Introduction

The Zika virus causes an illness known as Zika virus disease (Zika). The transmission of Zika virus occurs via the bite of an Aedes mosquito that is infected (CDC, 2016). Zika belongs to the genre Flavivirus and the WHO (2015) has identified it as “an emerging mosquito-borne virus.” The virus causes a mild illness that lasts a few days to a week (CDC, 2016; WHO, 2016). Thus, many people with the disease do not seek medical help. However, the greatest concern associated with Zika is microcephaly. This birth defect results from a Zika infection during pregnancy. This defect is ...

The advances in biotechnological field have made it possible to understand the genetic role behind molecular mechanisms to large extents. This in depth understanding of biological processes has paved ways to treat the untreatable aiding the human existence in multitudes of aspects like food, health, bioremediation, mining, biopharmaceutical production and much more. This microbial world is vast and has been a platform for human beings to explore their biological systems as they are simpler cells and can be manipulated with much ease than complex systems. The DNA harnessed within the cells are the molecular entities that have been targeted ...

Introducing the Microorganism

Candida albicans is a human microbiome member. It is opportunistic in nature and exists as a non- harmful resident of the genitourinary tract in 70% and of oral cavity in 75% of humans. It has shown opportunistic behaviour leading to infections in case of individuals whose immune system is compromised (immunocompromised). C. albicans is mainly responsible for 2 types of infection: superficial candidiasis like vulvovaginal or oral infections and systemic life-threatening infections. C. albicans has been observed to cause vulvovaginal candidiasis in approximately 75% of women. C. albicans is an obligate and diploid organism possessing 8 pairs of chromosomes, ...

Abstract

Handwashing is an important process in controlling microorganism transmission and infectious diseases. The purpose of this experiment was to determine the effectiveness of different antibacterial hand cleaners (soap, alcohol hand sanitizer and ethanol soaked wipes) on killing bacteria. Hands were sampled without cleaning with antibacterial hand cleaner (control), and after cleaning with antibacterial soap, alcohol sanitizer, and ethanol soaked wipes. Samples were taken with a sterile cotton swab and inoculated on agar plates. Each experiment was done three times. Colonies were counted, mean values and standard deviation were calculated, and data was reported. Alcohol and sanitizer and ethanol soaked ...

QUESTIONS ON BIOCHEMISTRY

Questions on Biochemistry Describe the difference between an obligate and a facultative aerobe. Obligate and facultative aerobes are the same in terms of their ability to use oxygen in their respiration process. However, obligate aerobes requires oxygen to oxidize substrates such as sugar and fat to produce ATP (energy). Obligate aerobes are more efficient in converting substrates to ATP. The key process in aerobic respiration is the conversion of sugar to ATP shown in reaction 1 below:

In the reaction 36 molecules of ATP is produced per molecule of glucose. It is actually a slow process which comprises 3 ...

Vaccination for children

It is better to prevent it than to cure it. That is the advocacy of all the health organizations throughout the world. Vaccines are a type of weapon that can be used in order to shield oneself from the known diseases, and sometimes, with diseases that have yet to find remedy to them. A vaccine is a biological agent that is injected to our bodies in order to provide immunity to their corresponding ailment (WHO, n.d.). Nowadays, more and more diseases are discovered with the advancement of technology. However, not all are able to find the cure for all ...

Discovery of ultraviolet light

Ultraviolet radiation is very significant in the tanning individual who are interested in making their skin look like leather as well as for vampires killing, yet it cannot be seen or else felt. The question is then, how did people discover existence the existence of ultraviolet light? Although light is comprehensively abundant when it comes from its primary source the sun, and it is tough to get hold of it because it travels at very high speed than anything else globally. Since light is subsequently insubstantial, for many years, individuals managed only to collect a few frequencies without knowing ...
