[Clinical signs and differential diagnosis of foot and mouth disease in pigs].

FMD in pigs is primarily a foot disease. It is dominated by rather painful formation of vesicles in the epidermis of the feet (coronary band, interdigital clefts, bulbs) combined with severe lameness. Complications will be seen as detachment of the hoof and secondary infection of disrupted aphthae which may cause purulent arthritis of the pedal joint.

[Status of swine flu in livestock trading law].

In contrast to the opinion found in current textbooks, ferkelgrippe (also called enzootic pneumonia or mycoplasmal pneumonia) is to be considered part of the legal deficit known as "swine fever (including hog cholera)" in the Imperial Order of 1899. Modern diagnostic procedures make it possible to successfully rule out or confirm suspected cases of this legal deficit. The diagnostic certainly made possible by PCR and ELISA procedures could give new impetus to efforts to reform stock-trading law.

Differentiation of porcine Eimeria spp. by morphologic algorithms.

Oocysts of Eimeria spp. were isolated from feces of naturally infected sows by conventional flotation. Saturated sodium chloride solution was superior to zinc chloride, zinc chloride/sodium chloride or sugar solution to isolate oocysts.

[Investigations on clinical diagnosis and pathogenesis of otitis media et interna in swine].

A total of 25 pigs with a head tilt as clinical sign of otitis media et interna were examined. The majority were weaner-pigs with respiratory tract disorders. In lateral and ventrodorsal radiographic views of the bulla tympanica, there was an increased opacity, often accompanied by marginal destruction or thickening of the bulla wall.
