Many insects rely on symbiotic microbes for survival, growth, or reproduction. Over evolutionary timescales, the association with intracellular symbionts is stabilized by partner fidelity through strictly vertical symbiont transmission, resulting in congruent host and phylogenies. However, little known about how symbioses extracellular symbionts, representing majority of insect-associated microorganisms, evolve remain stable despite opportunities horizontal exchange de novo acquisition from...
Among horizontally acquired symbioses, the mechanisms underlying microbial strain- and species-level specificity remain poorly understood. Here, confocal-microscopy analyses genetic manipulation of squid-vibrio association revealed quantitative differences in a symbiont's capacity to interact with host during initial engagement. Specifically, dominant strains Vibrio fischeri, 'D-type', previously named for their dominant, single-strain colonization squid's bioluminescent organ, were compared...
Abstract Background Insects have evolved a wide range of mechanisms to defend themselves and their offspring against antagonists. One these strategies involves the utilization antimicrobial compounds provided by symbiotic bacteria protect host or its nutritional resources from pathogens parasites. In symbiosis solitary digger wasp, Philanthus triangulum (Hymenoptera, Crabronidae), bacterial symbiont ‘ Candidatus Streptomyces philanthi’ defends developing larvae producing mixture at least...
We characterized bactericidal permeability-increasing proteins (BPIs) of the squid
A man diagnosed with Stensen's duct stenosis exhibited recurrent parotid swelling, invariably during meals. Previous dilations and percutaneous radiotherapy were ineffective. Botulinum toxin (BTX) injections injected into the affected gland to regulate salivary flow reduce swelling.BTX (22.5 units) was gland. second treatment 30 units BTX carried out 7 weeks later. Two further followed after 4 months, respectively. The results scored by patient evaluated in an examination.The reported...
Extracellular bacterial symbionts communicate biochemically with their hosts to establish niches that foster the partnership. Using quantitative ion microprobe isotopic imaging (nanoscale secondary mass spectrometry [NanoSIMS]), we surveyed localization of 15 N-labelled molecules produced by bacterium Vibrio fischeri within cells symbiotic organ its host, Hawaiian bobtail squid, and compared either labelled non-specific species or amino acids. In all cases, two areas organ's epithelia were...
Animals often acquire their microbial symbionts from the environment, but mechanisms underlying how specificity of association is achieved are poorly understood. We demonstrate that conserved proton pump, V-type ATPase (VHA), plays a key role in establishment model light-organ symbiosis between squid Euprymna scolopes and its bacterial partner, Vibrio fischeri. Recruitment V. fischeri surrounding seawater mediated by juvenile-specific ciliated fields on organ's surface. These epithelia...
