This predominance was more evident among patients with B. pertussis in which 27.8% (5/18) of their mother were also positive for the bacteria (Table 1).

Bordetella species interact with their mammalian hosts primarily, and perhaps exclusively, at respiratory surfaces. Suppression of T-Lymphocyte Activation and Chemotaxis by the Adenylate Cyclase Toxin of Bordetella pertussis. PCR conditions for B. pertussis were 95 °C for 10 s, 60 cycles of 5 s at 95 °C, 5 s at 57 °C and 30 s at 72 °C.

It was recently detected that patients with sickle cell disease are at an increased risk for infection with Bordetella holmesii, a recently discovered bacterium. The large amount of NO that is produced then diffuses into the ciliated epithelial cells, causing mitochondrial bloating, membrane blebbing, and extrusion from the mucosal surface. It has been assumed that this immunity is antibody-mediated, and vaccination strategies have been focused on the induction of anti-Bordetella antibodies. Google Scholar.

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 addition, 83% (15/18) of our patients with B. pertussis received antibiotic on day 1 of hospitalization, the same day we enrolled them but before we sampled and reported our results. A cross-sectional study was conducted in Cajamarca in coordination with the “Dirección Regional de Salud de Cajamarca, Peru”.

Pertussis re-emergence in the post-vaccination era. Recovery from pertussis in humans corresponds to the development of long-lasting protection against subsequent disease [215]. Experiments using immunodeficient mice also revealed the importance of adaptive immunity in controlling Bordetella infections. This proportion of positive samples is slightly lower than a previous study we conducted in 2015, where 38.4% of probable cases for pertussis were also positive for the bacteria [27]. Worldwide, around 30 million cases of pertussis and 160,000 deaths in children younger than 5 years old are registered every year, 90% of them occurring in developing countries [4,5,6].
