Three strains of a new Phlebotomus fever group virus were isolated from pack rats (Neotoma micropus) collected in south Texas during 1973--1974; the name Rio Grande was proposed for this virus. The virus is pH 3.0 labile, sensitive to the action of sodium deoxycholate and heat (56 degrees C) labile. The results of a serosurvey indicated that pack rats are probably the principal vertebrate host for Rio Grande virus and that year-round transmission of the virus may occur. Because no isolations of this virus were made from hematophagous insects, the vector, if any, remains undetermined.
1973年至1974年期间，从得克萨斯州南部捕获的林鼠（小林鼠）中分离出三株新型白蛉热群病毒；该病毒被命名为里奥格兰德病毒。该病毒在pH 3.0时不稳定，对脱氧胆酸钠的作用敏感，对热（56摄氏度）也不稳定。血清学调查结果表明，林鼠可能是里奥格兰德病毒的主要脊椎动物宿主，且该病毒可能全年传播。由于未从吸血昆虫中分离出该病毒，因此其传播媒介（如有）仍未确定。
