| vector competence of aedes albopictus from houston, texas, for dengue serotypes 1 to 4, yellow fever and ross river viruses. | a combination of virus infection and transmission experiments showed that a houston, texas strain of aedes albopictus is a competent vector for dengue (den), yellow fever (yf) and ross river (rr) viruses. however, at 14 days incubation, den virus infection rates in a puerto rican strain of aedes aegypti were significantly higher for each of the four den serotypes, except den-1, than in houston ae. albopictus fed simultaneously on the same virus suspensions. the degree of correlation between diss ... | 1987 | 2849638 |
| variation in the vector competence of geographic strains of aedes albopictus for dengue 1 virus. | eight geographic strains of aedes albopictus from asia and north america and one north american strain of aedes aegypti were tested for their vector competence with dengue 1 virus. three groups of ae. albopictus were established based on their vector competence: a) the oahu laboratory strain, b) the three malaysian strains, and c) the tokyo and three north american strains. the three north american strains were similar to the strain of ae. aegypti from houston, texas in their ability to transmit ... | 1987 | 3504922 |
| dengue fever at the u.s.-mexico border, 1995-1996. | dengue is a mosquito-transmitted acute disease caused by any of four virus serotypes (den-1, den-2, den-3 and den-4) and is characterized by acute manifestations that can include fever, headache, myalgia, arthralgia, rash, nausea, and vomiting. on august 25, 1995, public health authorities in mexico notified the texas department of health (tdh) of an ongoing outbreak of dengue fever in the state of tamaulipas, which borders south texas. because of the year-round presence of the aedes aegypti mos ... | 1996 | 8927003 |
| texas lifestyle limits transmission of dengue virus. | urban dengue is common in most countries of the americas, but has been rare in the united states for more than half a century. in 1999 we investigated an outbreak of the disease that affected nuevo laredo, tamaulipas, mexico, and laredo, texas, united states, contiguous cities that straddle the international border. the incidence of recent cases, indicated by immunoglobulin m antibody serosurvey, was higher in nuevo laredo, although the vector, aedes aegypti, was more abundant in laredo. environ ... | 2003 | 12533286 |
| variation in vector competence for dengue viruses does not depend on mosquito midgut binding affinity. | dengue virus genotypes of southeast asian origin have been associated with higher virulence and transmission compared to other genotypes of serotype 2 (den-2). we tested the hypothesis that genetic differences in dengue viruses may result in differential binding to the midgut of the primary vector, aedes aegypti, resulting in increased transmission or vectorial capacity. | 2011 | 21610852 |
