(Table 1) Table 1: Individual results of Brassica mean root growth (mm). These were treated with Bacillus pumilus and Variovorax paradoxus under water and salt water (100mM‚ NaCl) conditions. 14 seeds were treated for each sample data set‚ but not all germinated. The sections where no results are shown‚ was due to dehydration of the petri dishes. Standard

Leprosy Mike Wallis Leprosy or Hansen’s disease‚ is a chronic‚ infectious disease that mainly affects the skin‚ mucous membranes‚ and nerves. A rod shaped bacillus named Mycobacterium leprea‚ causes the virus. Mycobacterium leprea is very similar to the bacillus that causes tuberculosis. The reason Leprosy is also known as Hansen’s disease‚ is because it was first identified in 1874 by a Norwegian physician named Gerhard Henrik Armeur Hansen. Leprosy appears in both the Old and New Testaments

Check smear and yeast smear contain cocci with direct staining. At direct staining plaque smear contain cocci and bacillus. Yeast with indirect staining contains cocci as well. On same picture bacteria are singled while on some pictures bacteria are in group and uneven clusters. Different type of stain plays role to differentiate the shape of bacteria. C: When we are

How do people "catch pneumonia"? Some cases of pneumonia are contracted by breathing in small droplets that contain the organisms that can cause pneumonia. These droplets get into the air when a person infected with these germs coughs or sneezes. In other cases‚ pneumonia is caused when bacteria or viruses that are normally present in the mouth‚ throat‚ or nose inadvertently enter the lung. During sleep‚ it is quite common for people to aspirate secretions from the mouth‚ throat‚ or nose. Normally

With this information and the results of the lab tests‚ it is apparent that enzyme A is Aspergillus oryzae (fungus)‚ enzyme B is Bacillus licheniformis (bacteria)‚ and enzyme C is porcine (pig). This experiment shows how enzyme function can be affected by concentration‚ temperature‚ and pH. The function of this particular enzyme is to breakdown starch and produce maltose. Each

Guillain-Barre’ Syndrome (GBS) is a common cause of acute onset weakness. It is an immune-mediated disease that is usually preceded by gastrointestinal or respiratory tract infection in most of the cases. Various pathogens like Mycoplasma pneumonia‚ Campylobacter jejuni‚ Epstein Bar virus and Cytomegalovirus are involved in its pathogenesis and immune response directed against these organisms may cross react with myelin sheath and other neural tissues causing weakness.1 it occurs in whole world with

0314 Biofilms in Chronic Wounds: Current Research and Future Direction ABSTRACT Chronic wounds continue to be a significant healthcare problem. Although myriad factors have been implicated in impaired wound healing‚ recent research has focused on the role of matrix-based bacterial communities called biofilms that are often associated with chronic wounds. Various in vitro and in vivo models have been developed to study the role of biofilms in non-healing wounds. Basic science and clinical
