Bordetella

Pertussis is a disease that is considered as highly communicable and preventable through vaccine that could take for a longer period of time. It mostly manifests in children with paroxysmal spasms of frequent or severe coughing, whooping, and posttusive vomiting as well. Taking a closer look under a compound binocular microscope, “Bordetella pertussis” is viewed as a gram-negative coccobacillus and considered as a whooping cough bacterium. Complications are most common especially on infants and young children, in which it includes hypoxia, apnea, pneumonia, seizures, encephalopathy and malnutrition. The said disease is considered to be a deadly one among infants as mentioned and children too for it is actually an endemic illness. The most recent epidemic occurred in the late 1990’s in which adolescents and adults were reported to have an increase in such cases of pertusis.

Children who are very much young to be fully vaccinated and those who have not completed the primary vaccination series are reported to be at high risk for severe illness. Somewhat like measles, pertussis is actually a highly contagious developing clinical disease following exposure to an index case. Adolescents and adults become susceptible in this disease when immunity wanes.

Pertusis is considered to be one among all other diseases that are transmittable, wherein it occurs through direct contact particularly with discharges in respiratory mucous membranes of the infected person. According to experts, the sputum of an infected person determines the resistance of the Bordetella pertussis to the antigens. Bordetella pertussis on the other hand can be cultured on modified blood-free medium, as studied, wherein this method uses a compound binocular microscope, charcoal-horseblood agar, grown in supplement Stainer-Scholte broth. Infections on Bordetella can also be detected through PCR. Circulating antibodies are said to appear in three week of illness and the longest is on the eight to tenth week. An enzyme link immunosorbent assay can demonstrate antibodies and detection of IgA to be specific provides evidence of natural infection.

Pertusis is reported to have an increase in cases year every year and the usual treatment of the antibiotic erythromycin are somehow not capable in curing some of the cases of the said disease but only reduces the infection period. Experts promote inactivated whole-cell vaccines to be more effective than the oral medication of erythromycin, but do sometimes cause toxic side effects. License for booster vaccination on this disease has been released and taken possibility to be a license for primary vaccination.

The symptoms of Bordetella pertussis includes an acute respiratory infection and severe spasmodic coughing episodes during paroxysmal phase. During third phase of illness, Leukocytosis with lymphocytosis is discovered to be common. Bronchopneumonia and acute encephatolopathy are considered to be a dangerous complication and bordatella pertusis can cause milder form of pertussis.

Bordatella pertusis can be diagnosed when the sputum of an infected person is viewed under a compound binocular microscope. According to the microscopic view of such disease, the bordatellae are tiny, gram negative, aerobic coccobacilli that produces a mass of virulence factors which includes pertussis toxins, adenylate cyclase toxin, filamentous hemagglutinin and hemolysin.
