The present study aimed to use enterobacterial repetitive intergenic consensus (ERIC) fingerprints to design SCAR primers for the detection of Escherichia coli. The E. coli strains were isolated from various water sources. The primary presumptive identification of E. coli was achieved using MacConkey agar. Nineteen isolates were selected and confirmed to be(More)
The entomopathogenic fungus Cod-MK1201 was isolated from a dead cicada nymph. Three regions of ribosomal nuclear DNA, the internal transcribed spacers of nuclear ribosomal DNA repeats (ITS), the partial small subunit of rDNA (nrSSU) , and the partial large subunit of rDNA (nrLSU), and two protein-coding regions, the elongation factor 1α (EF-1α), and the(More)
Problem statement: The genetic diversity of Barbodes species in Thailand is presently unavailable. The objectives of this study were to study external morphology and genetic diversity using Randomly Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) of three Barbodes species; Barbodes altus, B. gonionotus and Barbodes sp. Approach: Two of twelve(More)
The literature on the entomopathogenic fungi in the genus Cordyceps describing its use in the agricultural area as a biocontrol agent is limited. In this study, a total of 47 isolates of entomopathogenic fungi were isolated from dead cicada nymphs obtained from various locations in the northeast of Thailand. These isolates were primarily screened for(More)
The known phenanthrenone trigonostemone (1), along with a new phenanthrenone, 9-O-demethyltrigonostemone (2), and two new phenanthropolones, 3,6,9-trimethoxyphenanthropolone (3) and 4,6,9-trimethoxyphenanthropolone (4), were isolated from the roots of Strophioblachia fimbricalyx. Compound 2 showed cytotoxicity against NCI-H187, KB, and MCF7 cancer cells(More)
The entomopathogenic fungus Polycephalomyces nipponicus is known to have activity against human pathogenic bacteria and the malaria pathogen; however, information about its genetic variation is limited. In this study, cicada nymphs infected with entomopathogenic fungi were collected from various locations in the northeast of Thailand. Internal transcribed(More)
Prolonged exposure to dexamethasone (DEX), a synthetic glucocorticoid receptor agonist, has been shown to induce neuronal cell death in the hippocampus. Cell death is particularly pronounced in the CA3 pyramidal neurons, inducing cognitive dysfunction. The aim of this study was to investigate the effect of melatonin on hippocampal CA3 pyramidal cells in(More)
Actinobacteria from the genus Streptomyces have been studied as potential biocontrol agents worldwide. In this study, a total of 35 isolates of Actinomycete like colonies were isolated from the rhizospheres of various plant species. These isolates were primary screened for antagonistic activity to inhibit mycelial growth of Colletotrichum gloeosporioides.(More)
This study aimed to identify a suitable organic solvent for extracting bioactive compounds from Polycephalomyces nipponicus and to evaluate the antibacterial and anticancer activities of the extracts obtained. Only extracts obtained with ethyl acetate exhibited antibacterial activity, so ethyl acetate was chosen for large-scale extraction. The minimum(More)
