Particularities of preimmune reactivity in patients with pulmonary tuberculosis in combination with toxocariasis

Background For many years it was considered that bronchial obstruction is caused by a bacterial or viral infection of the respiratory system and the pathogenesis is associated with the sensitization of a bronchial tree by pathogens or non-pathogenic entities which inhabit the respiratory passages. Symptomatic pulmonary disease characteristics are present in 65% of patients with visceral toxocariasis and catarrhal symptoms vary from mild to severe asthmatic.
