I think the easiest is to use an intermediate string. If your file is test.txt,
In [22]: a = file('test.txt').read().replace(',','.')
In [23]: import StringIO
In [24]: b=genfromtxt(StringIO.StringIO(a))
In [25]: b
Out[25]:
array([[ 0.00000000e+00, 1.22100000e-03, 1.22100000e-03,
0.00000000e+00, 1.27807600e+00, 1.60102539e+02],
[ 4.00000000e-07, 0.00000000e+00, 0.00000000e+00,
2.44100000e-03, 1.27929700e+00, 1.60000000e+02],
[ 8.00000000e-07, -1.22100000e-03, 0.00000000e+00,

1.22100000e-03, 1.27929700e+00, 1.60000000e+02],
