Streptococcus

Mary Farmer has Gram-positive cocci, Streptococcus aureus, and Brian Evans has Gram-negative bacilli, Escherichia coli. From this, we know that Culture A’s bacteria has a thick cell wall with no outer membrane and Culture B has a thin cell wall with an outer membrane. From the results of the Gram’s…

Pneumonia is viral, bacterial, and fungal. According to World Health Organization, pneumonia comes in the different forms such as Streptococcus pneumonia, which is a type of bacteria. Another cause of bacterial pneumonia is the Haemophilus an influenza type b (Hib). We have the respiratory syncytial virus type which is the most common viral cause of pneumonia. Then we have pneumonia in infants infected with HIV called Pneumocystis Jiro ve ci. There is various way pneumonia can be spread. It can…

splenectomy. Asplenic patients are at high risk for infection by encapsulated organisms due to a decreased ability to clear them. This increased risk is due to a decrease in IgM, opsonins, and splenic tuftsin. The most common encapsulated organisms are Streptococcus pneumoniae, Haemophilus influenzae type B (Hib), and Neisseria meningitidis.Vaccination against these organisms is imperative in order to prevent infections and overwhelming post-splenectomy sepsis (OPSS), a serious condition where…

acids/neuraminic acid or from non-sugar subunits such as pyruvyl, acetyl and formyl group.Capsules are either synthesized at the level of cell membrane or extracellularly as done by Streptococcus mutans using extracellular enzyme glucosyltransferase in the oral cavity. Individuals infected with capsulated bacteria like Streptococcus pneumonia, Klebsiella pneumonia, Neisseria meningitides, Haemophilus influenza, Bacillus anthracis, Yersinia pestis and others show anti-capsular antibodies in their…

Dental Caries: The big culprit Dental caries is a dental terminology which can be otherwise called tooth decay. The tooth is the hardest structure is our human body and is made up of organic and inorganic contents It is approximately 45% inorganic material (mainly hydroxyapatite), 33% organic material (mainly collagen) and 22% water. Dental caries is a complex procedure that involves the combined action of bacterial toxins in an acidic environment that causes loss from the tooth structure. The…

Biological functions: The main biological functions for CRP to determine via its ability to identify pathogens and injured cells of the host and mediate their elimination via activating the complement system and phagocytic cells (Brundish and Baddiley,1968 ; Weiser et al., 1997). CRP binds to microorganisms and mediates their killing to more recent observations of protection against bacterial pathogens in CRP transgenic mice. The most significant evidence has supported the notion that CRP plays…

Biofilm, like Streptococcus pneumoniae and Streptococcus pyogenes, both deadly disease causing pathogens, were found on toys, books, cribs, and hands. Four out five stuffed toys and cribs contained one or both of the biofilm pathogens. Within the daycare they found bacteria that had been…

Cellulites could be defined as an infection of the skin and tissues beneath the skin. I t affects the deeper and outer layer of the skin. The causative organisms could be staphylococcus and streptococcus or methicillin –resistant staphylococcus area (MRSA) or could be as a result of other types of bacteria like pneumococcus or clostridium.(Medicinenet.com). Based on the given objective and subjective data, Ms. G. has a non-purulent cellulitis with the following cardinal signs and symptoms; pain,…

Pneumonia is caused by an inflammatory response to an organism such as streptococcus pneumoniae or escherichia coli. This inflammation occurs in the alveolar sacs and the alveoli are filled with fluid, neutrophils, and there is also an increase in mucus production.The inflammation of the alveolar sacs leads to a decrease in gas exchange which leads to hypoxia (Lewis, 2014). There are several types of pneumonia and they include: community-acquired, medical care-associated, aspiration, and…

nevertheless they also appeared as single cells and short chains of few cells (four cells chain is visible at the Gram film). Morphological appearance of bacteria, Gram stain and presence of the organisms in the sputum suggest that it may be Streptococcus pneumoniae (Allegrucci and Sauer, 2006; Hoskins et al., 2001). To confirm identification of organism, future microbiological testing is required. Although bacteria present on the Gram film appears…
