There are three types of pathogens that cause meningitis. The first type of pathogen is Haemophilus influenzae type b. It is an aerobic gram-negative bacteria, meaning they have relatively thin cell walls and can be resistant to antibiotic treatment. In 95% of invasive diseases are caused by type b. Before the introduction of a vaccine, it was the leading cause of bacterial meningitis most common in infants. The organism colonizes in the nasopharynx (the upper part of the throat behind the nose) and can sometimes invade the bloodstream and cause infection at a distant site.
Neisseria meningitides is a bacteria that causes meningoccal disease. It is aerobic, Gram-negative bacteria that causes serious, sometimes fatal, infection

An MRI indicated inflammation of sulci, a groove in the brain, vascular congestion and cortical edema or fluid on the brain. A spinal tap was obtained from the patient and because of possible pneumococcal meningitis, an intravenous therapy with a combination of a steroid and antibiotics. Streptococcus suis was identified and the patient was asked about any recent contact with swine. For several weeks, he had been slaughtering, by hand, several non- commercially raised pigs for a luau. And although he did not recall any mucosal exposure to the pig blood or secretions, there is no known route for infection to humans. He did not wear any type of protective gear, i.e., gloves, apron or facemask. His exposure to pigs blood, skin and organs was extensive. During the slaughter process, his hands sustained multiple cuts. It is possible that the bacteria entered through those cuts as no other church members who participated in the preparation became ill. Treatment of ceftrixone and a 4-day course of dexmathasone was prescribed and his headache improved. He was discharged after 6 days and given a 2- week course of IV ceftrixone. After 1 day of discharge, he was affected again by headaches accompanied by a mild hearing loss. After a repeat spinal tap was administered, it was concluded that the headache was a result of residual meningeal/cerebral edema (swelling) that resolved
Bacterial meningitis is the swelling of the meninges. In the back of the brain, there are three protective membranes called the meninges (Mandal). During bacterial meningitis, bacteria invade the brain. This causes the immune system to enter and try to stop the disease (Mandal). In doing so, the meninges swell to stop the spread the virus, but this unfortunately causes damage to the brain and spinal area (Mandal). A person would get bacterial meningitis if their body was invaded by some of the germs that can cause it.
The patient was seen on June 1, 2015 secondary to vertigo. These symptoms did resolve completely.
Streptococcus Pyogenes is a very diverse bacteria with effects ranging from nothing or a mild sore throat, to flesh eating disease, causing death in 40-60% of patients. The major and most common illnesses associated with this bacteria
Meningitis occurs when bacteria or viruses invade the bloodstream and infect the meninges. The bacteria or viruses multiply rapidly and cause the meninges to inflame and swell. The brain is subjected to an increase in pressure that can cause symptoms such as a headache and a stiff neck.
Group B Streptococcus agalactiae is an important Gram-positive bacterial pathogen that cause a wide variety of clinical infections, ranging from septicemia to meningitis. The reported lethality of severe S. agalactiae infections is ranging from 4 to 6% in the United States. Of note, it has been suggested that the incidence of neonatal disease is considerably greater than reported, because the requirement for positive cultures from blood or cerebrospinal fluid may underestimates the true burden of disease. Therefore, in this review I focused on virulence factors of S. agalactiae in order to elucidate aspects of the infection.
N. meningitidis is an obligate aerobe, which means oxygen is essential to its survival and growth (Acharya, 2013). Neisseria meningitidis utilizes oxygen through aerobic respiration in order to create ATP (Acharya, 2013) In addition, N.meningitidis also converts nitrate into nitrous oxide through denitrification ( Rouphael & Stephens,2015)
Also, contraction is very possible through the skin via abrasions both small and large. This type of infection would be contracted from exposure to other people harboring the bacteria, bacteria in the air, or bacteria on the injured person. Being infected this way can rarely result in necrotizing fasciitis. It is also very possible, albeit very rare, that Streptococcus pyogenes can be transmitted through food, most notably milk and its products. This form of infection is usually caused by improper or lack of pasteurization of the milk. The bacteria that are responsible hardly ever come from an outside source, and are usually present within the cow when infected milk is produced. However, these two other methods of transmission are far less likely than the usual human-to-human respiratory infections. (6,2,1)
Herpes encephalitis is an infection of the cerebrum by herpes simplex virus 1. This can cause hemorrhagic necrosis of the temporal lobes leading to RBCs in the CSF, along with seizures and psychiatric symptoms. A CT scan of the head will reveal the temporal lobe abnormalities. With viral infections, lumbar puncture will reveal a slightly elevated opening pressure (above 180-mmH2O), around 100–1,000 lymphocytes, normal CSF glucose, and increased proteins. In this case, empiric therapy should be started before CT due to the poor prognosis of the disease and permanent neurological damage that may rapidly develop. Its incidence has a bimodal distribution, peaking in childhood and middle-aged adults (as seen in this case). The involvement of the temporal lobes is thought to be due to the virus having access to this area via the branches of the olfactory
The inner part of the nose and the back of the throat of a group member were swabbed in this experiment, in order to see if the bacteria Neisseria or Streptococcus were present in these locations. The features that make it easy to identify these two types of bacteria are that an oxidase test can be done for the Neisseria bacteria and using a blood agar to identify beta hemolytic species of the Streptococcus. Using the agar plates, the colonies were put through a few tests to see if the bacteria grown was the wanted pathogens or not. A prediction that Staphylococcus aureus would not be found in the nose of the group member, because many people do not possess this certain bacteria as a part of their normal microbiota, and that it would be expected to find the bacteria Neisseria and Streptococcus in throat. The throat is exposed to two places of entry, the nose and the mouth. These two openings allow for more bacteria to enter.
In the case of bacterial meningitis no one casual organism causes all of the cases, but rather
Meningitis can be destructive without proper understanding of what it is caused by. There are three types of meningitis- bacterial, fungal, and viral. Contrasting factors tend to arise during a comparison of them. One of the most notable areas that viral, fungal and bacterial meningitis differ in are their treatment ability. However, they have the same general affects on the human body. In any case, there are tests that doctors can utilize in order to discover if the meningitis is bacterial, fungal, or viral.
Meningococcal disease is a large concern in the medical field because it is unbiased towards the patients it infects. There has been limited success in trying to eliminate this disease. Antibiotics play a role in helping to treat patients with bacterial meningitis, and steroids have been tested to help reduce risk factors. Prevention has also become a key issue because meningitis can only be spread through direct contact with infected body fluid. The best prevention is to maintain clean hygiene. Vaccines are another way of preventing disease. However, there are multiple serogroups of meningitis that makes creating a universal vaccine extremely difficult. So far, there have only been two
Meningitis is an inflammation of the meninges, membranes that surround the brain. This can extend as far as infecting the cerebral spinal fluid on top of causing the tissue to swell. Meningitis comes in two major forms; bacterially and virally. However, having bacterial meningitis is much more severe than viral meningitis. There is a lot more danger in having a bacterial infection within the brain than a viral infection within the brain. What makes bacterial meningitis so lethal is that “even when the disease is diagnosed early and adequate treatment is started, 5% to 10% of patients die, typically within 24 to 48 hours after the onset of symptoms. Left untreated, up to 50% of cases may die, (6) or there
Meningitis is the inflammation of brain and spinal cord membranes and is caused by either a viral infection or bacterial infection. Bacterial meningitis is a dangerous disease and can result in mental and sensory deficits. There are some forms of bacterial meningitis are contagious, but is not spread through casual contact. According to the CDC, there are several causative agents of bacterial meningitis and each pathogen is more prevalent in different age groups. But scientists have found treatments and vaccines in hope of prevention.
Neisseria meningitidis has been around for hundreds of years and has been one of the major causes of bacterial meningitis worldwide. This non endospore forming diplococcus, aerobic, gram negative bacterial pathogen is exclusive only to humans and is a challenge worldwide. Over 500,000 cases occur each year which makes it in the top ten infectious cause of death worldwide [7]. Physical and mental side effects are often a permanent outcome for patient that survive Neisseria meningitidis. Neisseria meningitidis is located in the back of the nose or throat in around 1 to 10, which show no signs of disease transient microbiota. When a patient that carries this bacterium, but doesn 't show any signs, is know as a asymptomatic carrier.
