28 Nasal Catarrh Caused in Kal)l)its l)y Coccidia. 



dogs. The possibility of coiifoiindiiig the disease witli rabies 

 appears quite remote. The presence or absence of paralysis 

 is of great differential diagnostic valne; the presence of 

 Pentastomnm does, of course, not exclude the i)ossibility of 

 rabies. 



Treatment. Therapeutic interference becomes necessary 

 only in the presence of severe symptoms. Inhalations of 

 chloroform, dilute ammonia or benzine and instillations of 

 turpentine do not, as a rule, lead to satisfactory results. Tliere 

 is, therefore, nothing left when interference becomes indicated 

 but to trephine the frontal sinuses or the nasal cavities in 

 order to remove the parasites with forceps and to irrigate 

 from above with a solution of creolin or carbolic acid.

Other Parasites in the Nose. In southern countries horse leeches 

 (Haemopis sanguisnga) are sometimes found in the nose of the horse. 

 In the nasal and infra-orbital cavities of ])irds the monostoinum is 

 very rarely found. — Ulreich (Vet., 1896, 292) found parasitic ova in 

 the purulent nasal discharge of a young dog suffering from a bronchial 

 catarrh, there prolia})ly identical with those of Trichosoma aeroiihihnn. 

 found by Creplin in the trachea and bronchi of a fox, by IMiiller in 

 a badger and by Neumann in a cat. After intranasal and intratracheal 

 injection of turpentine and oil of sesame, the disease ended in recovery 

 in four weeks. 



(c) Nasal Catarrh in Rabbits Caused by Coccidia. Rhinitis 

 coccidiosa cuniculorum. 



{Psurospcruiuc, or Gregariiuc Rhinitis [Zukn].) 



After the invasion of the nose of a rabbit l,y coccidia, 

 there occurs an intense inflammation. The affection occurs 

 enzootically and usually spreads to the other mucosae of the 

 head. 



Historical. All enzootic nasal catarrhs in rabbits were formerly 

 known under the collective name of malignant coryza ("malignant 

 snuffles"), but they were all classified as coceidial rhinitis after Ziirn 

 had demonstrated the presence of coccidia. Further o])servaftions, 

 however, have shown that not all of those affections properly l)elong 

 to coceidial rhinitis (see page 15). 



Etiology. The invasion by coccidia (according to Railliet, 

 C. perf orans ; however, according to Martin, Eimeria s!
