ABSTRACT The antimicrobial activity of 1-chloro-2,2,5,5-tetramethyl-4-imidazoidinone (MC), a nonbleaching N-halamine compound, was investigated on materials commonly used in broiler production, including stainless steel, galvanized metal, aluminum, plastic, and pressure-treated wood. MC aqueous solutions at 0.02, 0.04, and 0.06% were challenged with Salmonella Typhimurium and Campylobacter jejuni at 6 log CFU/mL, resulting in complete inactivation of both bacteria in 30 min with 0.06% MC. Follow-up experiments were performed using test materials treated with 0.1 and 1% MC and challenged with Salmonella Typhimurium and C. jejuni at 6 log CFU per coupon. Stability of MC on the various surfaces of testing materials was assessed, and the chlorine content of the materials was measured using iodometric thiosulfate titration over a 4-week period. Antimicrobial activities were evaluated by a sandwich test on each sampling day during 4 weeks of storage. On the samples treated with 1% MC, bacteria at 6 log CFU per coupon were completely inactivated within 2 h of contact time. The antimicrobial activity extended to 4 weeks, and the active chlorine atoms in the treated materials decreased from the initial 1016 to 1015 atoms per cm2. Overall, MC had high stability and long-lasting antimicrobial activity, which suggests that MC has high potential for use as a novel antimicrobial agent to lower the microbial load on broiler house materials.

Enhancement Property

Granule contents from rat polymorphonuclear neutrophils were prepared by extraction with 0.2 M acetate buffer (pH 4.0), dialyzed against phosphate-buffered saline (pH 7.0), and tested for bactericidal activity against selected target bacteria. Salmonella typhimurium LT-2 and a series of progressively rough lipopolysaccharide outer membrane mutants derived from it were used to monitor antimicrobial activity. Although an antimicrobial potential was present in rat granule contents for S. typhimurium, the growth of Pseudomonas aeruginosa PAO-1 in antimicrobial assay mixtures containing rat granule contents was substantially enhanced over control values. The growth enhancement property of the granule protein was heat resistant and promoted increased oxygen consumption by whole cells.

Context: Plant based antimicrobial represent a vast untapped source for medicines and further exploration of plant antimicrobial neeto occur. Evolvulus alsinoides (L) (Convolvulaceae) is a perennial herb is used in traditional medicine in East Asia, India, Africa and Philippines to cure fever, cough, cold, venereal diseases, azoospermia, adenitis and dementia.   Objective: The objective of this research was to evaluate the antimicrobial activity of the extracts of E. alsinoides on some clinical microbial isolates.   Materials and Methods: The ed thanolic and aqueous extracts of the whole plant (leaves and twigs) were analysed for alkanoids, tannins, glycosides, steroids, flavonoids, saponins, volatile oil and resins. The determination of antibacterial activity was done using the agar well diffusion technique. Pure cultures of pathogenic bacteria such as Bacillus cereus, Staphylococcus aureus, Micrococcus leutus, Klebsiella Pneumoniae, Pseudomonas aeruginosa, Escherichia coli and Salmonella typhi were used for antibacterial activity assay, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC).   Results: The ethanolic extract of the plant had MIC values ranging from 16 mg/ml to 512.5 mg/ml. The least MIC was 16mg-ml against Salmonella typhi while Bacillus cereus and Staphylococcus aureus showed the highest MIC of 512.5 mg-ml. In the aqueous extract the MIC ranged between 512.5 to >1025 mg/ml. Salmonella typhi, Micrococcus luteus and Staphylococcus aureus were not inhibited by the water extract. Phytochemical result showed ethanol to be a better solvent for the extraction of the bioactive agents in this plant which include: glycosides, alkaloids, saponins, tannins, flavonoids and volatile oil.   Conclusion: In this study the gram-negative organisms had the lowest MICs and MBCs. This suggests their higher susceptibility to the extract of this plant. On the basis of the result obtained in this investigation it can be concluded that ethanol extract of Evolvulus alsinoides had significant in vitro broad spectrum antimicrobial activity.   Keywords: Evolvulus alsinoides; Phytochemical screening; Antibacterial activity.

Comparative study of plant extracts crude and aqueous, methanolic and ethanolic with antibiotics, provide evidence that calotropis procera extracts has the similar antibacterial activity as these antibiotics against test pathogens i.e. Salmonella typhi and E.coli. The analysis of antimicrobial activity of aqueous, methanolic and ethanolic extract of leaves and flower of Calotropis procera was carried out in disc method and also determined MIC value at 600nm through optical density using spectrophotometer. The zone of inhibition produced by extracts was examined and compares it with zone produced by antibiotics. The effect exhibited by ethanolic extract of leaves and flower was significantly greater than the aqueous and methanolic extract of leaves and flower. Crude extracts i.e. latex, leaves, fruit and flower crude extracts. Among them, flower crude extracts shows similar zone of inhibition to test anitibiotics.while in MIC value, we made different concentration of extracts and antibiotics.i.e for crude we made 25%, 50%.75% and 100% concentration of crude juice and for the aqueous, methanolic and ethanolic we made 0.5mg/mL,1mg/mL,2mg/mL,3mg/mL,4mg/mL, 5mg/mL and 6mg/mL in Dimethyl salfoxide, and same antibiotics concentration. Aqueous leaves extracts show MIC at 0.5mg/ml against E.coli while against Salmonella it shows MIC at 1mg/ml... We also determine phytochemical analysis for presences of different compounds in crude extracts. The obtained results provide a support for the use of Calotropis procera, in traditional medicine and suggest its further advance investigation.

This research was conducted bioactivities by using raw fruits of sapodilla sapota (Manilkara zapota) as a drag growth media of Salmonella typhi bacteria causes typhoid fever disease. Salmonella typhi is a species of bacteria that are gram-negative bacilli shaped, facultative, aerobic, moving with a single pertrich. Sapdilla sapota has antimicrobial activity against Salmonella typhi, because it contains a variety of secondary metabolite compounds such as saponins, tannins and flavonoids.  The purpose of this research was to know how efective the raw fruits of sapodilla sapota (Manilkara zapota) against the growth of Salmonella typhi. This is an laboratory research by using diffusion test method. The sample of this research is to extract the fruit of sapodilla sapota (Manilkara zapota) crude. The results of this research, are 35% concentration of extract cannot be formed drag zone (0 mm), but in 40, 45, 50 and 55% of concentration there are had drag zone (9 mm, 13 mm, 13.5 mm, and 18 mm). this can be said that the raw fruit of sapodilla sapota extract can inhibit the growth of Salmonella typhi bacteria can be done, then the next extension to the sufferers of the disease typhus to consume raw fruits of sapodilla sapota so that can reduce the growth of bacteria.

Hygromycin B was extracted with ethyl acetate, which separates organic phase from aqueous phase in the broth culture filtrate, only the aqueous phase showed significant antimicrobial activity by using agar well diffusion technique. At a concentration of 25mg/ml (as crude extract), this phase excreted its activity against the test microorganisms which include; one G(+) bacteria (Staphylococcus aureus), five G(–) bacteria (Pseudomonas aeruginosa , Proteus mirabilis, Escherichia coli , Klebsiella pneumoniae, Salmonella typhi) and one yeast (Saccharomyces  cerevisiae).          After detecting the aminoglycoside hygromycin B by the Thin Layer Chromatography (TLC) method to ensure presence of the antibiotic, same flow rate (Rf) value (0.357) as that of the standard hygromycin B was obtained.          Results of the optimization conditions showed that the highest antimicrobial activity of hygromycin B was obtained at a medium pH of 8 and incubation temperature of 35°C for 10 days. When the toxicity of hygromycin B crude extract under such conditions was examined on mice liver, a mild effects were appeared
