Bordetella pertussis is an aerobic, Gram-negative, coccobacillus bacterium. It is non-spore forming and non-motile, usually containing a capsule. Its preferred temperature to grow is in the range of 35-37C. Under the microscope, it is identified by its rod like cell shape, as well as its short, oval size. During a blood agar culture test for this particular bacteria, the specimen tends to take 3 to 6 days to form a pinpoint sized colony. B. pertussis appears to only affect the human species, therefore
course. A variety of genetic aberrations can drive the leukaemia and also initiate the transformation into high grade malignancy. Diagnosis of CLL is usually straight forward. Most cases are usually suspected by the presence of peripheral blood lymphocytosis of small mature lymphocytes with scant cytoplasm. Smear cells are typically feature of the leukaemic cells due to increased cellular fragility. International Workshop on Chronic Lymphocytic Leukaemia criteria for diagnosis require >5x10^9/L of
Life After Mono Merriam-Webster defines mononucleosis as: "an acute infectious disease associated with Epstein-Barr virus (EBV) and characterized by fever, swelling of lymph nodes, and lymphocytosis."1 It is more commonly called "mono," or "the kissing disease." When I was thirteen, I caught this dreaded disease, and it changed the ways I acted around my friends forever. Before I got sick, I never paid attention to my actions. If I was thirsty, I asked any friend for a sip of his/her drink
Complete Blood Count with Differential is one of the most commonly ordered tests for routine check-ups and/or physicals. A complete blood count with differential measures the levels of red blood cells, white blood cells, platelet levels, hemoglobin and hematocrit. Most of the time it is ordered as a screening test to check for anemia or infection. The Complete Blood Count with Differential is used to aid in diagnosing and treating a large number of conditions (Lockwood, 2013). The Complete Blood
Mononucleosis Mononucleosis is a disease caused by the Epstein-Barr virus (EBV), which is a member of the herpes family. The herpes family also includes viruses that cause cold sores, chicken pox, genital herpes, and birth defects (7). Mono, short for mononucleosis (3) "gets its name from the fact that it causes a person's white blood cells to become distorted, so that they have only one nucleus (becoming mononuclear) instead of the usual divided nucleus.'; (3) The first accounts of mono
Infectious Mononucleosis Infectious mononucleosis (colloquially known as mono) is frequently called the kissing disease. The virus that causes mono is called Epstein-Barr virus (EBV), which is one of the multiple human herpes viruses that are carried asymptomatically by most people. Primary infection is particularly usual in childhood and establishes a lifelong carrier state where the virus remains latent. The EBV replicates frequently in the oropharyngeal epithelial cells and circulating B-lymphocytes
cause is unknown, there is no way to prevent CLL. One recent study has identified skewed kappa-lambda free light chain ratio up to nine years prior to the onset of CLL. The National Institutes of Health has established that monoclonal B-cell lymphocytosis results in higher risk of developing CLL. 95% of the genetic mutations resulting in CLL are in B-cells. The other 5% are in T- or NK-cells. These mutations result in abnormal lymphocytes (leukemic cells). As the cancer progresses from the blood
