Abstract:
The current study was conducted to determine the inhibitory effect of the aqueous extract of hornwort Ceratophyllum demersum on Vibrio cholerae bacteria that affects the common carp Cyprinus carpio L. in fish farms. The inhibitory effect of the aqueous extract was determined in petri dishes. The inhibition effects of the extract and six common antibiotics (Nalidixic acid, Nitrofurantoin, Gentamicin, Streptomycin, Tetracycline, and Amoxicillin) were compared; the results showed that the inhibition effect of the aqueous extract of hornwort was higher than the inhibitory effects of the six antibiotics. The stock solution 100% of the aqueous extract showed an inhibition effect reached 35.3 mm compared with 25 mm, 15 mm, 7 mm, 10 mm, 23 mm and 11 mm of Nalidixic acid, Nitrofurantoin, Gentamicin, Streptomycin, Tetracycline, and Amoxicillin antibiotics respectively. A positive correlation was recorded between concentration of aqueous extract and its inhibitory effect. The average of inhibition diameter was 23.3 mm, 27.6 mm, 28.6 mm, and 35.3 mm for the concentrations 25%, 50%, 75% and 100% of the stock solution, respectively.

Abstract:
Antimicrobial peptides (AMPs) recognized as host defense peptide (HDPs), have achieved considerable attention during last two decades as potential components of the instinctive immune system. Amongst the insects over casted for AMPS the hymenopterans comprising of ants have been identified for possessing potent antimicrobial peptides, those are small linear peptides. An investigation was taken up to screen for antimicrobial peptides collected from ants thriving in Forest Plantation in Hijli of Midnapore District, W.B. Three species of ants, members of the family Formicidae, were collected for in vitro antimicrobial activities of the whole body extract. These were tested by in the 10% of acetic acid solution using the Kirby-Bauer disc diffusion method against test microorganism viz. Escherichia coli, Staphylococcus mutans, Vibrio cholarae and Candida albicans. A strong antimicrobial activity was noted in all the extracts against all the microorganisms. The Spectrophotometric scanning was carried out to confirm the presence of peptides. TLC and HPLC were done. The result revealed that all the three species of ants exploited in this study were found to be a promising source of antimicrobial peptides.

Abstract:
Microorganisms are ubiquitous and their impact could be appreciated directly or indirectly. This study was aimed at determining the occurrence of pathogenic bacteria on the phylloplane of some medicinal plants commonly used to treat diseases by oral administration. Leaves samples were collected aseptically from Cassia fistula (Cassia) Mangifera indica (Mango) and Psidium guajavum (Guava) and their bacterial contents were assessed. Higher bacterial counts were observed in raw samples followed by those washed with sterile water. Samples washed with sterile warm water (blanched) were shown to have lower counts although without statistical significance (p ≤ 0.05). Guava leaves had higher counts (3.4×106 cfu/g) in the raw samples and cassia in blanched (6.4×105 cfu/g). However, mango leaves had the lowest (8.4×105 cfu/g and 2.0×105 cfu/g) in both the treatments respectively. Twenty bacterial species were isolated comprising Gram negative and Gram positive species. Bacterial identification revealed that Proteus mirabilis (35%), Proteus vulgaris (15%), Escherichia coli (15%), Klebsiella pneumoniae (5%), Morganella morganii (5%), Salmonella typhi (10%), Enterobacter sp. (5%), Staphylococcus aureus (5%) and Vibrio cholarae (5%) were the prevalent species. These organisms could be potential pathogens and proper washing with hot water may serve a better means of reducing the microbial contents and thus, it is recommended.

Abstract:
ABSTRACT Enteric pathogens have developed several resistance mechanisms to survive the antimicrobial action of bile. We investigated the transcriptional profile of Vibrio cholerae O1 El Tor strain C6706 under virulence gene-inducing conditions in the presence and absence of bile. Microarray analysis revealed that the expression of 119 genes was affected by bile. The mRNA levels of genes encoding proteins involved in transport were increased in the presence of bile, whereas the mRNA levels of genes encoding proteins involved in pathogenesis and chemotaxis were decreased. This study identified genes encoding transcriptional regulators from the TetR family (vexR and breR) and multidrug efflux pumps from the resistance-nodulation-cell division superfamily (vexB and vexD [herein renamed breB]) that were induced in response to bile. Further analysis regarding vexAB and breAB expression in the presence of various antimicrobial compounds established that vexAB was induced in the presence of bile, sodium dodecyl sulfate, or novobiocin and that the induction of breAB was specific to bile. BreR is a direct repressor of the breAB promoter and is able to regulate its own expression, as demonstrated by transcriptional and electrophoretic mobility shift assays (EMSA). The expression of breR and breAB is induced in the presence of the bile salts cholate, deoxycholate, and chenodeoxycholate, and EMSA showed that deoxycholate is able to abolish the formation of BreR-P breR complexes. We propose that deoxycholate is able to interact with BreR and induce a conformational change that interferes with the DNA binding ability of BreR, resulting in breAB and breR expression. These results provide new insight into a transcriptional regulator and a transport system that likely play essential roles in the ability of V. cholerae to resist the action of bile in the host.

Abstract:
Two disease regions existed on the Oregon Trail. Asiatic cholera impacted the Platte River flood plain from 1849 to 1852. Dysentery developed two endemic foci due to the decay of buffalo carcasses in eastern and middle Nebraska between 1844 and 1848, but later developed a much larger endemic region west of this Great Plains due to the infection of livestock carcasses by opportunistic bacteria. This study demonstrates that whereas Asiatic cholera diffusion along the Trail was defined primarily by human population features, topography, and regional climate along the Platte River flood plain, the distribution of opportunistic dysentery along the Trail was defined primarily by human and animal fitness in relation to local topography features. By utilizing a geographic interpretation of disease spread, the Asiatic cholera epidemic caused by Vibrio cholerae could be distinguished from the dysentery epidemic caused by one or more species of Salmonella or Campylobacter. In addition, this study also clarifies an important discrepancy popular to the Oregon Trail history literature. "Mountain fever," a disease typically associated with Rocky Mountain Spotted Fever, was demonstrated to be cases of fever induced by the same bacteria responsible for opportunistic dysentery. In addition, several important geographic methods of disease interpretations were used for this study. By relating the epidemiological transition model of disease patterns to the early twentieth century sequent occupance models described in numerous geography journals, a spatially- and temporally-oriented disease model was produced applicable to reviews of disease history, a method of analysis which has important applications to current studies of disease patterns in rapidly changing rural and urban population settings.
