Table 2 Observed and expected numbers of co-infected ticks from each heterologous infection group at each time point post-secondary infection. Results of Fisher’s exact test comparing expected and observed co-infection prevalence given (odds ratio, P-value)

From: Closely-related Borrelia burgdorferi (sensu stricto) strains exhibit similar fitness in single infections and asymmetric competition in multiple infections
