Detection of Crimean-congo hemorrhagic fever virus antibodies in man and in animals

Crimean-Congo hemorrhagic fever [CCHF] virus antibody survey was carried out in saudi Arabia on sera from man and several animal species using the reversed passive hemagglutination inhibittion [RPHI] test. Antibodies were found in 3/354 humans, 88/2162 sheep, 14/432 goats and 1/182 cattle. Camels and horses sera gave negative result. For the sake of comparison RPHI-positive sera and some selected negative sera were tested by indirect immunofluorescence [IF] and immunodiffusion [ID]. The results revealed that RPHI test is more sensitive than either of the two tests

Cervical mycobacterial lymphadenitis

Cervical lymphadenopathy may arise from infections with mycobacteria other than mycobacterial tuberculosis. These infections are being diagnosed more frequently, and reported to be an important cause of cervicofacial lymphadenitis in Western countries and United states. These infections resemble mycobacterial tuberculosis in its clinical picture, but it is important to make a distinction between them, for their clinical courses and treatments, are different. This work discussed the differential diagnosis of mycobacterial lymphadenitis and illusterated five cases of non tuberculous mycobacteria out of forty three cases examined, and showed that tuberculosis still having a higher incidence among our patients
