CASSA VA MEAL YBUGS/SOIL BACTERIAl STRUCTURE OF MEALY BUGS Mealy bug is important pest insect of cassava, could destroy plant by suck to eat the nutrient from every the part of the plant were depressed plant dies. The control cassava mealy bugs by soil bacteria have tendency economical and sustainable methods. From the study of structures and chemical components of cassava mealy bugs that could serve as nutrients of bacteria and the possibility of using selected isolates of soil bacteria for destroying structures of cassava mealy bug, that destroy the plant in Northeastern Thailand. Found species, pink mealy bug (Phenacoccus manihoti Matile-Ferrero) higher than three species, green mealy bug (Phenacoccus maderiensis Green), jack beard mealy bug (Pseudococcus jackbeardsleyi Gimpel & Miller), and striped mealy bug (Ferrisia virgata Cockerel). Pink mealy bugs were studied, have cuticle layer size, 3-4 urn. Found the structure of open pores can destroy by using soil bacteria such as anterior and posterior pores (ostioles), several pores for producing wax filament, abdomen pores (circulus) and respiration pores (spiracles) have diameter 2-59,2-7, 17-20, and 9-30 urn, respectively. Chemical compositions of the body of mealy bug found total carbon, total nitrogen, and moisture content 46.35, 6.74, and 77.30% by dry basis, respectively. A total of 416 bacterial isolates from soil samples were collected and screened by morphological characteristic, producing protease lipase and chitinase enzymes, and can grow in cassava mealy bug broth. Eight isolates ofPCSMA53, CCSMA59, SSTBA15, SSTBA16, SSSMA5, SSTBA26, IV KBSMA65, and KSSMA80, after sprayed 2 ml of bacterial suspension (108 cells/ml) with 0.85% normal saline on third instar stages of forty cassava mealy bug feed on peak of cassava stem, the area 16 square centimeter and compared with in soil, the area 50 square centimeter, 70 humidity at 25-28 °C for 5 days (triplicate test).

Here, we present the first molecular identification of bacteriocyte-associated symbionts in these plant sap-sucking insects. Three geographically distant populations of members of the Adelges nordmannianae/piceae complex, identified based on coI and ef1alpha gene sequences, were investigated. Electron and light microscopy revealed two morphologically different endosymbionts, coccoid or polymorphic, which are located in distinct bacteriocytes. Phylogenetic analyses of their 16S and 23S rRNA gene sequences assigned both symbionts to novel lineages within the Gammaproteobacteria sharing o92% 16S rRNA sequence similarity with each other and showing no close relationship with known symbionts of insects. Their identity and intracellular location were confirmed by fluorescence in situ hybridization, and the names ‘Candidatus Steffania adelgidicola’ and ‘Candidatus Ecksteinia adelgidicola’ are proposed for tentative classification.

  • Review on Chromobacterium Violaceum, a Rare but Fatal Bacteria Needs Special Clinical Attention
    REVIEW ARTICLE Review on Chromobacterium Violaceum, a Rare but Fatal Bacteria Needs Special Clinical Attention *S Sharmin1, SMM Kamal2 ABSTRACT Chromobacterium violaceum is isolated from soil and water in tropical and subtropical areas. This Gram negative, capsulated, motile bacillus is considered as a saprophyte but occasionally it can act as an opportunistic pathogen for animals and human. It causes skin lesion with liver and lung abscesses, pneumonia, gastrointestinal tract infections, urinary tract infections, osteomyelitis, meningitis, peritonitis, endocarditis, respiratory distress syndrome and septic shock. Increasing reported cases with Chrombacterium violaceum infection has been noticed in recent decades. It should be considered for its difficult-to-treat entity characterized by a high frequency of sepsis, distantant metastasis, multidrug- resistance and relapse. High mortality rate associated with this infection necessitate prompt diagnosis and appropriate antimicrobial therapy. Key Words: Chromobacterium Violaceum, saprophyte, opportunistic, multidrug-resistance. Introduction Chromobacterium violaceum belongs to the family Although non-pigmented strains have also been Neisseriacea of β-Proteobacteria and was first reported.8 Though not essential for growth and described by Bergonzini in 1880.1 It is a Gram survival, violacein has been suggested to be a negative, heterotrophic, flagellated bacilli which respiratory pigment, having antiparasitic, antibiotic, lives in a variety of ecosystems in tropical and antiviral, immunomodulatory, analgesic, antipyretic subtropical regions.2 C. violaceum is a facultative and anticancer effects. It has no association with anaerobe which is oxidase and catalase positive. It pathogenesis.9, 10 grows optimally at 30-350C. It is a saprophyte found Although C. violaceum has been recognized as the mainly in soil and water.

Lyons1,4 Abstract In the coming years and decades, advanced space- and ground-based observatories will allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially habitable exoplanets for signatures of life. Life on Earth, through its gaseous products and reflectance and scattering properties, has left its fingerprint on the spectrum of our planet. Aided by the universality of the laws of physics and chemistry, we turn to Earth’s biosphere, both in the present and through geologic time, for analog signatures that will aid in the search for life elsewhere. Considering the insights gained from modern and ancient Earth, and the broader array of hypothetical exoplanet possibilities, we have compiled a comprehensive overview of our current understanding of potential exoplanet biosignatures, including gaseous, surface, and temporal biosignatures. We additionally survey biogenic spectral features that are well known in the specialist literature but have not yet been robustly vetted in the context of exoplanet biosignatures.

NIALL A. LOGAN Department of Biological Sciences, Glasgow College of Technology, Cowcaddens Road, Glasgow G4 OBA, Scotland Received 17 January 19891Accepted 31 July 1989 A total of 113 violet chromogens, 45 of which produced spreading colonies characteristic of Chromobacterium fluviatile, were isolated from fresh water. These isolates and 27 other chromobacteria, 9 duplicates, and 11 reference strains were subjected to 95 characterization tests, and similarities were computed by using the coefficient of Gower. Cluster and principal coordinate analyses showed Janthinobacterium lividurn to be a heterogeneous species but Chromobacterium violaceum and C.fluvitatile to be well-separated and homogeneous phenons. The new, monospecific genus Zodobacter is proposed to accommodate C. fluviatiZe, which was originally placed in the genus Chromobacterium, despite its low guanine-plus-cytosine content (50 to 52 mol%, but 65 to 68 mol% for C. violaceum), pending the study of further isolates.

Abstract: Chromobacterium violaceum, a gram-negative, facultative anaerobic, non-sporing coccobacillus, producing a natural antibiotic called violacein was extracted from Chromobacterium violaceum MTCC 2656, collection of Chandigarh. The present study reports different types of microbial population along with Chromobacterium violaceum in 36 samples of spoiled vegetables. In the numerous microbial populations, three different strains (HMCCC 45, HMCCC 46 and HMCCC 47) were isolated and subjected to various morphological and biochemical tests. The results reveal that the three strains isolated, HMCCC 46 was similar to the standard except that HMCCC 46 colonies were dark violet in colour. The antibiotic sensitivity test of HMCCC 46 revealed that it was resistant to vancomycin, ampicillin, linezolid, and susceptible to colistin, oxacillin, gentamicin, norfloxacin, chloramphenicol, amikacin.

Although many groups in the world are working with this bacterium, very few reviews have been written in the last 40 years.39,45,69 ABSTRACT: Violet-pigmented bacteria, which have been described since the end of the 19th century, are occasionally the causative agent of septicemia and sometimes cause fatal infection in human and animals. Bacteria, producing violet colonies due to the production of a nondiffus- ible pigment violacein, were classified as a redefined genus Chromobacterium. Chromobacte- rium violaceum is Gram-negative, and saprophyte from soil and water is normally considered nonpathogenic to human, but is an opportunistic pathogen of extreme virulence for human and animals. The biosynthesis and biological activities of violacein and the diverse effects of this pigment have been studied. Besides violacein, C. violaceum produces other antibiotics, such as aerocyanidin and aerocavin, which exhibit in vitro activity against both Gram-negative and Gram-positive bacteria.

  • Bacteria Associated with Cockroaches: Health Risk Or Biotechnological Opportunity?
    Applied Microbiology and Biotechnology (2020) 104:10369–10387 https://doi.org/10.1007/s00253-020-10973-6 MINI-REVIEW Bacteria associated with cockroaches: health risk or biotechnological opportunity? Juan Guzman1 & Andreas Vilcinskas1,2 Received: 2 June 2020 /Revised: 14 October 2020 /Accepted: 21 October 2020 / Published online: 31 October 2020 # The Author(s) 2020 Abstract Cockroaches have existed for 300 million years and more than 4600 extant species have been described. Throughout their evolution, cockroaches have been associated with bacteria, and today Blattabacterium species flourish within specialized bacteriocytes, recycling nitrogen from host waste products. Cockroaches can disseminate potentially pathogenic bacteria via feces and other deposits, particularly members of the family Enterobacteriaceae, but also Staphylococcus and Mycobacterium species, and thus, they should be cleared from sites where hygiene is essential, such as hospitals and kitchens. On the other hand, cockroaches also carry bacteria that may produce metabolites or proteins with potential industrial applications. For example, an antibiotic-producing Streptomyces strain was isolated from the gut of the American cockroach Periplaneta americana. Other cockroach-associated bacteria, including but not limited to Bacillus, Enterococcus,andPseudomonas species, can also produce bioactive metabolites that may be suitable for development as pharmaceuticals or plant protection products. Enzymes that degrade industrially relevant substrates, or that convert biomasses into useful chemical precursors, are also expressed in cockroach-derived bac- teria and could be deployed for use in the food/feed, paper, oil, or cosmetics industries. The analysis of cockroach gut microbiomes has revealed a number of lesser-studied bacteria that may form the basis of novel taxonomic groups.

Cell density is detected through the production and diffusion of acyl-homoserine lactones (AHLs). The AHL concentration increases until threshold is reached, and AHLs bind the AHL receptor causing transcription of QS-controlled genes. Many QS-controlled genes include: antimicrobials, biofilm components, and other virulence factors. For this reason, we believe that QS is critical for survival during competition with other bacteria. To test our hypothesis, we have developed a competition model between two soil-saprophytes, Burkholderia thailandensis and Chromobacterium violaceum. Our research demonstrates that QS in C. violaceum and B. thailandensis controls the production of antimicrobials that inhibit the other species’ growth. C. violaceum using QS to increase resistance to bactobolin, a B.

A current grand challenge in the microbiome field is 33 to identify factors produced by normal microbiome bacteria that cause these observed 34 health and disease correlations.
