Ear pain with several weeks of IV and oral antibiotics, usually fluoroquinolones. Acute otitis media is an infection of the middle ear. More than 80% of children experience at least one episode of otitis media by age 3 years. Acute otitis media is also most common in these first 3 years of life, though older children may also experience it. The most common causative bacteria are "Streptococcus pneumoniae", "Haemophilus influenzae", and "Moraxella catarrhalis". Otitis media often occurs with or following cold symptoms. The diagnosis is made by the combination of symptoms and examination of the tympanic membrane for redness, bulging, and/or a
Cell membrane the outer membrane is asymmetric because of proteins such as the aforementioned. Also, for the prokaryotic membranes, there are multiple things that can affect the fluidity. One of the major factors that can affect the fluidity is fatty acid composition. For example, when the bacteria "Staphylococcus aureus" was grown in 37C for 24h, the membrane exhibited a more fluid state instead of a gel-like state. This supports the concept that in higher temperatures, the membrane is more fluid than in colder temperatures. When the membrane is becoming more fluid and needs to become more stabilized, it will make longer fatty
