Haemorrhagic pneumonitis: A rare presentation of leptospirosis.

Leptospirosis is an uncommon zoonosis. As a systemic disease, it presents itself by multisystem involvement. Pulmonary involvement with leptospirosis often is manifested by respiratory symptoms; but pneumonia commonly is not a prominent clinical manifestation of the illness. We report a case of leptospiral pneumonia in which pulmonary manifestations were primary clinical features of the illness. The prompt resolution of chest x-ray on institution of treatment is noteworthy.

[An evaluation of the ELISA-IgM test in the early diagnosis of human leptospirosis].

Thirty-seven sera samples from patients with leptospirosis icterohaemorrhagic form were studied with a time interval of 2 to 12 days between the beginning of the symptoms and the collection blood samples. It was isolated leptospira of 5 patients' hemocultures (13.5%) and from 4 of these the etiological agent pertained to the serogroup Icterohaemorrhagiae serovar copenhageni. Thirty-five of them (94.6%), including the four patients whose the etiological agent was isolated, showed reactivity in the enzyme linked immunosorbent (ELISA) IgM test. By this way, it was demonstrated that this test is important for a rapid diagnosis of human leptospirosis, even in the beginning of the disease, when there is still leptospiraemic phase.

[The identification of Leptospira strains of different origins].

Leptospirosis is at present an ever-increasing problem in human and animal health. By means of the Korthof medium, 43 Leptospira strains were isolated from samples of human blood, water and soil. For their identification the microagglutination technique was used. The strains corresponded to the species Leptospira biflexa and Leptospira interrogans.

Seroprevalence and risk factors associated with leptospirosis in dogs.

This study was done to determine the seroprevalence and risk factors of leptospirosis in dogs. From March to September 2004, a total of 210 dogs were randomly selected from the Small Animal Hospital, Faculty of Veterinary Medicine, Chiang Mai University. Dog sera were collected from the cephalic vein and kept at -20 degrees C until submitted to the National Institute of Health for a Microscopic Agglutination Test (MAT). Risk factors were analysed using logistic regression modelling. The prevalence of Leptospira antibodies was 11% (23/210). The most prevalent Leptospira serogroups were Bataviae 5.2% (11/210), Canicola 2.4% (5/210), Australis 1.4% (3/210), Icterohaemorrhagiae 1.4% (3/210), Ballum 0.5% (1/210), Djasiman 0.5% (1/210), Javanica 0.5% (1/ 210), Mini 0.5% (1/210), and Sejroe 0.5% (1/210). Risk factors, including signalment, environment and health status, were not significantly associated with leptospirosis antibodies. However, playing in sewage, staying outdoors >50% of the time, and consumption raw meat increased the risk of leptospirosis antibodies in dogs.

[The mechanisms maintaining epidemic foci of leptospirosis].

24,419 samples of blood serum, collected in the Azerbaijan SSR among different professional groups of the population, have been tested for leptospirosis. The comparison of the results with those obtained in the natural foci of leptospirosis and in the foci of this infection appearing as a consequence of human activities has made it possible to come to the conclusion that the epidemic foci of leptospirosis are maintained due to the existence of foci among cattle. The cases of contamination among persons professionally linked with large cattle breeding complexes have been found to exceed those among persons working at farms of a nonindustrial type.

[Leptospirosis in children: a not infrequent disease (author's transl)].

A total of 14 cases of leptospirosis in children aged from 5 to 15 years, hospitalized in the Paris region, are reported. The polymorphe character of the disease is pointed out. The necessity for respecting a rigorous chronological order when requesting complementary examinations, which could confirm the diagnosis, is stressed. Domestic animals, team-mates, and while swimming at week-ends or during holidays, are potential sources or means of infection in the young. This justifies searching for leptospirosis in cases of unexplained fever, a pseudo-influenza syndrome, a meningitis which is mainly of the lymphocytic type, or more rarely, in cases of jaundice. Leptospirosis should be a disease well-known by the pediatrician.

[Use of microcapsular leptospiral antigens for detecting specific antibodies].

The sensitivity of microcapsular leptospiral antigens, produced by Japan Lyophilization Laboratory and intended for use in tests for the detection of antibodies to leptospires in the sera of experimentally immunized laboratory animals, were studied. The comparative study of the microcapsular agglutination (MCA) test and other serological tests, such as the microagglutination (MA) test and the indirect enzyme immunoassay (EIA), was made. The leptospiral antigens under study were found to actively react with serospecific and group-specific antibodies. In infected guinea pigs and rabbits specific antibodies could be detected from days 3-4 in the MCA test and only from days 5-7 in the MA test. The average antibody level determined by titration in the MCA test was 3.3 times higher and in indirect EIA, 4.3 times higher than that determined by titration in the MA test. These data make it possible to recommend the use of microcapsular leptospiral antigens for the early diagnosis of leptospirosis.
