The Relationship between Ketosis and Infectious Diseases
Ketosis is a metabolic disease that occurs when cows are in negative energy balance due to a decrease in DMI prior to parturition that does not increase at the same rate as energy requirements for lactation. This metabolic stress results in altered nutrient metabolism and immune system dysfunction. This processing of metabolic energy resources causes ketone bodies to accumulate in bodily fluids such as milk, blood and urine . While clinical cases of ketosis are generally less that 5%, some studies estimate the incidence of subclinical ketosis at up to 40% . The disease is more common in regions managed for intensive production . As a metabolic disease ketosis is linked to infectious diseases such as mastitis by causing immune system depression, this means that ketosis has the potential in incur huge costs and other health problems on your dairy operation.
Periparturient Disorders

This decrease in DMI causes a shortage of metabolic glucose precursors needed for milk synthesis, resulting in a negative energy balance. Periparturient disorders that can be responsible for ketosis include calving difficulty, retained placenta, endometritis and milk fever . Since ketosis depresses the immune system, cows are more susceptible to infectious diseases such as mastitis, metritis and endometritis, forming a risk cycle that will continue unless appropriate steps are taken to break the
We actually saw this change occur by watching the RER values increase. At the 2:30 mark Kerbi was using 100% fats as her fuel source with an RER of .75. One minute later, at an RER of .80 she was using 50% fat and 50% carbohydrates. In between minutes 6:30 with and RER of .99 and less than the 7:00 mark with an RER of 1.04 she was using primarily 100% carbohydrates as her fuel source. Lactate began accumulating in Kerbi’s blood at the 7:00 mark with an RER of 1.04, a speed of 3.4 and a grade of 14. I know this because her RER was above the 100% carbohydrate level of 1.00, and this is also the time at which she felt uncomfortable to the point that the test
Lactose intolerance (LI) is the inability of some humans to digest the lactose sugar contained in most dairy products and foods made with dairy products. LI has numerous readily apparent physical symptoms such as gas, cramps and diarrhea (Houts 110). More importantly, LI may lead to malnutrition in those people affected because of the loss of milk's important nutrients. Not everyone is affected by LI. In fact, genetic background rather than any other health or cultural factor seems to best predict LI. The inability of humans to digest lactose has enormous health consequences, particularly among the poor populations of the U.S. and the developing third-world countries.
Mad cow disease is caused by prions, "weird mutant proteins that are found in brain and spinal tissue"1. Another name for mad cow disease is called bovine spongiform encephalopathy (BSE) and the definition is "a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion"2. It started from what is called a prion protein then it turned into a pathogenic, and then it starts to damaged the brain of a cattle. There's another name for this disease and it's called Creutzfeldt-Jakob Disease "a form of progressive dementia characterized by loss of nerve cells and degeneration of nerve cell membranes leading to the production of small holes in the brain. It is rare, degenerative, and invariably fatal"3. This disease happen in human causing lapses in the memory, mood swings similar to depression, lack of interest and social withdrawal3. It is said that this disease has no tr...
Bloodborne Pathogens are pathogenic microorganisms that can eventually cause disease. They are found in human blood and other bodily fluids such as synovial fluid, semen, vaginal secretions, cerebrospinal fluid and any other fluid that mixes or has contact with blood. The bloodborne pathogens are pathogenic, which means they are disease causing, and they are also microorganisms, which means that they are very small so the human eye cannot see them.
E. Coli is a bacteria that is inside your intestines that helps you break down food. When cows are fed corn, it also decreases the healthy acids such as Omega-3 and increases Omega-6 which is unhealthy. We should also care about their living conditions because a cow is in one area for most of the day just eating corn and when cows eat corn they tend to poop a lot. It is crowded in the eating area for cows so when they poop it falls on the ground and they eat so much corn that they just keep pooping so eventually they start stepping in it and this would cause them to get diseases. Some farmers when they slaughter them do check for diseases but some don’t, so the diseases travel with the cow and onto your dinner plate which means that you could be eating an infected cow without knowing it.
The majority of clinical cases of laminitis occur in pastures where there is an accumulation of rapidly fermentable non-structural carbohydrates (NSC) such as fructans, simple sugars or starches (Geor, 2010). Pasture-associated laminitis has major economic and welfare implications in the equine sector. Increased risk factors include insulin resistance, increased insulin secretory response, hypertriglyceridaemia and obesity (Asplin, et al., 2007; Carter, et al., 2009 and de Laat, et al., 2010). Insulin resistance has been associated with a number of problems in the horse, most notably laminitis.
Pathogens are a type of microorganism that spreads viral and bacterial diseases. These diseases when present in human blood and body fluids are known as blood borne pathogens, and can spread from one person to another. (Worcester polytechnic institute) The most serious types of blood borne diseases are the hepatitis B virus (HBV) and hepatitis C virus (HCV), which can cause liver damage; and HIV (human immunodeficiency virus), which is responsible for causing AIDS (acquired immune deficiency syndrome). The blood borne pathogens can be spread when the blood or body fluids (semen, vaginal fluid, breast milk, and amniotic fluid) of an infected individual comes into contact with mucous membranes or an open sore or cut on the skin of another person. Mucus membranes are located in the eyes, nose, mouth, and other areas as well. ("Bloodborne pathogens: MedlinePlus Medical Encyclopedia") Two of the most common ways that pathogens are transmitted is through the exchange of fluids during sexual intercourse or by sharing infected IV needles.

Infectious diseases are the disorders caused by organisms such as bacteria, viruses, fungi or parasite who live both inside and outside our bodies and are normally helpful but can cause infectious diseases to the human (body) system under certain conditions. And for a disease to be infectious, there is what is called ‘’chain of infection’’ that takes place before. And this can be seen in the below diagram:
Patients seek health care services to get relieve or complete resolution of their health problems. Unfortunately, some end up with hospital acquired infection (HAI). HAI have a negative effect on the patient, the payer and the institution. This paper discuss the author’s interview with a health care provider on challenges encountered in addressing infection prevention, risk management strategies used in the organization’s infection control program , risk monitoring and maintenance and his view on infection prevention. HAI are preventable and individual health care provider, their institution, the patient and any other player involved must perform their role in infection control to reverse the current trend.
‘Ketoacidosis’ is a common complication, especially of Type 1 Diabetes. It is the accumulation of ketones and acids in the blood. When the cells cannot utilize glucose as a source of fuel, they breakdown the fats and lead to development of ketoacidosis.
Diabetic Ketoacidosis (DKA) is a serious disease with complications that may have fatal results in some cases. DKA is defined as an insulin deficiency that occurs when glucose fails to enter insulin into muscles such as: liver and adipose tissue. When there is an accumulation of ketones, it leads to metabolic acidosis which causes nausea and vomiting, as a result fluid and electrolytes are lost (Gibbs). There are many complications of diabetic ketoacidosis, some of the most prevalent are: Cerebral Edema, Hypoglycemia, and Acute Pancreatitis.
What is Foodborne Illness? According to a medical dictionary, foodborne illness is an acute gastrointestinal infection caused by consuming food contaminated with pathogenic, bacteria, toxins, viruses, prions or parasites. Such contamination was caused by improper food handling, preparation or storage of food. Contacts between food and pests, especially flies, cockroaches and rodents are a further cause of contamination of food. Foodborne illness can also be caused by adding pesticides or medicine to food or consuming or by accidentally consuming naturally poisonous substances. That is why foodborne illness can also be called food poisoning.
Even though there are numerous families that struggle to put food on the table, protein deficiency is rare in the United States, but can be seen in third world countries like Africa. However, protein deficiency disorders can occur even in the United States with people suffering from “alcoholism, anorexia nervosa, or certain intestinal tract disorders, [as well as] those who are elderly, have limited incomes, and are chronically ill”(Schiff 2013). Under nutrition of any kind is due to a lack of food in some fashion whether from crop failures, political unrest, or civil wars, but the etiology of Kwashiorkor and other protein deficiencies is often more complicated. Protein energy malnutrition (also known as PEM) affects people who do not consume sufficient amounts of protein. According to the World Health Organization (WHO), more than 18% of children are underweight due to malnutrition of some kind, including protein-energy malnutrition. There are in fact two types of PEM, kwashiorkor and marasmus. Kwashiorkor is the most common and widespread nutritional disorder in developing countries, primarily occurring where mothers breastfeed their infants until they give birth to another child. The older
In the 1960s, doctors in the United States predicted that infectious diseases were in decline. US surgeon Dr. William H. Stewart told the nation that it had already seen most of the frontiers in the field of contagious disease. Epidemiology seemed destined to become a scientific backwater (Karlen 1995, 3). Although people thought that this particular field was gradually dying, it wasn’t. A lot more of it was destined to come. By the late 1980s, it became clear that people’s initial belief of infectious diseases declining needed to be qualified, as a host of new diseases emerged to infect human beings (Smallman & Brown, 2011).With the current trends, the epidemics and pandemics we have faced have created a very chaotic and unreliable future for mankind. As of today, it has really been difficult to prevent global epidemics and pandemics. Although the cases may be different from one state to another, the challenges we all face are all interconnected in this globalized world.
Food borne illnesses are caused by consuming contaminated foods or beverages. There are many different disease-causing microbes, or pathogens. In addition, poisonous chemicals, or other harmful substances can cause food borne illnesses if they are present in food. More than two hundred and fifty different food borne illnesses have been described; almost all of these illnesses are infections. They are caused by a variety of bacteria, viruses, and parasites that can be food borne. (Center 1)
