NEONATAL MENINGITIS
Neonatal meningitis is a life-threathening medical condition in infants. Meningitis is the inflammation of the meninges (a protective membranous layer of the central nervous system) in the neonatal period. The most common causes of neonatal meningitis is bacterial infection of the blood:
• Group B Streptococci (GBS; Streptococcus agalactiae)
• Escherichia coli
• Listeria monocytogenes.
Regardless of the specific pathogen involved, neonatal meningitis is most often caused by vertical transmission during labor and delivery. It occurs few days following birth and is more common in premature infants than in term infants.
1.0. GROUP B STREPTOCCI (GBS) CAUSING NEONATAL MENIGITIS
1.1. CHARACTERISTIC FEATURES
Group B Streptococcus (GBS or Streptococcus agalactiae) is an encapsulated gram-positive diplococcus that colonizes the gastrointestinal and genital tracts of pregnant women. GBS colonization is usually asymptomatic. It is beta-hemolytic,

TREATMENT AND CLINICAL MANAGEMENT
The only reliable way to prevent early onset neonatal menigitis currently is intrapartum antibiotic prophylaxis (IAP), administration of antibiotics to the mother during delivery. It has been proved that intravenous penicillin or ampicillin administered for ≥4 hours before delivery to GBS colonized women are very effective at preventing vertical transmission of GBS from mother to baby. Cefazolin, clindamycin, and vancomycin are used in penicillin-allergic mothers.
Neonatal mortality is declining globally. According to UNICEF, worldwide neonatal mortality rate fell by 47 per cent between 1990 and 2015 from 36 to 19 deaths per 1,000 live births. Over the same period, the number of newborn babies who died within the first 28 days of life declined from 5.1 million to 2.7
Unknown Culture Lab Report
1054 Words | 5 PagesIdentification of bacteria within Unknown Culture #21 In this experiment, an unknown culture of two different types of bacteria was assigned to each person, a number of tests were performed to isolate and identify these bacterial cells. Based on knowledge from the previous experiments completed in lab, a basic understanding of each type of bacteria was used to create a flow chart that would aid the process of identifying the unknown bacteria within the culture. A gram stain that is performed initially will narrow down the types of tests certain bacteria will and will not respond to. In addition to the gram stain, some of the tests that were used include, a catalase test, an Eosin methylene blue (EMB) agar test, a bile esculin test, and a 6.5% sodium chloride (NaCl) test.

The MacConkey agar plate and the Mannitol Salt agar plate are both used in the identification of the unknown. The MC plate is a selective and differential medium. It is considered a selective medium because the bile salts and crystal violet aspect of the medium prevent the growth of gram positive bacteria (3). This medium is differential because of the lactose and neutral red.
Lab Report Identifying Unknown Microorganisms
1596 Words | 7 PagesIn this experiment, we cultivated an unknown specimen containing two microorganisms. The purpose of this experiment was to use a variety of biochemical test previously learned in the lab to identify the unknown bacteria. The identification of unknown bacteria is a major part of microbiology. Microbiologist observe samples such as blood and sputum in the laboratory for the presence of microorganisms. Identifying unknown bacteria is extremely important in clinical settings because it helps physicians find treatment for infections.

Biochemical tests were used to help identify the unknown bacteria. The Citrate test, Urease test, Triple Sugar Iron Agar test, Voges-Proskauer test, and Methyl Red test were the biochemical tests used in this experiment.
Neonatology Career Paper
730 Words | 3 PagesThe education path to becoming a neonatologist is very tedious and intense. This includes four years of high school, a four-year college degree, four years of medical school, a pediatric internship and residency for three years, and finally a neonatology fellowship for three years. What many fail to realize is that they are not simply sitting in a classroom for the whole eighteen years. Following the second year of medical school, they get the chance to interact in a hands-on approach with patients under supervision. After graduating from medical school, an "M.D." degree is received.

The unknown bacteria was identified based on lab test results in the table provided in class for the possible unknown bacteria. The unknown bacteria identified as #36, and based on the lab tests is Enterobacter II Materials and Methods Catalase Test- this test determines whether bacteria have the enzyme catalase which catalyzes the breaks down hydrogen peroxide.
Unknown Bacteria
557 Words | 3 PagesIn the laboratory, identification of an unknown bacterium is often necessary. In the lab, a random sample consisting of three different bacteria was selected. The sample contained one gram-positive, one gram-negative paracolon, and one gram-negative coliform. The purpose of the experiment is to identify each of the three species that the mixture contained. After receiving an unknown mixture, the sample was streaked for isolation onto TSA, blood agar, and MacConkey plates.
Unknown Bacteria Report
884 Words | 4 PagesWhen given an unknown bacteria there are a multitude of steps one must go through to be able to correctly identify what bacteria was given. It is important to correctly identify the bacteria because some bacteria are more harmful than others. The gram stain is the first test that should be performed because it helps narrow down the possibilities by telling one whether the bacteria is gram positive or gram negative. After this test is performed, one shall place bacteria on/in Mannitol Salt agar, MacConkey agar, Eosin Methylene Blue agar, Urea agar, Simmon’s Citrate, Purple Beef broth with Lactose and finally Purple Beef broth with Sucrose. A streak plate should also be made up, this helps one identify the morphology of the colonies.

The terms, “neonatology and neonatologist were first introduced in 1960” (Philip 799).
Pertussis: Whooping Cough Virus
557 Words | 3 PagesAccording to the CDC, “approximately half of the babies less than one year old who get pertussis need treatment in the hospital” (Fast Facts). The pertussis vaccine, discovered in 1906 was developed by Bordet and Gengou. It is a common virus that is more well known for affecting babies. The virus also known as “Whooping Cough” for the sound the host makes while trying to catch their breath.
The Stork's Nest: Lack Of Health Care
295 Words | 2 PagesFactors such as lack of health insurance, poor living conditions, being under-educated, stress and the lack of social support can put the infants at risk for mortality. Many African Americans, especially those who are poor and those working without health care benefits, are less likely than white Americans to have a usual source of health care (Copeland, 2005). An environment a person lives in is related to health problems too. Families living in urban areas are confronted with the constant challenges of population density, inadequate or unaffordable housing, overcrowding, limited access to resources, and high crime rates (Copeland, 2005). African American families are at risk for SIDS due to the environment that the baby is discharged.
