Although such haemorrhages usually clear completely in time, they tend to accompany more serious damage to the retina, which can only be fully revealed once clearing has taken place. Retina Bruising and oedema of the retina are seen as grey areas with scattered haemorrhages. The macular region is susceptible to oedema after contusion injuries, causing permanent damage to the reading vision. Just as tears can occur to the peripheral iris, so a similar problem is seen in the peripheral retina. These crescent-shaped retinal dialyses are also most common in the lower temporal quadrant and their importance lies in the fact that they may lead to a detach- ment of the retina unless the tear is sealed by laser treatment.

The signicance of these or- ganisms is unknown, but infection apparently causes hypertrophy or thickening of the abomasum and the mucosal folds within. The same author has identied the organism by histopathology, fecal otation, and acid-fast staining of fecal smears. Papular Stomatitis Etiology A parapoxvirus indistinguishable from the virus of pseu- docowpox and also possibly related to the contagious ecthyma virus of sheep and goats is the cause of papular stomatitis in calves. The virus is quite contagious in Circular papular stomatitis lesions on the ventrum of a calf s tongue. Such zoonotic infection creates lesions similar to the milker s nodules of pseudo- cowpox in people. Some papules develop Papular stomatitis lesions caudal to the incisor teeth a necrotic white center that sloughs, leaving an ulcerated and ventral to the tongue in a calf. Papular stomatitis lesions brownish-yellow in color, slightly raised, and have may cause an affected calf to show mild salivation and rough edges. Such signs usually lead to examination of the oral cavity and subsequent diagno- sis. Calves from several weeks to several months of age are most commonly affected, but the disease has also been observed in older growing cattle. Lesions also occur in the esophagus and forestomach mucosa but are only detected in those locations during necropsy examina- tion. Severe illnesses or immunodeciencies frequently allow extensive proliferation of papular stomatitis virus and subsequent advanced lesions.

They hide in bed headboards, furniture, and mattresses, and behind wallpaper during the day and come out at night to feed on the sleeping victim in the bed. Skin tests with deer ked extract in ve patients with persistent reactions to deer ked bites showed positive delayed reactions in all patients, and immediate reactions in three patients. Penneys  studied circulating IgG antibodies to mosquito salivary gland proteins in relation to intensity of exposure to mosquitoes in 13 individuals. In those with a history of little or average exposure, antibody binding was found; in those with extensive exposure, little antibody binding was found. This seems to correlate with the skin reactions where massive exposure to mosquito 266 Imported Skin Diseases bites at an early age leads to tolerance. Jordaan and Schneider  did not nd immunoglobulin or complement deposits in their group of 30 patients. However, there are distinct stages in mosquito- and eabite immunity that have been consistently described by several authors [5,10]: 1 A 5 7 day induction phase without symptoms. After a few weeks pruritic papules or vesicles appear within a day after a fresh bite and may persist for weeks. The delayed reaction gradually fades leaving: (a) an immediate reaction only; and (b) ultimately a lack of reaction (tolerance). Children between the ages of 1 month and 7 years worldwide go through these phases as they meet insects, respond to them, and develop tolerance [11, 12]. After developing tolerance, they will respond to repeated bites in the same way as most adults.
