Vibrio cholerae

showed that Zn-sulfate at concentrations between 1.2 and 1.8 mg/ml inhibited the growth in enteric pathogens commonly associated with diarrheal disease (Salmonella typhi, Salmonella groups A, B, C, D and E, Escherichia coli, Enterobacter, Shigella and Vibrio cholera). Our results seem to indicate that Giardia is more sensitive to Zn than these enteric…

INTRODUCTION This paper looks at the difference between gram negative and gram positive bacterium. This is important when doing gram staining experiments. It also looks at the importance of microbiology. DIFFERENCES OF GRAM NEGATIVE AND GRAM POSITIVE BACTERIUM There are notable differences between the gram negative and gram positive bacterium. Gram negative bacterium is surrounded by a thin peptidoglycan cell wall while Gram positive has a thick layer of peptidoglycan. The peptidoglycan around…

What is monsoon season? This monsoon word come from Arabic word which is wind patterns due to replacement of weather patterns. Monsoon typical definition is a season of wind reversing followed by corresponding changes in atmospheric calculation and precipitation . It is related with the asymmetric heating of sea and land. On the other word, monsoon also means rainy phase of pattern that are changing seasonally even though there is dry phase. The annual average of rainfall is 2420 mm for…

compromise shrimp health leading to ion regulation stress (Lemaire et al., 2002; ABCC, 2005). Tendencia et al. (2010) have noted the combined role of water temperature, salinity and Vibrio count in the risk of WSSV infections in P. monodon in the Philippines. Salinity is an important factor which determines the survival of V. cholerae (Thomas et al., 2006), the newly emerging pathogen of P. monodon along the Cochin backwaters (Joseph et al.,, 2015a). Acute low salinity stress was found to affect…

Bacteria Basics The Cambridge Online Dictionary characterizes bacteria as “very small organisms that are found everywhere and are the cause of many diseases” (Cambridge University). Bacteria is all around no matter where someone were to go. Bacteria can be very dangerous. People are exposed to bacteria from the time they are born to the day they die. Much of society think of public restrooms as bacterial feeding grounds, but what about high schools? Do high schools have dangerous sorts of…

The Ghost Map by Steven Johnson is a true story of a terrifying outbreak of cholera and how Dr. John Snow and reverend Henry Whitehead used their knowledge of the disease to find out how prevalent it was over the whole city of London. The disease may have been unfamiliar to them, but common to the millions of people around the country, whose living conditions and sanitation processes were not as good or advanced as theirs. The story reflects the world through the wide varieties of disciplines,…

The American Industrial Revolution was a change in human life conditions that took place in the late eighteenth and early nineteenth centuries. There was change in technology, society, education, economy, culture, and medicine. Each were very essential in the growth of the economy. Public Health was something that had to be focused on during the Industrial Revolution. Without public health, how would people survive? Doctors needed technology for resources, education to be well-educated and…

How John Snow’s Skepticism and Open-mindedness Influenced His Method of Conducting Research At the beginning of the 18th century little was known about cholera transmission or disease communication in general. The miasma theory was in full force. Most of the science world accepted the miasma theory and completely rejected any other theory for disease transmittance. This greatly hindered advancements in research of communicable diseases because miasmas were understood as a fact and no…

Health can be defined from different perspectives, thus leading to wide and varied meanings of health, biomedical and social models are used to elucidate the views of ill-health. This paper will firstly compare and contrast between biomedical and social models. Secondly, it will discuss how and why the social model has become more applicable over the last fifteen decades. Consequently, its effectiveness in expounding high incidences of acute rheumatic fever (ARF) and rheumatic heart disease…

Everybody loves the big city of Chicago, and knows that our drinking water comes from Lake Michigan. Well, imagine that water being filled with sewage and chemicals. That's the way that Lake Michigan used to be, and thanks to reversing the river, we will never have that problem again. A closer study of this historical event will illustrate how the workers completed this impossible sounding task, what impact this had on the Chicago people, and how reversing the river may have created more…
