1: What are 3 factors that help microbes spread? (3 bonanza for microbes)

Response: The three factors or bonanzas, as the author describes that has been responsible for the increase in the spread of bacteria are: the rise of farming and cities as well as the development of world trade routes (Diamond 205).

Response: In the four stages of evolution between a specialized human disease from an animal precursor, the first are the diseases that we pick up from pets and domesticated animals but also those in the wild. Scratch-fever from cats, brucellosis from cattle and tularemia from rabbits are examples of the diseases we get in this stage (Diamond ...

DNA in Forensic Science

Forensic Science deals with investigations of suspects or criminals in crime scenes legally. In most cases, there are usually a lot of people involved in crime scenes. Some of them being innocent while some are the criminals. Also, there may be one criminal involved in an incidence. In Forensic Science, DNA is used to differentiate the individuals so that the criminal among them can be known. Additionally, DNA analysis is performed in the paternity testing. It enables the determination of a parent or parents of a child. DNA analysis is now being regarded as scientific evidence ("Application of forensic ...

Natural History of Tuberculosis

Zika virus was first isolated in the late 1940s from a sentinel rhesus monkey, Macaca mulatta, in Zika forest, Uganda. The name of the virus is thus associated with its first place of isolation. Later, the virus was recovered from mosquitos and humans in Uganda, Nigeria, the Central African Republic, Senegal, Malaysia, and Cote d’Ivoire. As the years progress, serological surveys continue to confirm the distribution of the virus infection in other countries such Tanzania, Mozambique, Ethiopia, Egypt, India, Thailand, Borneo, Democratic Republic of Congo, Cameroon, Liberia, Vietnam, and the United States. Today, Zika virus infection, at times ...

Bacteria refer to the regnum of prokaryotes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan). For the current moment, it accounts for more than ten thousand kinds of bacteria. The bacterium is recognized as one of the most ancient of living organisms, arising about 3.9 – 3.5 billion years ago. Bacteria have the substantial variation in the ways of metamorphic and energetic metabolism. Thus, autotrophs can synthesize all necessary organic molecules from non-organic compounds, whereas heterotrophs demand active organic compounds to transform them. The biggest degree of heterotrophs belongs to intracellular parasites. They are called saprophytes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan) and can ...

Identification of the Unknown Microorganisms

Unknown #1 Unknown #2 1. The identification of bacterial strains is a common practice in clinical and medical fields. The ubiquitously present microorganisms can be both, beneficial or harmful to the host they attack or inhabit. Since times, several biochemical characteristics have been identified for many bacteria that commonly are related to humans. These characteristics and morphology have been arranged in a systematic way to identify the targeted unknown microorganism along with ruling out the ones giving negative results for the characteristic tests. This way the search was narrowed down for each of the two unknown microorganisms. The Gram ...

Tuberculosis is a disease, which was known for mankind since ancient times. There are often suffering symptoms of tuberculosis in Egyptian mummies. Information about it is remained in the Indian Vedas, the ancient Babylonian clay tablets in the Greek manuscripts. Even Hippocrates knew how dangerous tuberculosis disease of the lungs is. In the eighteenth century every seventh inhabitant of Europe died because of tuberculosis. Infectiousness of tuberculosis has been already known for a long period of time. German scientist Robert Koch, bacteriologist was the first one 1882 to discover mycobacterium tuberculosis in 1882. This is the microbe that under ...

Immunizations in Children

According to World Health Organization (WHO), “Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine” (World Health Organization). This definition of WHO can be further elaborated by saying that the concept of immunization works by stimulation of the immune system. The immune system performs the function of protecting the body against disease causing agents. In its healthy condition, the body’s immune system has the ability to recognize any invading microbe. The leucocytes identify the microbes and produce antibodies against them. These antibodies are capable ...

Biotechnology has emerged as a major field few decades back but the art of science behind biotechnology primarily emerged with the discovery of natural process of fermentation by microorganisms. The microscopic world of microbes is diverse and huge as they are of multiple types classified into genus and species based on their morphological, biochemical and genetic abilities. They are helpful as well as harmful to the extremes for humans in many ways. Despite continuous efforts by biologists, their identity has been ambiguous and still a lot is waiting to be explored. Only 0.5% of the microbial world is known ...

Vaccinations have always helped every person who is vaccinated. Vaccinations have prevented numerous illness and disabilities since the time of their invention. Some diseases such as whooping cough, mumps, and measles still a pose huge threat though they can be prevented through vaccines. Many children in United States are suffering and being hospitalized, resulting in deaths every year due to this threat. I support vaccinations because they are safe, very effective, and any child who is vaccinated develops an immunity to fight illness faster than a child who is not vaccinated. Vaccines are thoroughly tested for safety and continuously ...

The field of microbiology was very limited until the discovery of the microscope, though it did exist in a very practical sense. Though scientists were ultimately wrong about what actually carried and transmitted the plague, for example, they were correct in hypothesizing that it came from an outside source. Between then and now, the microscope was developed, and has been improved upon more and more. Now we have a great classification scheme for prokaryotes (assuming bacteria). It follows the standard domain, kingdom, phylum, class, order, family, genus, and species. The standard for most eukaryotes is also the same for ...

Introduction

It is unknown how long Staphylococcus Aureus (S. Aureus or staph) has been on this planet. We have been too busy trying to conquer all of successful attempts that it has made to evade our weapons against to establish an intricate epidemiologic profile of it. We do know when it was discovered to be a harmful bacteria, though. One of the primary toxins of staph, PVL, was first discovered by an assistant in Belgium by the name of H. van de Velde in 1894. He was taking care of some rabbits in a laboratory and noticed a ...

It is a tiny single-celled body usually produced asexually at the tip of the hyphae by most non-flowering plants and fungi. They are functional for asexual reproduction by developing into the new individual without the formation of gametes. It is in Aspergillus spores.

Sporangiospores

The sporangiophores are the spores which are produced in the sporangia. Fungi produce them - mosses not included for generational propagation. Rhizopus uses it for spore formation.

Zygospore

In many fungi, the zygospore – a diploid reproductive stage in their life cycles is created by the nuclear fusion of haploid cells of the spores. The zygospores occur in ...
