This study was an attempt to isolate E. sakazakii from different food and environmental sources so as to establish its presence and possible source of transmission. For this, 93 samples (i.e., 37 from dairy and 56 from non-dairy) were collected using standard procedures of sampling. Out of these samples, 45 isolates (i.e., 14 from dairy and 31 from other samples) were taken further on the basis of growth on tryptic soy agar. On further screening on the basis of Gram staining, catalase and oxidase test, only 27 isolates were observed to be positive. The positive isolates were also subjected to PCR based identification using species specific primers. Overall, 11 isolates confirmed E.as sakazakii were also tested for virulent characteristics (i.e., hemolytic activity, haemagglutination test and DNase production) and all the isolates were found to be positive showing a potential threat of infection through food commodities. Keywords: Enterobacter sakazakii; Cronobacter; Virulence lactoferrin showed some effect by reducing the viability of C. -

Phylogenetics of Buchnera Aphidicola Munson Et Al., 1991

Buchnera aphidicola genes detected in seven aphid species, collected in 2017 from different plants and altitudes in Adana Province, Turkey were analyzed to reveal phylogenetic interactions between Buchnera and aphids. The 16S rRNA gene was amplified and sequenced for this purpose and a phylogenetic tree built up by the neighbor-joining method. A significant correlation between B. aphidicola genes and the aphid species was revealed by this phylogenetic tree and the haplotype network. Specimens collected in Feke from Solanum melongena L. was distinguished from the other B. aphidicola genes on Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) with a high bootstrap value of 99. Buchnera aphidicola in Myzus spp. was differentiated from others, and the difference between Myzus cerasi (Fabricius, 1775) and Myzus persicae (Sulzer, 1776) was clear. Although, B. aphidicola is specific to its host aphid, certain nucleotide differences obtained within the species could enable specification to geographic region or host plant in the future.

The Coliform Kind: E. coli and Its “Cousins” The Good, the Bad, and the Deadly by Dr. Alan L. Gillen and Matthew Augusta on October 3, 2018 Abstract Even though some intestinal bacteria strains are pathogenic and even deadly, most coliforms strains still show evidence of being one of God’s “very good” creations. In fact, bacteria serve an intrinsic role in the colon of the human body. These bacteria aid in the early development of the immune system and stimulate up to 80% of immune cells in adults. In addition, digestive enzymes, Vitamins K and B12, are produced byEscherichia coli and other coliforms. E. coli is the best-known bacteria that is classified as coliforms. The term “coliform” name was historically attributed due to the “Bacillus coli-like” forms. -

Ltd., Chinar Fortune City, Hoshangabad Rd., Madhya Pradesh, India Abstract Citrobacter braakii (C. braakii) is widespread in nature, mainly found in human urinary tract. The current study was attempted to investigate the effect of Mr. Trivedi’s biofield treatment on C. braakii in lyophilized as well as revived state for antimicrobial susceptibility pattern, biochemical characteristics, and biotype number. Lyophilized vial of ATCC strain of C. braakii was divided into two parts, Group (Gr.) I: control and Gr. II: treated. Gr. II was further subdivided into two parts, Gr. IIA and Gr. IIB. Gr. IIA was analysed on day 10 while Gr. IIB was stored and analysed on day 159 (Study I). After retreatment on day 159, the sample (Study II) was divided into three separate tubes. First, second and third tube was analysed on day 5, 10 and 15, respectively. All experimental parameters were studied using automated MicroScan Walk-Away® system. The 16S rDNA sequencing of lyophilized treated sample was carried out to correlate the phylogenetic relationship of C. -

Prevalence of Antibiotic-Resistant, Toxic Metal-Tolerant and Biofilm- Forming Bacteria in Hospital Surroundings

The present study aims to assess the co-selection of antibiotic resistance and heavy metal tolerance by bacteria isolated from hospital effluents. These isolates were also tested for hemolytic activity, pH-tolerance, thermal inactivation, auto- aggregation, cell-surface hydrophobicity and interaction with other bacteria. The study reports the prevalence of antibiotic-resistant and heavy metal tolerant bacteria in clinical effluents and water samples. Most of these isolates were resistant to vancomycin, clindamycin, ampicillin, rifampicin, penicillin-G, methicillin and cefdinir, and evidenced the production of extended-spectrum β-lactamase enzyme. Toxic metals such as cadmium, copper, iron, lead and zinc also exert a selection pressure towards antibiotic resistance. Pseudomonas aeruginosa strain GCC_19W3, Bacillus sp. strain GCC_19S2 and Achromobacter spanius strain GCC_SB1 showed β-hemolysis, evidenced by the complete breakdown of the red blood cells.
