Kidney samples from the 3 antibody-positive Mexican deer mice, Mexican deer mouse TK93314 (15) and 8 other antibody-negative Mexican deer mice, 18 southern pygmy mice (Baiomys musculus), and 11 Jaliscan cotton rats
(Sigmodon mascotensis) were tested for arenavirus by cultivation in monolayers of Vero E6 cells (16).
Small mammal trapping yielded only 12 captures in 351 traps nights (7 Texas mice [Peromyscus attwateri], 2 hispid cotton rats
[Sigmodon hispidus] and 3 eastern wood rats [Neotoma floridana]).
They usually are found in association with cotton rats
(Sigmodon) and harvest mice (Reithrodontomys), and prefer grassy areas such as old fields, pastures and along railroads or highways (Schmidly 1983).
The male short-tailed cane mice, female short-tailed cane mice, male Alston's cotton rats
, and female Alston's cotton rats
were assigned on the basis of their nose-to-rump lengths (measured in mm) to 4 size categories.
The majority of tests of choice (153 trials; 79%) involved North American deermice, whereas the remaining 40 tests involved a mixture of white-footed deermice (n = 21 tests), western harvest mice (n = 13), prairie voles (n = 2), hispid cotton rats
(n = 2), and thirteen-lined ground squirrels (n = 2).
In this coastal prairie habitat, reproductive female cotton rats
prefer mixed patches and avoid dicot patches (Kincaid and Cameron, 1985; Cameron and Spencer, 2008).
-- An effort of 628 trapnights in this habitat yielded two cotton rats
, one pygmy mouse and one least shrew.
In 1991, Stangl and Dalquest (1991) published a reexamination of fossil first upper molars of cotton rats
from Pleistocene deposits in Fowlkes Cave in southern Culberson County, Texas, and from deposits from Pratt Cave, Culberson County, at the southern end of the Guadalupe Mountains.
cedecei mosquitoes were more abundant (Figure 2, panel A) and obtained a large number of blood meals from cotton rats
(Figure 2, panel B).
The SAM technology has already proven successful against various disease targets like HIV, RSV, CMV, and influenza, and in animal models including mice, cotton rats
, ferrets, and non-human primates.
What do mosquitoes, hispid cotton rats
, and Burmese pythons have in common?
