Cationic Polypeptides Contribute To The Anti-Hiv-1 Activity Of Human Seminal Plasma, Julie A. Martellini, Amy L. Cole, Nitya Venkataraman, Gerry A. Quinn, Pavel Svoboda, Bhushan K. Gangrade, Jan Pohl, Ole E. Sorensen, Alexander M. Cole

Public Health Resources

Mucosal surfaces of the reproductive tract as well as their secretions have important roles in preventing sexual transmission of HIV-1. In the current study, the majority of the intrinsic anti-HIV-1 activity of human seminal plasma (SP) was determined to reside in the cationic polypeptide fraction. Antiviral assays utilizing luciferase reporter cells and lymphocytic cells revealed the ability of whole SP to prevent HIV-1 infection, even when SP was diluted 3200-fold. Subsequent fractionation by continuous flow acid-urea (AU)- PAGE and antiviral testing revealed that cationic polypeptides within SP were responsible for the majority of anti-HIV-1 activity. A proteomic approach was utilized …

Biological Screening Of Vitis Vinifera L. Leaf Fractions, Di̇dem Deli̇orman Orhan, Ni̇lüfer Orhan, Berri̇n Özçeli̇k, Fatma Ergun

Turkish Journal of Biology

The fractions of different polarity, namely chloroform, ethylacetate, n-butanol, and remaining water fractions, were fractionated from an aqueous extract of V. vinifera leaves. The antibacterial, antifungal, antiviral, antioxidant activities, and total phenolic content of these fractions were investigated. The chloroform fraction showed a promising effect against Herpes simplex virus type-1 (HSV-1) and Parainfluenza viruses (PIV). The results indicated that all the fractions were more pronounced against gram-positive bacteria (S. aureus and E. faecalis) than against gram-negative bacteria (E. coli and P. aeruginosa). On the other hand, the fractions showed equal antifungal activity against the genus Candida (C. albicans and C. …

The Chemical Ecology Of Antarctic Sponges, Kevin J. Peters Jan 2009

The Chemical Ecology Of Antarctic Sponges, Kevin J. Peters

All ETDs from UAB

Sponges were collected from shallow waters along the western Antarctic Peninsula near Palmer Station on Anvers Island. The majority (78%) of the sponges were found to have outer tissues defended against the omnivorous, Antarctic sea star Odontaster validus. Of the species that had outer tissues defended, 62% of them also had internal tissues that inhibited feeding by O. validus. Lipophilic or hydrophilic extracts coated on artificial food pellets were found to be unpalatable for all of the sponge species tested. These data provide evidence that defenses are common survival strategies in sessile macroinvertebrates from Antarctica but that the allocation of …

Food Colloids As Carrier Systems For Antimicrobials, Sarisa Suriyarak Jan 2008

Food Colloids As Carrier Systems For Antimicrobials, Sarisa Suriyarak

Masters Theses 1911 - February 2014

Colloidal dispersions such as oil-in-water or water-in-oil emulsions have found widespread use in the food industry. Oil-in-water emulsions consist of three principal components i.e. oil dispersed in the form of droplets, water surrounding the droplets as the continuous phase, and emulsifiers comprising the interface. Because of the complicated interaction among components, it is often difficult to predict the physicochemical properties and final functionalities of emulsions. Nevertheless, the structural and functional features of emulsions allow scientists to create many unique emulsions that may serve as suitable carriers for lipophilic functional compounds. These functional compounds may include antioxidants, flavors, colors and antimicrobials, …

Regulation Of The Lactoperoxidase System In The Airway, Miryam A. Fragoso Dec 2007

Regulation Of The Lactoperoxidase System In The Airway, Miryam A. Fragoso

Open Access Dissertations

The lactoperoxidase (LPO) antimicrobial system has been shown to play an important role in maintaining sterile conditions in several tissues including the mammary gland, the salivary gland, and the airway. The LPO system in the airway consists of the enzyme LPO and its substrates hydrogen peroxide and an anion. LPO catalyzes the oxidation of a halide or pseudohalide ion for example SCN-or I- by hydrogen peroxide producing a product, OSCN- or OI- which have antibacterial, antifungal, and antiviral properties. In order to have a functional antimicrobial system all the components need to be present at appropriate concentrations. The LPO system …

The Antibacterial Properties Of Brookite Phase Titanium Dioxide Nanoparticles Against Methicillin-Resistant Staphylococcus Aureus, Rupal Shah Aug 2007

The Antibacterial Properties Of Brookite Phase Titanium Dioxide Nanoparticles Against Methicillin-Resistant Staphylococcus Aureus, Rupal Shah

All Theses

Staphylococcus aureus (S. aureus), a major human pathogen, is a common cause of infections worldwide due to its high virulence intensity. By adapting to rapidly changing and uniformly hostile environments, strains of S. aureus acquire resistance to antimicrobial agents shortly after their exposure. For example, within a year of its introduction, S. aureus developed resistance to methicillin which triggered the development of other antimicrobial treatments. In spite of the various antibiotics currently used to treat methicillin-resistant S. aureus (MRSA) infections, antimicrobial resistance is an unavoidable consequence due to the selective pressure of antibiotic exposure. Thus, other prevention modalities are warranted …

Colloidal Particles As Antimicrobial Carrier Systems, Dustin W. Carnahan Jan 2007

Colloidal Particles As Antimicrobial Carrier Systems, Dustin W. Carnahan

Masters Theses 1911 - February 2014

The objective of this thesis is to develop a method by which antimicrobials are delivered into a food product as a concentrated dose to the specific area in which the microorganism is growing without interference from the food matrix. More specifically, we plan to achieve this by delivering the antimicrobials nisin and lysozyme attached to nanoparticles and emulsion droplets. We hypothesize that (a) the attachment to a delivery vessel may increase the local concentration of the antimicrobial in the vicinity of the bacterial pathogens and (b) that the size and charge of the nanoparticle following attachment of the antimicrobials will …

Evaluating The Effect Of Two Commercial Antimicrobial Products On Salmonella Spp. In The Aquatic Habitat Of The Red-Eared Slider Turtle (Trachemys Scripta Elegans), Trevor Theadore Zachariah

LSU Master's Theses

Turtle-associated salmonellosis was recognized as a public health concern in the 1960’s, particularly due to an increase in the incidence of disease among children. In response to the public health threat, the United States Food and Drug Administration (FDA) implemented regulations in 1975 restricting the sale of turtle eggs and turtles with a carapace length less than 10.2 cm. Since that time, attempts to eliminate Salmonella from turtles using antibiotics have been unsuccessful and lead to antibiotic resistant strains of Salmonella on turtle farms. Recent work has focused on identifying non-antibiotic products to suppress or eliminate Salmonella and reverse the …

Antimicrobial Properties Of Syringopeptin 25a And Rhamnolipids, Prerak T. Desai May 2006

Antimicrobial Properties Of Syringopeptin 25a And Rhamnolipids, Prerak T. Desai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increasing bacterial resistance to available antibiotics requires the search for new antibacterial compounds to be broadened. This study investigated the antimicrobial properties of two secondary metabolites from fluorescent pseudomonads -- syringopeptin 25A, a lipodepsipeptide produced by Pseudomonas syringae pv. syringae, and a rhamnolipid mixture produced by Pseudomonas aeruginosa. The rate of antimicrobial action was determined by monitoring the rate of uptake of propidium iodide during exposure to the compounds. Inhibition was also confirmed by the microbroth dilution method to determine the MI Cs. Both the compounds inhibited growth of Gram-positive organisms, including Mycobacterium smegmatis, staphylococci, and …

Antimicrobial Effect Of Cetylpyridinium Chloride Against Listeria Monocytogenes Growth On The Surface Of Raw And Cooked Shrimp, Tracie Michelle Dupard Jan 2005

Antimicrobial Effect Of Cetylpyridinium Chloride Against Listeria Monocytogenes Growth On The Surface Of Raw And Cooked Shrimp, Tracie Michelle Dupard

LSU Master's Theses

Listeria monocytogenes has emerged as a major foodborne pathogen for the seafood industry due to its psychrotrophic nature and its ubiquitous presence. It has been isolated from soil, sewage, dead vegetative matter, aquatic environments, fecal material, fish, crustaceans, and domesticated animals. As a result, L. monocytogenes has been responsible for several shrimp recalls and has been epidemiologically linked to human listeriosis. Fresh seafood products are highly perishable and their shelf-life is limited by microbiological spoilage. Therefore, when pathogenic microorganisms are involved, it poses a health threat to the general public. The situation is further complicated because seafood processing plants are …

Characterization Of Microorganisms From The Deep Subsurface That Produce Antimicrobial Substances, Michael Victor Staudaher Jan 1996

Characterization Of Microorganisms From The Deep Subsurface That Produce Antimicrobial Substances, Michael Victor Staudaher

UNLV Retrospective Theses & Dissertations

A group of 95 actinomycete-like bacterial isolates were obtained from the deep subsurface at the Nevada Test Site. These isolates were screened for the ability to inhibit the growth of selected challenge organisms. A subset of 12 isolates were found to produce antibacterial substances during their growth and were termed bioactive. It was hypothesized that because the isolation source was solid rock, some of the bioactive isolates would require the presence of a surface in order to make antibiotic substances, and that some of these isolates would fail to produce antibiotics when grown in broth culture alone. It was further …

G85-748 Prevention And Control Of Swine Dysentery, Gerald E. Duhamel, Alex Hogg, Barbara E. Straw Jan 1985

G85-748 Prevention And Control Of Swine Dysentery, Gerald E. Duhamel, Alex Hogg, Barbara E. Straw

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the causes and symptoms of swine dysentery and offers management recommendations and treatment procedures for its prevention and control.

Swine dysentery is a highly contagious disease of growing and finishing pigs. First described in Indiana in 1921, it has been called black scours, bloody scours, and vibrionic dysentery.

Swine dysentery causes important financial losses because of reduced feed efficiency and lower weight gain, costs of medication and additional animal care, and death. Substantial costs may result from loss of sales of breeding stock, or depopulation when necessary. Serpula (Treponema) hyodysenteriae, a spiral bacterium, is the cause …
