TL;DR: The in vitro antibacterial activity of the essential oils was studied against 12 bacteria strains using disc diffusion and broth microdilution methods and exhibited strong zone of inhibitions against some bacteria such as S. faecalis and S. macrcescens.
Abstract: The chemical composition and the antibacterial activity of the essential oils obtained by hydrodistillation from the leaves of Callistemon citrinus and Callistemon viminalis were analyzed by GC and GC/MS. Twenty-four and twelve components were identified for C. citrinus and C. viminalis, representing 92.0% and 98.3% of the total oils. The major components of C. citrinus and C. viminalis were 1,8-cineole (61.2% and 83.2%) and α-pinene (13.4% and 6.4%), respectively. The in vitro antibacterial activity of the essential oils was studied against 12 bacteria strains using disc diffusion and broth microdilution methods. The oils exhibited strong zone of inhibitions against some bacteria such as S. faecalis (20.3-24.0 mm), both strains of S. aureus (23.0-26.3 mm), B. cereus (17.3-19.0 mm) and S. macrcesens (11.3-23.7 mm) when compared to standard antibiotics gentamycin and tetracycline used as controls. Expect for P. aeruginosa and S. macrcescens, the MIC values of both essential oils ranged from 0.31-2.50 mg/mL.

TL;DR: A new species of gall midge found feeding within vegetative buds of Callistemon viminalis plants grown in a production greenhouse in Victoria, Australia is described and named Dasineura callistemoni Kolesik sp.
Abstract: Callistemon (Myrtaceae) is a plant genus native to Australia with many cultivars grown as ornamentals worldwide. Several orange larvae of an undescribed gall midge (Diptera: Cecidomyiidae) were found feeding within vegetative buds of Callistemon viminalis plants grown in a production greenhouse in Victoria, Australia. Infested buds stopped their development and, following the departure of larvae, turned necrotic. Pupation took place in the soil. Young potted plants were infested and severely retarded in their overall growth. The new species is described and named Dasineura callistemoni Kolesik sp. nov.

TL;DR: The thin waxy coatings on leaves of nine species of Callistemon, two of Melaleuca and one species of Metrosideros, have been studied for the occurrence of leaf surface flavonoids and the new natural C-methyl flavonol, 5,7-dihydroxy-3,8,4'-trimethoxy-6-C-methylflavone, was isolated from Metrosiders robusta.

TL;DR: Callistemon citrinus appears to be a potent anti microbial agents that could be considered as a medicinal plant that has antiseptic effects and could be use d as a therapeutic agent.
Abstract: Problem statement: Callistemon citrinus and Albizia lebbeck are two kind of native plants in Khoozestan province in Iran, according to the agree ment that medicinal plant could be replaced the medicine we are trying to determine the antibacteri al effect of the named plants. Approach: The antibacterial properties of ethanolic and methanoli c extract of Callistemon citrinus leaf and Albizia lebbeck leaf was studied against different pathogenic bac teria including Streptococcus pyogenes , Bacillus cereus , Bacillus anthracis , Salmonella typhi , Kelebsiella pneumoniae , Streptococcus epidermidis , Escherichia coli , Pseudomonas aeruginosa and Listeria monocytogenes by disc diffusion method. The samples collected fro m young trees from Ahvaz city at may 2009. Results: The extract of C. citrinus showed significant activity against the majority o f bacteria which is comparable with standard antibiotics. Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) for hydroalcoholic extract of Callistemon have been determined also for four bacteria; S. pyogenesis , S. typhy , B. anthrasis , S. typhy , Albizia lebbeck extract despite previous reports didn't have any significant effect . Conclusion: According to the good effects of Callistemon citrinus on Bacillus species it has antiseptic effects and could be use d as a therapeutic agent and therefore, it appears to be a potent anti microbial agents that could be considered as a medicinal plant.
