Spatial patterns of the Citrus leprosis virus and its associated mite vector in systems without intervention [PDF]

open access: yesPlant Pathology, 2019
Leprosis is caused by the Citrus leprosis virus cytoplasmic type and is vectored by the mite Brevipalpus yothersi. Miticide applications, which cost $54 million annually, are based on inspection for the presence of mites. The aim of the present study was

Leprosy

Clinics in Dermatology, 2007
Leprosy is a granulomatous disease affecting the skin and nerves caused by Mycobacterium leprae. It continues to be a significant public health problem. Despite multidrug therapy, immunologic reactions continue to occur, leading to disability and deformity due to neuropathy. It is important that dermatologists are aware of the neurologic as well as the

The Lancet, 2004
Leprosy remains an important health problem worldwide. The disease is caused by a chronic granulomatous infection of the skin and peripheral nerves with Mycobacterium leprae. The clinical range from tuberculoid to lepromatous leprosy is a result of variation in the cellular immune response to the mycobacterium.

Current Opinion in Neurology, 2000
Leprosy is a unique infectious disease with a prolonged incubation period and a predilection for skin and nerves. The involvement of nerves by the primary infection as well as the immunologically mediated reversal reactions result in impairment of nerve function and severe disabilities.

Mast cells in leprosy and leprosy reaction

International Journal of Dermatology, 2000
AbstractBackground Mast cells can be visualized in routine, acid‐fast‐staining, paraffin tissue section as metachromatic staining cells, and can be activated to release inflammatory mediators which play a role in the cell‐mediated immune response. Methods Skin biopsy tissues were taken from the most active skin lesion of each leprosy patient at the ...

The Immunology of Leprosy: Speculations on the Leprosy Spectrum

Clinical Infectious Diseases, 1981
Leprosy is a chronic infectious disease caused by Mycobacterium leprae. The disease presents a wide spectrum of clinical manifestations, ranging from lepromatous to tuberculoid leprosy; each form may be punctuated by episodes of acute exacerbation, called reactional states.
