In two experiments, 8 Hamsters inoculated with material from yaws lesions (Treponema pertenue), developed skin lesions considered specific by their clinical and histopathological aspects and by the presence of treponemae. These lesions appeared on the scrotumm, testicle, prepuce, anus, tail, muzzle, back and hinders paws (palm surface). In the internal organs no treponemae were found in direct examinations and inoculation of brain, spleen and lymph node. The incubation period was of 35 days for the testicle, 55 days for the scrotum and 107 days for peritoneal cavity inoculation. Positive sub-inoculations were obtained. The serum reactions (Qasserman's and Kahn's) were negative in all 5 tested Hamsters. Out of 4 normal females matched to infected males two developed nasal lesions resulting from direct contact. Apparently the genital lesions hindered copulation. Hamsters are very well suited for an experimental study of yaws.

Fetal membrane and tissue culture suspensions of the coccobacilliform bodies are infective for normal fowl. Intranasal injection is commonly followed by a coryza which is serially transmissible and communicable by direct contact. The specific bodies are generally demonstrable in the nasal exudate of birds infected either by injection or contact. Compared with the original strain of the coryza of slow onset the reaction produced by these suspensions is often less vigorous; the incidence of apparent cases, characterized by a nasal discharge, being 97 per cent and 53 per cent, respectively. The apparent cases are similarly characterized by a long incubation period and a tendency towards chronicity.

Abstract Intensive leukopheresis has been valuable in the short-term palliation of chronic lymphocytic and granulocytic leukemias. A 47-yr-old man with refractory leukemic reticuloendotheliosis (hairy cell leukemia) manifested by anemia, thrombocytopenia, elevated peripheral leukemia cell counts, generalized lymph node enlargement, and leukemic infiltrative skin disease was treated with serial leukopheresis. Removal of approximately 7 X 10(11) peripheral leukemia cells resulted in marked clinical and hematologic improvement with resolution of enlarged lymph nodes and clearing of skin infiltrates. At the time of this reporting, more than 400 wk since the last leukopheresis, the patient continues to do well. The improvement in all blood counts, reduction in lymph node size, and clearing of skin lesions paralleled the reduction of peripheral leukemia cell load by leukopheresis, suggesting mobilization of leukemia cells from marrow, lymph nodes, and skin. Removal of large numbers of leukemia cells in hairy cell leukemia has the potential of achieving sustained clinical improvement and may be a useful alternative therapy for these patients.

The investigations carried out on a sample of 53 breeders (31 females and 22 males), in a fishing farm of Suatu village, County of Cluj, concerning the incidence of hemorrhagic bacterial septicaemia, diagnosis and profilactico-therapeutic possibilities. Results highlights a incidence of bacteriosis differentiated according to the category of breeders, 54.8% in females and 36.3% in males. Necropsy examination carried out on 3 specimen of suspected bacteriosis, highlights the presence of hemorrhagic skin lesions, which are dotted or diffuse, respectively musculo-cutaneous necrosis and ulcers. Regarding the internal injuries, opening of the body cavity, revealed consistency changes and septicemy form in major internal organs, as well as the presence of a liquid hollow looking sanguinolent.The bacterioscopic examination of smears from the pathologic material (skin surface end internal samples) and colored with the Gram method, reveled bacterial microflora, represented by coccobacillus and straight bacilli or slightly curved, both Gram negative. Furthermore, the bacteriological (culture) exam performed on usual and selective culture mediae, distinguishes the isolation of pure culture bacteriae belonging to the genus Aeromonas. The exam of biochemical traits, with the aid of API 20 E multitest determines that the isolated strains of Aeromonas spp. belong to the species Aeromonas hydrophila, indicted in the emergence and evolution of the bacterial of haemorrhagic septicaemia. Testing strains sensitivity to antibiotics and chemotherapy (through antibiograma level), reflects the isolated bacteria’s values of sensitivity in decreasing order: amoxicillin, oxytetracycline, florfenicol and enrofloxacilin. However, reduced sensitivity was recorded to tetracycline and ampicillin and resistance to erythromycin.
