Factors influencing the spread of pertussis in households. The lack of cilia causes foreign matter to build in the lower airways, and coughing and inflammation results. Todar’s Online Textbook of Bacteriology. Aminoglycosides (gentamicin and amikacin) are the antibiotics of choice for treatment of B. bronchoseptica; however, erythromycin and tetracycline may also be effective. B. petrii is the only environmental species of this genus. Even though pertussis clinical presentation tends to be unspecific, there are some clinical features that seem to be more common in different age groups [14, 30]. These toxins include the pertussis toxin (exotoxin) that activates host cell production of cAMP to modulate cell protein synthesis regulation, a tracheal cytotoxin that causes destruction of ciliated epithelial cells, and a cell surface hemagglutinin to assist in bacterial binding to the host cells. (n.d). However, as previously noted, research indicates that the spread of pertussis follows no seasonal pattern.

Describe the prevalence of Bordetella pertussis via PCR in children under 5 years old hospitalized as probable cases of pertussis and report the most common clinical features among them.

Pertussis is thought to occur in two stages. CD4+ T cell clones that proliferate when stimulated with Ptx or FHA have been identified in peripheral blood mononuclear cells from children and adults following recovery from pertussis [207–210].
Bordetella are tiny, gram-negative coccobacilli that grow aerobically on starch-blood agar or completely synthetic media with nicotinamide supplemented for growth, amino acids for energy, and charcoal or cyclodextrin resin to absorb fatty acids and other inhibitory substances.

In rare instances, B. pertussis can be transmitted by contact with freshly contaminated particles alone. In addition, in infants younger than 3 months and neonates the increasing incidence of this infection and the sustained mortality rates have encouraged further investigation about the efficacy and safety of pertussis vaccination for pregnant women as an attempt to reduce the disease burden [18]. 2013;8(13):526.

Complications during hospitalization were also registered, pneumonia was the most frequent outcome in 33% of our study population and 38.9% of our patients with B. pertussis (Table 2). In addition, because the organism lives anchored to the epithelial surface of the airway, many foals with B. bronchoseptica pneumonia require prolonged antimicrobial administration for complete resolution of disease as a result of extensive epithelial injury by bacterial toxins and inaccessibility of the respiratory epithelium by antimicrobial agents. A positive PCR result for B. pertussis was observed in 20.5% of our samples (18/88), one-third of them were from infants between 2 and 3 months old.
