Table 3.
Infection prevalence determined by kDNA-PCR, RibDNA-PCR and SatDNA-PCR in wild howlers from Estación Biológica Corrientes (EBCo), Isla Brasilera (IB), San Cayetano (SC), and Isla del Cerrito (IC). Data presented as percentage, with 95% confidence intervals.

| RibDNA | 11/11 | 40/42 | 95.2 (83.83–99.42) |
| SatDNA | 3/8 | 3/19b | 15,8 (3.38–39.58) |
| IB (remote) | |||
| kDNA | 13/15 | 22/49 | 44.9 (30.66–59.77) |
| RibDNA | 15/15 | 48/49 | 98 (89.14–99.95) |
| SatDNA | 3/13 | 3/22b | 13.6 (2.90–34.92) |
| SC (village) | |||
| kDNA | 4/5 | 8/16 | 50 (24.65–75.35) |
| RibDNA | 5/5 | 15/16 | 93.8 (69.76–99.85) |
| SatDNA | 1/4 | 1/8b | 12.5 (0.31–52.66) |
| IC (village) | |||
| kDNA | 1/1 | 1/2 | a |
| RibDNA | 1/1 | 2/2 | a |
| SatDNA | 0/1 | 0/1 | a |
a
Prevalence was not estimated due to the very limited sample size.
b
Sat-DNA PCR was carried out only in kDNA-PCR-positive samples.
