Zusammenfassung: | spp. and "
Gortzia infectiva", known as
-like bacteria (HLB), are commonly found as nuclear endosymbionts of ciliates, especially the
genus. HLB are related by phylogenetic relationships, morphological features, and life-cycles, which involve two alternating morphotypes: reproductive and infectious forms (RF, IF). In this paper we describe a novel species belonging to the "
. Gortzia" genus, detected in
, a ciliate for which infection by an HLB has not been reported, discovered in India. This novel endosymbiont shows unusual and surprising features with respect to other HLB, such as large variations in IF morphology and the occasional ability to reproduce in the host cytoplasm. We propose the name of "
Gortzia shahrazadis" for this novel HLB. Moreover, we report two additional species of HLB from Indian
populations: "
. Gortzia infectiva" (from
), and
(from
); the latter is the first record of
from a tropical country. Although tropical, we retrieved
at an elevation of 706 m corresponding to a moderate climate not unlike conditions where
are normally found, suggesting the genus
does exist in tropical countries, but restricted to higher elevations. |
