Host ranges of ASLV subgroups A to D^a in New World quails

Host	% GFP-positive cells 2, 4 days after infectionb with the following virus:
	RCASBP(A)GFP	RCASBP(B)GFP	RCASBP(C)GFP	RCASBP(D)GFP
Chicken (DF1)	45.4, 68.8	96.9, 99.7	99.9, 100	99.6, 99.5
Northern bobwhite	<0.05, <0.05	<0.05, <0.05	0.39, 0.47	0.06, 0.09
Mountain quail	<0.05, <0.05	<0.05, <0.05	9.7, 12.3	0.21, 0.10
California quail	<0.05, <0.05	<0.05, <0.05	<0.05, <0.05	0.08, 0.10
Gambel's quail	<0.05, <0.05	<0.05, <0.05	2.93, 10.87	<0.05, 0.07

^aRCASBP(A)GFP enters the host cells through the Tva receptor, RCASBP(B)GFP and RCASBP(D)GFP through the Tvb receptor, and RCASBP(C)GFP through the Tvc receptor.

^bA value of 0.05% for GFP-positive cells represents the natural autofluorescence of mock-infected cells. All results are averages for two parallel infections. The standard deviation was calculated for each average value and reached only low values between ±0.016 and 0.029 (not shown).
