We report the 4,385,577-bp high-quality draft assembly of the bacterial symbiont Rhodococcus rhodnii strain LMG5362, isolated from the gut of Rhodnius prolixus (Hemiptera, Reduviidae, Triatominae), the principle vector of the protozoan Trypanosoma cruzi, the etiological agent of Chagas disease. This sequence might provide useful information for subsequent studies of the symbiotic relationship between Rd. prolixus and Rc. rhodnii, while also providing a starting point for the development of biotechnological applications for the control of Rd. prolixus.

Two Gram-stain-positive, aerobic, non-spore-forming, non-motile, irregular rod-shaped actinobacteria, designated as D2-41 and D3-21, were isolated from soil samples collected in a natural cave in Jeju, Republic of Korea. Both of the isolates were shown to share 100 % 16S rRNA sequence identity. The cell wall contained -diaminopimelic acid, arabinose and galactose.

Kissing bugs (Hempitera: Reduviidae) are obligately and exclusively blood feeding insects. Vertebrate blood is thought to provide insufficient B vitamins to insects, which rely on symbiotic relationships with bacteria that provision these nutrients. Kissing bugs harbour environmentally acquired bacteria in their gut lumen, without which they are unable to develop to adulthood.

Chagas disease is a human infectious disease caused by and can be transmitted by triatomine vectors, such as . One limiting factor for development is the composition of the bacterial gut microbiota in the triatomine. Herein, we analyzed the humoral immune responses of nymphs treated with antibiotics and subsequently recolonized with either or .

Cortisone is a steroid widely used as an anti-inflammatory drug able to suppress the immune system, thus reducing inflammation and attendant pain and swelling at the site of an injury. Due to its numerous side effects, especially in prolonged and high-dose therapies, the development of the pharmaceutical industry is currently aimed at finding new compounds with similar activities but with minor or no side effects. Biotransformations are an important methodology towards more sustainable industrial processes, according to the principles of "green chemistry".

the causative agent of Chagas disease, colonizes the gut of triatomine insects, including . It is believed that this colonization upsets the microbiota that are normally present, presumably switching the environment to one more favorable for parasite survival. It was previously thought that one particular bacterium, , was essential for insect survival due to its ability to produce vital B-complex vitamins.
