The most prevalent genera of Lactococcus (31.2 %), Staphylococcus (11.7 %), Serratia (10.4 %), Acinetobacter (9.1 %), Enterococcus (7.8 %) and Pseudomonas spp. (6.5 %) were identified by means of 16S rRNA gene sequencing.
On a lower taxonomic level, the most prevalent genera were Moraxella (40%), Haemophilus (20%), Streptococcus (12%), and Flavobacterium (10%).
However, these analyses did not report whether the most prevalent genera in their mother child samples were represented by identical species.
The 17 most prevalent genera and the 6 most prevalent species are also consistent with the taxonomic structure based on mapped reads.
For archaeal species, the three most prevalent genera are Methanosarcina (6,522 reads, 2.7%), Methanoculleus (1,102 reads, 0.5%), and Methanosaeta (750 reads, 0.3%), which all belong to class Methanomicrobia of Euryarchaeota (Table 4, Figure 3C).
Analysis of all 13 865 OTUs indicated two main networks, Network A and Network B, identified at the taxonomic level of order in Figure 2. In addition, the 109 most prevalent genera (Table S4A) were characterized based on the ability of all validated species within these genera to grow by aerobic respiration.
Our results agree with previous studies [27] that identified Pheidole, Camponotus, and Crematogaster as the most prevalent ant genera globally.
As in previous studies (Chapin et al. 2005; Gibbs et al. 2004; Predicala et al. 2002), Staphylococcus was one of the most prevalent culturable genera of bacteria recovered from swine CAFOs, and it exhibited multiple antibiotic resistances.
The bats represented 15 species of 10 genera; the most prevalent (26.3%) species was the common vampire bat (Desmodus rotundus); the other 14 species accounted for 0.8%12.7%% of the bats sampled.
Iridophycan is an extract from species of the Iridea genera of algae, which are most prevalent in the waters off central California but also are present off South Africa, Japan, Chile and the Falkland Islands.
Among toxigenic genera, Aspergillus (68%) was the most prevalent, followed by Penicillium species (60%).
