Pathology of aspergillosis-especially on systemic aspergillosis

Pathology of allergic bronchopulmonary aspergillosis.

Allergic bronchopulmonary aspergillosis (ABPA) occurs in patients with asthma and cystic fibrosis when Aspergillus fumigatus spores are inhaled and grow in bronchial mucus as hyphae. Chronic colonization of Aspergillus fumigatus and host's genetically determined immunological response lead to ABPA. In most cases, lung biopsy is not necessary because the diagnosis is made on clinical, serologic,...

Mycotoxicoses in veterinary medicine: Aspergillosis and penicilliosis

Molds and mycotoxins are contaminants of animal feed causing spoilage and clinical intoxication. Animal exposure to mycotoxins reflects diet composition with major differences occurring between animals kept predominantly of pastures, i.e. ruminants and horses, and those consuming formulated feed like pigs and poultry. Mixed feeds are composed of several ingredients, often sourced from different...

Resistance of MBL gene-knockout mice to experimental systemic aspergillosis.

Mannose binding lectin (MBL) is a protein of the collectin family that appears important in resistance to invasive pulmonary aspergillosis. We assessed the role of MBL in experimental systemic aspergillosis. MBL-sufficient C57BL/6 (WT) mice and B6.129S4--Mb11(tm1Kata) Mb12(tm1Kata)/J MBL A and C gene-knockout (KO) mice were infected intravenously with different inocula of Aspergillus fumigatus ...

Pulmonary aspergillosis.

As the population of patients with prolonged neutropenia, those receiving hematopoietic stem cell transplantation or lung transplantation, or those with human immunodeficiency virus or acquired immunodeficiency syndrome continues to increase, the rising incidence of pulmonary aspergillosis is unlikely to diminish. Aspergillus species are ubiquitous in nature, have no geographic predilection, an...
