RESUMO
Interactions between hosts and their resident microbial communities are a fundamental component of fitness for both agents. Though recent research has highlighted the importance of interactions between animals and their bacterial communities, comparative evidence for fungi is lacking, especially in natural populations. Using data from 49 species, we present novel evidence of strong covariation between fungal and bacterial communities across the host phylogeny, indicative of recruitment by hosts for specific suites of microbes. Using co-occurrence networks, we demonstrate marked variation across host taxonomy in patterns of covariation between bacterial and fungal abundances. Host phylogeny drives differences in the overall richness of bacterial and fungal communities, but the effect of diet on richness was only evident in the mammalian gut microbiome. Sample type, tissue storage and DNA extraction method also affected bacterial and fungal community composition, and future studies would benefit from standardized approaches to sample processing. Collectively these data indicate fungal microbiomes may play a key role in host fitness and suggest an urgent need to study multiple agents of the animal microbiome to accurately determine the strength and ecological significance of host-microbe interactions.

The efficiency of the termite Macrotermes bellicosus at digesting lignocellulose is due to its gut bacterial symbionts. We report the metagenome-assembled genome sequence of Burkholderia cepacia UJ_SKK_1.2, reconstructed from metagenomes produced from Macrotermes bellicosus gut microbiota. The 7,460,271-bp genome obtained consists of 6,763 protein-coding sequences, with 6,719 functionally assigned genes and 59 RNA genes.
RESUMO
The metagenome-assembled genome (MAG) sequence of Stenotrophomonas maltophilia strain UJ_SKK_5.5 was obtained from the gut microbiome of Macrotermes bellicosus (termite) from hot, arid Nigeria. The assembled genome (4,313,335 bp) contains 157 contigs, the N50 is 41,072 bp, the GC content is 66.57%, and there are 3,925 protein coding sequences, 3,886 proteins with functional assignments, 39 pseudogenes, and 67 RNA genes.
RESUMO
The metagenome-assembled genome sequence of Olivibacter sp. strain UJ_SKK_5.1 was generated from the metagenome of a Macrotermes bellicosus (termites) gut collected from Nigeria's hot, arid environment. The assembled genome (6,135,249 bp) contains 432 contigs, with an N50 value of 22,779 bp, GC content of 41.1%, 5,043 protein-coding sequences, 5,034 proteins with functional assignments, and 9 pseudogenes and 48 RNA genes.
