The mosquito Culex (Melanoconion) cedecei is the sole enzootic vector of EVEV (2-4); rodents, particularly Peromyscus gossypinus (cotton mouse) and Sigmodon hispidus (hispid cotton rat
), are the primary reservoir hosts (5-7).
As described in the article, the oral RSV-F vaccine candidate provided complete sterilizing protection against RSV infection in the cotton rat
challenge model at the target dose.
The Everglades virus is a mosquito-borne disease carried by the hispid cotton rat
, which lives in areas with tall grass such as grassy fields, weedy areas, and marshy areas ...
One hardy species endured the invasion: the hispid cotton rat
. There are a number of theories about why the rat survived.

The second most common food of bobcats, the cotton rat
, was seldom eaten by coyotes.
(8) A rodent reservoir in the indigenous cotton rat
, Sigmodon hispidus, was suspected and established initially by a 13% seroprevalence of antihantaviral IgG antibodies in trapped cotton rats
; it was later confirmed by the detection of BCC virus RNA in seropositive rats by reverse transcriptasepolymerase chain reaction (RT-PCR) assay.
Density Estimation--We estimated Sigmodon hispidus population density using abundance (minimum number of individuals known alive) in effective trapping areas, where effective trapping area is equal to the area of a trapping grid plus a boundary strip of half the mean maximum distance moved (MMDM) by recaptured animals (Wilson and Anderson, 1985; Krebs et al., 2011).
The hispid cotton rat
(Sigmodon hispidus), which occurs in the southern United States, is the host of Black Creek Canal hantavirus (Table 1), a known cause of HPS (Rollin et al.
