Caged virgin and mated queens isolated from direct contact with workers
tended to have more bacteria. Isolation from workers also led to fewer
bacterial species than those in contact with workers. (But look at the
mean separation letters at the top of Figure 2- a bit murky). And
workers had higher bacterial counts and richer bacterial communities.
First paragraph of Results:
All non-isolated queens, both virgin and mated (NVQs and NMQs), had
significantly fewer average 16S rRNA gene copies and lower alpha
diversity (as measured by the Effective Number of Species) compared to
4-day-old (W4s) and 14-day-old (W14s) workers (Fig 2
<http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0200527#pone-0200527-g002>).
Also, NMQs had significantly fewer 16S rRNA gene copies and a lower
Effective Number of Species than any isolated (IVQs and IMQs) queens (Fig
2A and 2B
<http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0200527#pone-0200527-g002>; p<0.05,
Tukey’s HSD for 16S rRNA copies and Games-Howell multiple comparisons
test for alpha diversity). IVQs had similar 16S rRNA gene copy numbers
compared to either IMQs or W4s and W14s (Fig 2A
<http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0200527#pone-0200527-g002>; p>0.05,
Tukey’s HSD). Thus, isolating queens during the first few days
following eclosure results in a later elevation of gut bacteria
numbers.
