Amycolatopsis palatopharyngis sp. nov., a potentially pathogenic actinomycete isolated from a human clinical source

Abstract

The taxonomic position of an actinomycete, strain 1BDZ T , isolated from a clinical human source was determined using a polyphasic approach. Phylogenetic analysis based on almost complete 16S rDNA sequences showed that this organism consistently formed a distinct line with the Amycolatopsis methanolica subclade within the genus Amycolatopsis, and shared moderately low 16S rDNA similarity (<96?5 %) with other species. The organism was also found to have chemical and morphological properties typical of members of the genus Amycolatopsis. A range of phenotypic characteristics readily distinguished this strain from representatives of all species of Amycolatopsis with validly published names. On the basis of these data, a novel species, Amycolatopsis palatopharyngis sp. nov., is proposed to accommodate strain 1BDZ T

“…The genus Amycolatopsis was first established by Lechevalier et al (1986) and was classified in the family Pseudonocardiaceae, suborder Pseudonocardineae (Stackebrandt et al, 1997). At the time of writing, it comprises 41 recognized species, most of which have been described in the past few years: Amycolatopsis australiensis (Tan et al, 2006), A. benzoatilytica (Majumdar et al, 2006), A. decaplanina (Wink et al, 2004), A. echigonensis (Ding et al, 2007), A. jejuensis (Lee, 2006), A. halotolerans (Lee, 2006), A. lurida (Lechevalier et al, 1986;Stackebrandt et al, 2004), A. marina (Bian et al, 2009), A. minnesotensis (Lee et al, 2006), A. nigrescens (Groth et al, 2007), A. niigatensis (Ding et al, 2007), A. palatopharyngis (Huang et al, 2004), A. plumensis (Saintpierre-Bonaccio et al, 2005), A. regifaucium (Tan et al, 2007), A. rifamycinica (Bala et al, 2004), A. saalfeldensis (Carlsohn et al, 2007), A. taiwanensis (Tseng et al, 2006), A. tucumanensis (Albarracín et al, 2010) and A. ultiminotia (Lee, 2009). These species are non-halophilic actinomycetes, and have been isolated from geographically diverse soils, clinical material, vegetable matter, the wall of a hypogean cave, and ocean sediment.…”

Amycolatopsis anabasis sp. nov., a novel endophytic actinobacterium isolated from roots of Anabasis elatior

“…The genus was first proposed by Lechevalier et al [1] and the genus description was emended by Lee [2] in 2009, and then by Tang et al [3] in 2010, further recently by Nouioui et al [4] in 2018. Members of the genus Amycolatopsis have been isolated from a wide variety of environmental sources, such as soil [5], salt mine [6], salt lake [3], cave [7], ocean sediment [8], catacomb [9], human sources [10] and plant tissues [11]. At the time of writing this article, the genus Amycolatopsis encompasses 76 species with validly published names and four subspecies (LPSN, http://www.…”

Amycolatopsis endophytica sp. nov., a novel endophytic actinomycete isolated from oil-seed plant Jatropha curcas L.

“…At the time of writing, the genus Amycolatopsis comprises 45 species with validly published names. The species of the genus have been isolated from various environments such as clinical material, soils, catacomb, ocean sediment, polluted environments and surface-sterilzed roots of plant (Labeda et al 2003;Huang et al 2004; Qian Miao and Sheng Qin contributed equally to this work.…”
