presumably virus-impermeable extracellular layer secreted by the epithelial cells lining the midgut and trachea. this review discusses new evidence that demonstrates how t ... | 0 | 21300392 |
| development of a multiplexed polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) assay to identify common members of the subgenera culex (culex) and culex (phenacomyia) in guatemala. | morphological differentiation of mosquitoes in the subgenera culex (culex) and culex (phenacomyia) in guatemala is difficult, with reliable identification ensured only through examination of larval skins from individually reared specimens and associated male genitalia. we developed a multiplexed polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) assay to identify common cx.
