Background Research At some time in your life, you have probably heard the belief “a dog’s mouth is cleaner than a human’s mouth,” but have you ever wondered if it is really true? If you are a dog owner, you are probably on the receiving end of lots of slobbery kisses. Dogs are not afraid to eat away at bacteria-laden dead animals, a pile of feces or even household trash. Their behavior contributes to a mouth filled with a variety of different bacteria. Likewise, the human mouth is a complex system that humans rely on for a number of everyday functions from talking, to eating as well as kissing. Both the canine and human mouth is a perfect breeding ground for bacteria. How dirty is the mouth and which one has more bacteria: the human or canine mouth? …show more content…

They are the smallest and most abundant form of life on Earth. The word “bacteria” comes from the Latin word meaning small “staff.”They are so small that you need to use a microscope to see them. Bacteria are classified by their shape. The Bacillus Bacteria are shaped like rods or sticks. The Coccus Bacteria are shaped like spheres. The Spirillum Bacteria are shaped like spirals. Regardless of shape, all bacteria are one-celled organisms and reproduce by dividing in two. Many bacteria are vital to the survival of living things, while others cause disease. Some bacteria humans need in order to get nutrients into the body; these normally live in the intestine. Other bacteria reproduce inside the body and cause different infections - sore throats, ear infections, cavities, and pneumonia, to name a few. Other bacteria are used in labs to make things like medicine and vaccines. Is it amazing that some bacteria are vital to the survival of living things, while others cause

Alcaligenes Faecalis Experiment

636 Words | 3 Pages

According to the series of test that my group ran for our unknown specimen, we had a match with the bacteria known as Alcaligenes Faecalis. This bacterium belongs to one of the major group of gram-negative bacteria (Phylum Proteobacteria). Alcaligenes Faecalis (Genus, species) is a rod shaped (bacillus), 0.5-1.2 x 1.0-3.0 µm, round with scalloped margin (colony configuration growth), motile (with one to nine peritrichous flagella), gram-negative, non-fermentative bacteria, obligate aerobic, having oxygen as the principal terminal electron acceptor in the electron transport chain (ETC). We consider we have a match with the species Alcaligenes Faecalis because of the following reasons: Fermentation tests performed (Durham sugars) were negative, which indicate that our bacteria use a different metabolic means for growth (non-fermentative gram-negative bacteria).

Deadly Companions: How Microbes Shaped Our History By Dorothy Crawford

816 Words | 4 Pages

Readers not only learn why microbes emerge at these particular stages in human civilization and how they cause lethal infections, diseases, and pandemics, but also how microbes, with their dynamic interactions with humans, impact and shape human life. In addition, Crawford tracks human progress towards understanding the cause of communicable diseases and fighting against the disease-causing microbes with treatments and preventions, which includes antibiotics and vaccinations. In the final chapter of Deadly Companions, Crawford outlines our current situation with evolving pathogenic microbes despite the interference from modern advancement and knowledge. These killer microbes continue to exploit society; especially with poverty, travel, and drug behavior providing opportunities for our deadly companions to

Unknown Bacteria Number 5 Lab Report

1114 Words | 5 Pages

Being able to determining the identity of a bacterium is essential as treatments for different types of bacteria vary greatly. Without correct and timely identification of a bacterium, a patient’s condition is likely to worsen and the probability of death rises due to inaccurate treatment. The identification of bacteria is also crucial in the prevention of bacterial diseases. Identification of bacteria also aids the selection of antibiotics used against them. This assists in the reduction of the overuse and misuse of antibiotics which aids bacterial resistance to antibiotics.

Missing Microbes Summary

844 Words | 4 Pages

In the book Missing Microbes, the author, Dr. Martin J. Blaser discusses different types where the mysterious microbes are to be found. Dr. Martin also discusses his hypothesis in which talks about how over use of antibiotics has permanently changed the microbiome that humans live in, causing an increase in more modern diseases. The way Blaser lays the book is more like a journey; he traces his footsteps, and has the readers following the lead anxiously waiting on what he will inform them. There are a lot of doors in Science. Dr. Blaser chose to enter the door where facts and stories are to be learned everyday, in which there is no end, making that the beauty of science.

Of the Enterobacteriaceae family, there are genera that are in the normal human flora. Some species such as K. pneumoniae and E. coli are opportunistic pathogens which can capitalize on weakened host defenses and cause food poisoning (Baron, 1996). S. enterica secrete proteins that help aid in intracellular invasion and proliferation (Hensel, 2009). K. pneumoniae is a part of the normal human mouth, skin, and intestine flora, but can wreak havoc if inhaled (Ryan,
