Symbiotic Wolbachia in mosquitoes and its role in reducing the transmission of mosquito-borne diseases: updates and prospects. Front Microbiol 2023; 14:1267832.

Abstract
Mosquito-borne diseases such as malaria, dengue fever, West Nile virus, chikungunya, Zika fever, and filariasis have the greatest health and economic impact. These mosquito-borne diseases are a major cause of morbidity and mortality in tropical and sub-tropical areas. Due to the lack of effective vector containment strategies, the prevalence and severity of these diseases are increasing in endemic regions. Nowadays, mosquito infection by the endosymbiotic Wolbachia represents a promising new bio-control strategy. Wild-infected mosquitoes had been developing cytoplasmic incompatibility (CI), phenotypic alterations, and nutrition competition with pathogens. These reduce adult vector lifespan, interfere with reproduction, inhibit other pathogen growth in the vector, and increase insecticide susceptibility of the vector. Wild, uninfected mosquitoes can also establish stable infections through trans-infection and have the advantage of adaptability through pathogen defense, thereby selectively infecting uninfected mosquitoes and spreading to the entire population. This review aimed to evaluate the role of the Wolbachia symbiont with the mosquitoes (Aedes, Anopheles, and Culex) in reducing mosquito-borne diseases. Global databases such as PubMed, Web of Sciences, Scopus, and pro-Quest were accessed to search for potentially relevant articles. We used keywords: Wolbachia, Anopheles, Aedes, Culex, and mosquito were used alone or in combination during the literature search. Data were extracted from 56 articles' texts, figures, and tables of the included article.

Abstract
The legitimacy, spelling and grammatical gender of names of classes validly published under the International Code of Nomenclature of Prokaryotes (ICNP) is reviewed in the aftermath of the decision to make Rule 8 of the ICNP non-retroactive regarding the formation of such names. This ruling removed most of the nomenclatural uncertainty that affected names of classes but some issues remain to be solved. Some previously legitimate names of classes became illegitimate by this decision while others retained their illegitimacy. The Judicial Commission is asked to conduct according clarifications. It is proposed to place the names at the rank of class

Saini N, Gupta RS. A robust phylogenetic framework for members of the order Legionellales and its main genera (Legionella, Aquicella, Coxiella and Rickettsiella) based on phylogenomic analyses and identification of molecular markers demarcating different clades. Antonie van Leeuwenhoek 2021; 114:957-982. [PMID: 33881638 DOI: 10.1007/s10482-021-01569-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 04/01/2021] [Indexed: 12/29/2022]
Abstract
The order Legionellales contains several clinically important microorganisms. Although members of this order are well-studied for their pathogenesis, there is a paucity of reliable characteristics distinguishing members of this order and its constituent genera. Genome sequences are now available for 73 Legionellales species encompassing ≈90% of known members from different genera. With the aim of understanding evolutionary relationships and identifying reliable molecular characteristics that are specific for this order and its constituent genera, detailed phylogenetic and comparative analyses were conducted on the protein sequences from these genomes. A phylogenomic tree was constructed based on 393 single copy proteins that are commonly shared by the members of this order to delineate the evolutionary relationships among its members. In parallel, comparative analyses were performed on protein sequences from Legionellales genomes to identify novel molecular markers consisting of conserved signature indels (CSIs) that are specific for different clades and genera. In the phylogenomic tree and in an amino acid identity matrix based on core proteins, members of the genera Aquicella, Coxiella, Legionella and Rickettsiella formed distinct clades confirming their monophyly. In these studies, Diplorickettsia massiliensis exhibited a close relationship to members of the genus Rickettsiella. The results of our comparative genomic analyses have identified 59 highly specific molecular markers consisting of CSIs in diverse proteins that are uniquely shared by different members of this order. Four of these CSIs are specific for all Legionellales species, except the two deeper-branching "Candidatus Berkiella" species, providing means for identifying members of this order in molecular terms. Twenty four, 7 and 6 CSIs are uniquely shared by members of the genera Legionella, Coxiella and Aquicella, respectively, identifying these groups in molecular terms. The descriptions of these three genera are emended to include information for their novel molecular characteristics. We also describe 12 CSIs that are uniquely shared by D. massiliensis and different members of the genus Rickettsiella. Based on these results, we are proposing an integration of the genus Diplorickettsia with Rickettsiella. Three other CSIs suggest that members of the genera Coxiella and Rickettsiella shared a common ancestor exclusive of other Legionellales. The described molecular markers, due to their exclusivity for the indicated taxa/genera, provide important means for the identification of these clinically important microorganisms and for discovering novel properties unique to them.

Abstract
The attention of the Judicial Commission was drawn to issues relating to the use of names at the rank of class, subclass and order and the nomenclatural type of names at the rank of class and subclass that were not covered by Opinion 79. The Judicial Commission ruled that names at the rank of class and order proposed by Cavalier-Smith (Int. J. Syst. Evol. Microbiol., 52, 7–76, 2002) are to be placed on the List of Rejected Names (nomina rejicienda) and the use of names proposed in that publication above the rank of class is to be actively discouraged. In addition a list of names at the rank of class, subclass and order is given where the nomenclatural type, description or circumscription is unclear or where they otherwise appear to be not in accordance with the Rules of the International Code of Nomenclature of Bacteria.

Discovery of novel Rickettsiella spp. in ixodid ticks from Western Canada. Appl Environ Microbiol 2013; 80:1403-10.

Abstract
The genomic DNA from four species of ixodid ticks in western Canada was tested for the presence of Rickettsiella by PCR analyses targeting the 16S rRNA gene. Eighty-eight percent of the Ixodes angustus (n = 270), 43% of the I. sculptus (n = 61), and 4% of the I. kingi (n = 93) individuals examined were PCR positive for Rickettsiella, whereas there was no evidence for the presence of Rickettsiella in Dermacentor andersoni (n = 45). Three different single-strand conformation polymorphism profiles of the 16S rRNA gene were detected among amplicons derived from Rickettsiella-positive ticks, each corresponding to a different sequence type. Furthermore, each sequence type was associated with a different tick species. Phylogenetic analyses of sequence data of the 16S rRNA gene and three other genes (rpsA, gidA, and sucB) revealed that all three sequence types were placed in a clade that contained species and pathotypes of the genus Rickettsiella. The bacterium in I. kingi represented the sister taxon to the Rickettsiella in I. sculptus, and both formed a clade with Rickettsiella grylli from crickets (Gryllus bimaculatus) and "R. ixodidis" from I. woodi. In contrast, the Rickettsiella in I. angustus was not a member of this clade but was placed external to the clade comprising the pathotypes of R. popilliae. The results indicate the existence of at least two new species of Rickettsiella: one in I. angustus and another in I. kingi and I. sculptus. However, the Rickettsiella strains in I. kingi and I. sculptus may also represent different species because each had unique sequences for all four genes.

Abstract
'Rickettsiella melolonthae' is an intracellularly multiplying bacterial pathogen of European cockchafers, Melolontha melolontha (Linnaeus, 1758) and Melolontha hippocastani (Fabricius, 1801) (Coleoptera: Scarabaeidae). We report the first determination of nucleotide sequences from this organism, i.e. the 16S rRNA encoding rrs gene, the chaperonin encoding groEL gene and the mucZ gene encoding the orthologue of a capsule synthesis-inducing factor of Coxiella burnetii. Within the genus Rickettsiella, the pathotype 'Rickettsiella melolonthae' is currently classified as a synonym of the nomenclatural type species Rickettsiella popilliae. Previous sequencing of a 16S rRNA gene from a different species, Rickettsiella grylli, has motivated the transfer of the entire genus from the alphaproteobacterial order Rickettsiales to the gammaproteobacterial order Legionellales, family Coxiellaceae. We investigated the validity of this taxonomic reorganization beyond the species Rickettsiella grylli by reconstructing the organismal phylogeny from comparisons of 16S rRNA gene and GroEL and MucZ protein sequences from a selected set of alpha- and gammaproteobacteria as well as bacterial pathogens from the order Chlamydiales. Our analysis strongly supported the transfer of the genus Rickettsiella to the order Legionellales, but not its classification in one of the recognized families present in this order. Furthermore, our results substantiated inconsistencies in the internal organization of the genus. In particular, the currently accepted delineation of Rickettsiella species and the claimed synonymy of 'Rickettsiella melolonthae' with Rickettsiella popilliae are not simultaneously consistent with our findings.

Abstract
The genus Rickettsiella (class Gammaproteobacteria; order Legionellales; family Coxiellaceae) comprises intracellular bacterial pathogens of a wide range of arthropods that are currently classified in the three recognized species, Rickettsiella popilliae, Rickettsiella grylli, and Rickettsiella chironomi. Rickettsiella bacteria contain a type IVB secretion system (T4SS) known to be a key virulence factor of the related genus Legionella. Providing the first respective sequence information for the nomenclatural type species, R. popilliae, the three T4SS components DotA, IcmB, and IcmQ were used as phylogenetic markers to test hypotheses implicit in the currently accepted taxonomic organization of Rickettsiella at the species, genus, and family level. These results, firstly, firmly corroborate the previous 16S rRNA gene-based coassignment of the species R. grylli and R. popilliae to the gamma-proteobacterial order Legionellales and, secondly, support the current classification of the investigated R. grylli and R. popilliae strains in different species of the same genus. In contrast, the analysis of intergeneric sequence distances does not lend support to the current taxonomic classification of the genus Rickettsiella in the family Coxiellaceae, but is consistent with a hierarchically neutral family-level assignment within the order Legionellales.

Abstract
The putative role of biting flies in Bartonella transmission among ruminants was investigated. Amplification of the Bartonella citrate synthase gene from 83 Hippoboscidae was detected in 94% of 48 adult Lipoptena cervi flies, 71% of 17 adult Hippobosca equina flies, 100% of 20 adult Melophagus ovinus flies, and 100% of 10 M. ovinus pupae. Our findings suggest that Hippoboscidae play a role in the transmission of Bartonella among ruminants. The vertical transmission of Bartonella in M. ovinus and the presence of Bartonella DNA in all samples suggest a symbiotic association between Bartonella and M. ovinus.
