Otitis media (OM) is any inflammation of the middle ear and is very common in children. Acute otitis media is the rapid onset of OM with one of more of the following symptoms: otalgia, otorrhea, headache, fever, irritability, loss of appetite, vomiting, and diarrhea (Waseem, 2015). Otitis media with effusion normally occurs after an episode of acute otitis media. Patients may complain of hearing loss, tinnitus, vertigo, and otalgia. Chronic suppurative otitis media is a persistant infection…

The common symptoms of bacterial meningitis are fever, vomiting, severe and persistent headache, stiff and painful neck, confusion, unconsciousness, and seizures. One of apparent signs is that people who has infected are inability to lower their chin to chest due to stiffness in the neck. Symptoms can be varied depends on age as well. In infant or young children, they experience fever, cold, unusual cry, rapid breathing, or grunting, refusing food, and vomiting. In adults, besides those symptoms…

In the 1920s, A British researchers named Frederick Griffith studied bacterial pneumonia to find a vaccine for it. The specific bacteria was Streptococcus pneumoniae. Using streaking on a cultured Petri dish, the batterie was seperated into two strains, or colonies. The R-Strain was rough, and when injector into mice, it did not cause pneumonia, but the S-strain was smooth and slimy, and caused lethal pneumonia when injected. When the S-Strain was killed by heat, it did not cause sickness, but…

Summary: This is a 19yo male college student with a CC of acute onset of constant “gritty” or FB sensation to OU associated with 2/10 pain, erythema, lacrimation, and pruritus 2-3 days ago. There are no aggravating or relieving factors. Pt used OTC visible gtts with temporary relief to erythema only. Denies using any corrective glasses of contact lens. No crusting of lids or mucoid or purulent discharges. Reports occasional rhinorrhea with intermittent nasal congestion without sneezing. Denies…

between the lungs and inner surface of the chest wall. Pyothorax (J86.0, J86.1), usually develops after pneumonia. The pus can not be coughed out but drained out by a needle or even surgery. The most common bacteria that causes Pyothorax is Streptococcus Pneumoniae, and Staphylococcus aureus. An acute condition is where the symptoms usually materialize out of no where and get worse very quickly. An acute pain is the response to tell you and your body that you have been hurt. Some examples are…

Normal flora is the colonisation of human tissues by a diverse mixture of microorganisms. This colonisation begins at birth with pioneer species, depending on physiochemical factors. The normal flora inhibits the skin, oral cavity, upper respiratory tract, gastrointestinal tract, urogenital and conjunctival membranes. They are commensal bacteria; getting shelter and nourishment from the host without causing harm (Gould, 2012). To a healthy individual, most normal flora is harmless, however some…

uncommon. Meanwhile, neomycin acts on both gram-positive and gram-negative pathogens including staphylococci, Proteus, Enterobacter aerogenes, Klebsiella pneumoniae, Salmonellae, shigallae, Haemophilus influenza, Pasteuerella, Neisseria meningitides, Vibro cholera, Bordetella pertussis, Bacillus anthracis, Corynebacterium diptheriae, Streptococcus faecalis, Listeria monocytogenes, Escherichia coli Mycobacterium tuberculosis, Borrelia and Leptospira interrogans (L. icterohemorrhagicae). Despite…

2. Describe the pathophysiology of COPD Patients with COPD are always associated with smoking. This diease is develops from prolonged exposure through inhalation of harmful or poisonous particles such as nicotines from smoking, dust, fumes and air pollutions. These irritants can stimulate the inflammation of airways and irritates the lungs. (Lewis et al., 2014 p732). When this irritants is being inhaled, the cilia in the lungs are damaged that causes persistent cough and increase mucus…

Fredrick Griffith’s 1928 experiments with Streptococcus pneumoniae demonstrated that an unknown component, later found to be DNA, existed inside every living thing and had the power to pass on its genetic material to other organisms (B). In his experiments, Griffith injected groups of mice with different…

Acute bronchitis is the sudden development of inflammation of the trachea and major bronchi. It is caused by mainly by viral and sometimes bacterial infection. However, inhaling substances that irritate the lungs, such as tobacco smoke, and dust can cause it. The main symptoms for a 55-year old include a hacking cough that last for up to three weeks with or without phlegm, and sometimes dyspnea and wheezing. The typical community acquired pathogens (CAP) involved with acute bronchitis are…
