Oftenly, both on and in man’s body, bacteria which have the ability to cause an infection are present. This ability of pathogenic bacteria to establish disease is reflected in possession of certain pathogenicity factors: toxins, surface structures and enzymes. These established complex relations’ income depends on host’s characteristics as well as on pathogen’s characteristics. ( Olgica Stefanović, Ivana Radojević, Sava Vasić
Many of which can cause infections and diseases that can irritate that can lead to death. The ways that they are hazardous are by damaging and breaking down the tissues of their host for food or by releasing toxins in the body, interfering with normal functions. Many can cause infections and diseases such as the Streptococcus pneumoniae, which causes pneumonia, an infection in the lungs and the Salmonella Typhi bacterium which causes typhoid fever. Some other diseases that are caused are tetanus, bubonic plague, syphilis, leprosy and many other deadly sicknesses. Another reason why bacteria are harmful is that they can be present in the food and water that we ingest, such as rotting our foods that we consume.
Introduction: Foodborne illnesses are any illness resulting from the food spoilage of contaminated food. Most foodborne disease caused by pathogenic bacteria, viruses, or parasites that contaminate the food. In addition to, other foodborne diseases it may happened due to poisonings caused by harmful toxins or chemicals that have contaminated food. Also, foodborne pathogens it can be acquired throughout contaminated water, from contact with animals or their environment, or through direct transmission person-to-person. In this article we will discuss about one of the most common foodborne pathogens it is campylobacter.
Types of Pneumonia 1) Bacterial Pneumonia Bacteria can affect anyone at any age. It can develop alone or after a severe cold or flu. The most common type of cause of bacterial pneumonia is Streptococcus pneumonia. It can be caused by bacteria Chlamydia pneumonia or nemophila bacteria. 2) Viral Pneumonia In many cases, pneumonia caused by the respiratory virus can cause particularly in young children and the elderly.
Yellow fever is an example of a communicable disease. Infectious disease is when bacteria, protozoans, fungi, or viruses enter the body, which will grow and produce more of their own kind. An example for an infectious disease would be like food poisoning or having upper respiratory tract infection. These terms are similar because both can harm the person that is sick. 2) What are the types of disease (by occurrence) There are many different types of diseases that can be either epidemic or pandemic.
These plates should be pre-weighted previously, pipette out 10 ml extract for each petri plate from the respective conical flask and dried till the solvent loss. 10 ml of extract solution contain = X gram
In this way they form a biofilm which is very resistible to antimicrobial agents such as detergents and medication. This is why bacteria are very likely to cause infectious diseases. 1.2.1. Steps of oral Biofilm formation Step 1: A thin layer of membrane called dental pellicle deposits on the teeth providing the appropriate surface for bacteria to attach. Step 2:
There are trillions of tiny bacteria all around us, many of which can cause infection. Antibiotics are medicines used to assist the body stop infections caused by bacteria. The term antibiotic means “against life” so technically any drug that kills
IDENTIFICATION OF UNKNOWN BACTERIA USING BIOCHEMICAL ANALYSIS Introduction: Bacteria play an important role in human life; they play a major part in decomposition of organic material, they are present in our digestive tract, some even fix atmospheric nitrogen for the plants. But at the same time there are many species of bacteria which can cause harm to living organisms. Identification of these bacteria plays a vital role in medicine and biological sciences. The identification can be done by two ways, either by performing biochemical tests or by sequencing the bacterial genome. For this experiment I conducted various biochemical tests to identify the given unknown bacteria.
Infection diseases happens when an unknown organism move into a person’s body and causes trauma such as bacteria, viruses, fungi and parasites. There are a lot of organisms in \human body which normally harmless and helpful, but some may cause disease if the condition were alter. These organism stay in human's’ body to help itself survive by reproduce and clonation. The infectious diseases can be easily passed from one to another. For instance, though the channel by bites from insects or animals.
