As for phage evolution, bacterial evolution depended on phage isolate identity (bacteria type × phage isolate origin interaction: F3,28 = 4.5, P = 0.0328; Table S1).
Statistical analysis showed that responses to selection in the phage varied with isolate identity (phage type × phage isolate origin interaction: F3,28 = 22.1, P < 0.0001; Table S1).
However, a chick-origin TMUV isolate, originally named Sitiawan virus, can cause encephalitis and retarded growth in broiler chicks (8 ).
Analysis of Variance of bacterial cell density (log-transformed), comparing ancestral t0 and evolved t6 phages (phage type) for different phage isolate origins (PEV2, LUZ7, 14/1 or LKD16).
Logistic regression analysis of variation in infection capacity for different phage isolate origins (PEV2, LUZ7, 14/1, LKD16), bacteria type (ancestral t0 vs. evolved t1) and phage type (ancestral t0 vs. passaged t6), in experiment 1. Table S2.
Now researchers believe they have isolated the origin of desert varnish, a glassy coating on rocks and canyon walls.

Superclusters can be colored according to bacterial species or isolate origin, and sets of clusters containing isolates from a given species or source can be jointly highlighted.
Genotypic correlations, calculated separately per isolate origin and temperature treatment, were almost all positive (seven of eight), with a mean effect size of 0.35 (±0.13 SE).
Across isolates, there was a significant positive relationship between germination rate and infectivity (ancova of infectivity, with temperature and isolate origin as cofactors and germination rate as covariate: F1,62 = 8.40, P = 0.0052).
