Bacillary White Diarrhœa. De Bacillaire Witte Diarrhe of Witte Afgang der Kuikens. Dr. G. Vandevelde-Vlaamsch-Diergeneeskundig Tjdschrift, 1933, p. 57.Summary:The pullorin- or wattle-test, in its present state of development, cannot be commended for eradication of pullorin disease from poultry flocks. This, according to our own experiments and those of several investigators and laboratory-workers in B. W. D. control. The pullorin reactions don't check with the bacteriological and post-;mortem findings. The only accurate, reliable and suitable methods for the research of the infected birds are the seroagglutination and the whole blood rapid test. The two methods are of similar scientific value.

Potomac horse fever was reproduced in 15 ponies by transfusion of whole blood originally from two natural cases and subsequently from ponies infected by the transfusions. Incubation periods varied from 9 to 15 days. Affected ponies developed varying degrees of fever, diarrhea, anorexia, depression, and leukopenia. Eleven affected ponies were killed, three died in the acute phase of the disease, and one did not show clinical signs. The most consistent post-mortem findings were fluid contents in the cecum and large colon, and areas of hyperemia (of inconstant degree and distribution) in mucosae of both small and large intestines. Multifocal areas of necrosis occurred in mucous membranes. Ehrlichial organisms were most common in the cytoplasm of epithelial cells, macrophages, and mast cells of the large colon.

Intersexuality is a reproductive pathology that has been described in wild animals in recent years. However, its occurrence and consequences remain obscure and therefore all aspects of this reproductive disorder deserve attention. The aim of this study is to report a case of intersexuality with probable absence of gonadal tissue in the crab-eating fox (Cerdocyon thous) native to Brazil. The animal has male external genitalia, but its prepuce and penis were both hypoplastic. Because of a clinical suspicion of bilateral cryptorchidism, a laparotomy was performed and the absence of prostate and gonads were revealed. The procedure also revealed vas deferentia, extending laterally from the each side of the bladder basis to the right and left abdominal wall muscles. The animal died one month later, and post mortem examination confirmed the absence of prostatic and gonadal tissues. Muscular structures similar to uterine horns and cervix were founded macroscopically and confirmed by optic microscopy. In addition, post mortem findings corroborate with penis hypoplasia, since penile bone presence was observed. The vasa deferentia had a normal tissue structure, although hypoplastic. In conclusion, the case of a crab-eating fox (Cerdocyon thous) reported here represents a proved intersexual animal with probable absence of gonadal tissue.

Data are presented on 4,429 birds, comprising eight flocks, which were tested for pullorum disease by the whole blood agglutination test and the rapid serum agglutination test (commercial laboratory). The diagnoses agreed in the cases of 4,046 birds (97.24%) and disagreed in the cases of 122 birds (2.75%).Of the 122 birds, 43 were diagnosed as positive by the whole blood agglutination test and as negative by the rapid serum agglutination test, while 79 were diagnosed as positive by the rapid serum agglutination test and as negative by the whole blood agglutination test.Of the 122 birds, 102 were retested by the whole blood, rapid serum (Laboratory 1), and rapid serum agglutination test (Laboratory 2, (Experiment Station Laboratory)).There was a closer agreement between the diagnoses made on the basis of the whole blood and rapid serum tests (Laboratory 2) than between those made on the basis of the rapid serum (Laboratory 1) and rapid serum (Laboratory 2) tests (71.56% and 62.37% respectively).A detailed study of the retests and post-mortem examination of the 102 birds is presented.
