...Joshua French Professor Erika Burgess BI101 25 July 2012 Feral Pigs and the Negative Effects on Humans It is not every day that someone sits down and thoroughly thinks about the food that they consume. For that matter they do not even think about the animals that they touch, to include feral pigs. Feral pigs are, by definition, a pig that is not kept or bred in a holding (www.websters-online-dictionary.org/definitions/Feral+pig). In Eastern North Carolina these feral pigs are causing an uproar and uneasiness about them. The feral pigs are being accused of carrying a nasty bacteria that can be transmitted to humans, through a variety of different ways. Not only can they transmit a nasty bacteria, but also can do damage to farmers’ crops and land that in turn affects the way that the crops are harvested and how the ecosystem changes due to the damage that these feral pigs do. Wild pigs (also known as wild hogs or feral pigs) are an Old World species and are not native to the Americas. The first wild pigs in the United States originated solely from domestic stock brought to North America by early European explorers and settlers. Many years later, Eurasian wild boar were introduced into parts of the United States for hunting purposes. In areas where domestic pigs and Eurasian wild boar were found together in the wild, interbreeding occurred. Today, many hybrid populations exist throughout the wild pig’s range. Pigs were first introduced in the 1500’s to what is now the southeastern...

...Biology Worksheet i 1. Explain the process of pasteurization. Pasteurization is a process of heating a food, usually liquid, to a specific temperature for a definite length of time, and then cooling it immediately. This process slows microbial growth in food. The process was named after its creator, French chemist and microbiologist Louis Pasteur. The first pasteurization test was completed by Louis Pasteur and Claude Bernard on April 20, 1864. The process was originally conceived as a way of preventing wine and beer from souring.[1]Pasteurization aims to reduce the number of viable pathogens so they are unlikely to cause disease (assuming the pasteurized product is stored as indicated and consumed before its expiration date). Commercial-scale sterilization of food is not common because it adversely affects the taste and quality of the product. Certain food products, like dairy products, are superheated to ensure pathogenic microbes are destroyed. 2. Mention the type of microorganisms in milk. The types of micro organisms found in milk vary considerably, and are dependent upon the specific conditions associated with a batch of milk. Bacteria, yeasts, moulds, and bacteriophages are commonly encountered. Other viruses and Protozoa are seldom observed in milk products, except as occasional contaminants. 3. Mention the pathogenic bacteria present in milk. The pathogenic bacteria that are present in milk are Listeria Monocytogenes, Yersinia Enterocolitica, Campylobacter...

The framework allows for an understanding of the cross-sector economic influence of zoonoses using improved risk analysis and listing a range of analytical tools. The goal of the framework is to link the check outputs of animal and human disease transmission models, economic influence models and assessment of risk management options to gain improved understanding of factors affecting the acceptance of risk management plans so that investment planning includes the most promising interventions (or sets of interventions in an integrated fashion). A more complete understanding of the costs of the disease and the costs and benefits of control measures would promote broader application of the most efficient and effective control...

...Bad Bug Book Handbook of Foodborne Pathogenic Microorganisms and Natural Toxins Introduction Food safety is a complex issue that has an impact on all segments of society, from the general public to government, industry, and academia. The second edition of the Bad Bug Book, published by the Center for Food Safety and Applied Nutrition, of the Food and Drug Administration (FDA), U.S. Department of Health and Human Services, provides current information about the major known agents that cause foodborne illness. The information provided in this handbook is abbreviated and general in nature, and is intended for practical use. It is not intended to be a comprehensive scientific or clinical reference. Under the laws administered by FDA, a food is adulterated if it contains (1) a poisonous or otherwise harmful substance that is not an inherent natural constituent of the food itself, in an amount that poses a reasonable possibility of injury to health, or (2) a substance that is an inherent natural constituent of the food itself; is not the result of environmental, agricultural, industrial, or other contamination; and is present in an amount that ordinarily renders the food injurious to health. The first includes, for example, a toxin produced by a fungus that has contaminated a food, or a pathogenic bacterium or virus, if the amount present in the food may be injurious to health. An example of the second...

...BIOTERRORISM Name: 1. Introduction Historically, infectious disease outbreaks brought about by microbial species against human beings have caused far more mortality rates than war itself. Numerous cases of disease outbreaks in the past have been a major concern to health authorities, although such concerns have been partially addressed in the recent past. Examples of disease outbreaks in the past include: the infamous Bubonic Plague of the 14th century in Europe that led to the death of approximately a quarter of the continent’s population (approximately 25 million people); the influenza pandemic of 1918 to 1919 that led to the death of 21 million people; and the death of 95% of Pre-Columbian Native American people by measles, plague, small pox, influenza, and typhoid (Magner, 2009). Although there has been some response to such epidemics in the recent past, naturally occurring infections still remain the Achilles’ heel of today’s health systems. 2. Terrorism Versus Bioterrorism Despite the dark past in healthcare systems, current issues of the use of biological agents as means of mass destruction is alarming. Most of the countries across the globe are now faced with the daunting task of terrorism control, since this is one area where biological agents find a lot of use. According to Forst, terrorism may be defined as a “premeditated and unlawful use of violence [on] non-combatant populations having symbolic significance….” (Forst, 2009). Forst mentions that...

...Man versus Nature: Technology Versus Environment: Money Versus Wild Life Bristol Bay Although the fishing industry has long been associated with the contribution of marine pollution little work has been done on the effects on the industry itself of marine debris and other pollution. The fishing industry is responsible for discarded nets, hooks, fishing poles, and many times sunken boats, among other gear. In many circumstances this is not the intended plan when going fishing to catch their paychecks. In fact the fishing industry pays a high price for these losses from the time they have to replace their nets to the pulling of old nets and trash out of their new nets on a regular basis. When questioned about the effects of marine debris on their fishing activities, Shetland fishermen responded that 92% had recurring problems with accumulated debris in nets, 69% had had their catch contaminated by debris and 92% had snagged their nets on debris on the seabed. Many also experienced fouled propellers and blocked intake pipes. On average, 1-2 hours per week were spent clearing debris from nets. Debris could cause a restricted catch and many boats avoided particular fishing areas altogether due to the high concentrations of debris. It has gotten to the point for many fishers that they can no longer fish certain areas known to be well stocked with money fish due to the time consuming issues with trash and fishing debris in those specific waters due to left behind gear. Ultimately...

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...

...INTRODUCTION Infection remains the main cause of morbidity and mortality in man, particularly in developing areas where it is associated with poverty and overcrowding.In the developed world increasing prosperity, universal immunization and antibiotics have reduced the prevalence of infectious disease. However, antibiotic-resistant strains of microorganisms and diseases such as human immunodeficiency virus (HIV) infection, variant Creutzfeldt–Jakob disease ,avian influenza and severe acute respiratory syndrome(SARS) have emerged. In the developing world successes such as the eradication of smallpox have been balanced or outweighed by the new plagues. Infectious diseases cause nearly 25% of all human deaths. Two billion people one-third of the world’s population are infected with tuberculosis (TB),500 million people catch malaria every year, and 200 million are infected with schistosomiasis. 39.5 million people are living with HIV/AIDS, with 4.3 million new HIV infections in 2006 (65% in sub-Saharan Africa). The eight Millennium Development Goals (MDG) hope to be achieved by 2015. These are: eradicating extreme poverty and hunger, universal primary education, gender equality and empowerment of women, reduction in child mortality,improvement in maternal health, combating HIV/AIDS,malaria and other diseases, ensuring environment sustainability and developing global partnership for development.

...Section A: Basic Microbiology 1 SCOPE AND HISTORICAL DEVELOPMENTS IN MICROBIOLOGY “Science contributes to our culture in many ways, as a creative intellectual activity in its own right, as a light which has served to illuminate man’s place in the uni-verse, and as the source of understanding of man’s own nature” —John F. Kennedy (1917–63) The President of America The bacterium Escherichia coli INTRODUCTION AND SCOPE MICROBIOLOGY is a specialized area of biology (Gr. bios-life+ logos-to study) that concerns with the study of microbes ordinarily too small to be seen without magnification. Microorganisms are microscopic (Gr. mikros-small+ scopein-to see) and independently living cells that, like humans, live in communities. Microorganisms include a large and diverse group of microscopic organisms that exist as single cell or cell clusters (e.g., bacteria, archaea, fungi, algae, protozoa and helminths) and the viruses, which are microscopic but not cellular. While bacteria and archaea are classed as prokaryotes (Gr. pro-before+ karyon-nucleus) the fungi, algae, protozoa and helminths are eukaryotes (Gr. eu-true or good+ karyon-nucleus). Microorganisms are present everywhere on earth, which includes humans, animals, plants and other living creatures, soil,water and atmosphere. Microorganisms are relevant to all of our lives in a multitude of ways. Sometimes, the influence of microorganisms on human life is beneficial, whereas at other times, it is detrimental.

..."NATURAL PRESERVATIVES" Anthony C. Dweck Research Director, Peter Black Medicare Ltd., White Horse Business Park, Aintree Avenue, Trowbridge, Wiltshire, UK. BA14 0XB SUMMARY This paper looks at the theoretical development of a natural preservative system using the author's data base on medicinal plants as a source of references. The legal aspects of this concept are considered. The traditional methods of preservation, many taken from the food industry are summarised. The use of alcohol, glycerine, sugar, salt, dessication, anhydrous systems and temperature are amongst examples considered. The definitions of the many words used to describe the act of preservation are considered, and the confusion that results from the presence of the many synonyms is considered. e.g. antimicrobial, antibiotic, antiseptic, bactericidal, etc. Specific organisms are identified as being of particular interest, especially those standard organisms that form part of the B.P. challenge test. These include Candida albicans, Pseudomonas aeruginosa, Escherichia coli, Aspergillus niger and Staphylococcus aureus. A cross-section of plants mentioned in the literature as being specifically targeted at these organisms are considered. The paper concludes with Appendices of plant materials that have mention in the literature according to specific definitions, which may give researchers a potential introduction to future research.

...When it comes to understanding animals and the diseases they have, contract, and carry there is no limits. From dogs and cats to livestock and exotics it is necessary to learn and understand diseases from metabolic to degenerative or idiopathic, Neoplastic diseases and Toxic poisonings, Congenital and Genetic diseases to Immune related diseases, and Infectious and Contagious diseases to Parasitic Infections. There is a world that one can get lost in when it comes to learning about theses things. Some diseases have been around for years while others are still being studied with new ones occurring today in the modern world. Along with these diseases it is important to study and understand what causes them, what signs to look for, what species to look for them in, how to treat them, and how to prevent them from happening, IF you can even prevent them. Some diseases and conditions have vaccines to help with prevention and some do not, while some diseases are zoonotic meaning that they can be transmitted from animal to human. While there are hundreds upon hundreds of diseases to be looked at, the ten researched below are the ones once prevalent among the veterinary technicians job in the clinic; Hip Dysplasia and Ethylene Glycol poisoning in dogs, Hyperthyroidism and Rabies in cats, Strangles and Equine Recurrent Uveitits in Horses, Cryptosporidium and Fasciola Hepatica in Ruminants and Swine, Idiopathic Epilepsy in Aviaries, and Lymphoma in Ferrets.
