“…These observations could indicate gene flow between Groups 4 and 5 and, based on the lack of other MtrC duplicates in Acidobacteriia, could represent a previous loss event that removed what might have been a functionally irrelevant paralog. Such instances of genome reduction by paralog loss are not uncommon and have been well studied in other systems ( 94 – 96 ) in which a gene is duplicated and subsequently neofunctionalized, followed by a loss of one of the two copies.…”

While many metabolisms make use of soluble, cell-permeable substrates like oxygen or hydrogen, there are other substrates, like iron or manganese, that cannot be brought into the cell. Some bacteria and archaea have evolved the means to directly “plug in” to such environmental electron reservoirs in a process known as extracellular electron transfer (EET), making them powerful agents of biogeochemical change and promising vehicles for bioremediation and alternative energy.

“…Although not well-supported by bootstrap value, this cluster was distinct from other Bartonella and Rhizobiales bacteria. It has been reported that 16S rRNA is not a suitable marker for Bartonella ( La Scola et al, 2003 ) because of the existence of multiple copies in its genome ( Viezens and Arvand, 2008 ; Banerjee et al, 2020 ). To distinguish whether Bartonella sp.…”

The poultry red mite Dermanyssus gallinae poses a significant threat to the health of hens and poultry production. A comprehensive understanding of D. gallinae is necessary to develop sustainable and efficacious control methods. Here we examined 144 D. gallinae collected from 18 poultry farms throughout the Japanese Archipelago for their genetic variations based on mitochondrial cytochrome c oxidase subunit I (COI) sequences, and microbiome variations based on amplicon sequencing of the 16S ribosomal RNA gene. According to COI sequencing, the Japanese samples were categorized into three haplogroups, which did not reflect the geographical distribution. Microbiome analyses found that the major bacteria associated with D. gallinae were Bartonella, Cardinium, Wolbachia, and Tsukamurella, with Bartonella being most predominant. Among 144 individual mites, all possessed one of the two major types of Bartonella (Bartonella sp. A), while 140 mites possessed the other type (Bartonella sp. B). The presence of the two strains of Bartonella was also confirmed by a single copy gene, rpoB. The presence of Bartonella in laid eggs suggested transovarial vertical transmission. Given that obligate blood-feeding arthropods generally require a supply of B vitamins from symbiotic bacteria, Bartonella may play an important role in mite survival. Rickettsiella, a major symbiont in European D. gallinae populations, and suggested to be an important symbiont by genomic data, was rarely found in Japanese populations. Cardinium detected from D. gallinae fell into a major clade found widely in arthropods, whereas Wolbachia detected in Japanese D. gallinae appear to be a new lineage, located at the base of Wolbachia phylogeny. Of the mitochondrial phylogeny, infection patterns of Cardinium and Wolbachia were strongly correlated, possibly suggesting one or both of the symbionts induce reproductive manipulations and increase spread in the host populations.

“…Overall, there are up to 45 different Bartonella spp. reported globally with approximately 13 species known to be zoonotic ( Harms and Dehio, 2012 ; Okaro et al, 2017 ; Banerjee et al, 2020 ). For other species of Bartonella it is documented that companion animals can act as reservoirs for human infection ( Chomel et al, 2006 ) and therefore, it is plausible that the Mongolian B. rochalimae -infected dogs could present a reservoir for human infections.…”
