[Leptospirosis in swine; observations on the serological diagnosis of Leptospira interrogans serotype bratislava].

Leptospirosis is considered to be an important cause of porcine reproductive failure. In this respect recently attention is paid to the possible role of Leptospira interrogans serotype bratislava (bratislava). In the present paper the results of serotype bratislava serology conducted on three farms are presented and discussed. On two of the farms no reproductive failure was observed. On the third farm with a high percentage of return to service a longitudinal search was done. No relation could be demonstrated between bratislava titers and reproductive failure.

Differential susceptibility of two stocks of Mongolian gerbils (Meriones unguiculatus) to Leptospira.

Mongolian gerbils (Meriones unguiculatus) of Tumble Blook (TUM) and Japan Medical Science (JMS) stocks were compared with regard to susceptibility to Leptospira interrogans serovar copenhageni. The TUM gerbil died 6 to 9 d after intraperitoneal inoculation with 10 organisms, showing jaundice and systemic hemorrhage. However, 25% of the JMS gerbils survived infection with 10(3) or 10(4) organisms and there was no fatal case after infection with 10(2) organisms.

Isolation of Leptospira interrogans serovar bratislava from stillborn and weak pigs in Iowa.

Leptospira interrogans serovar bratislava was isolated from a herd of swine in Iowa with a history of stillborn and weak neonatal pigs. Placentas, kidneys, and lungs of stillborn and weak pigs from 3 litters were processed to detect leptospires by use of bacteriologic culture and fluorescent antibody testing. Sera from stillborn and weak pigs were tested to detect agglutinating antibody against leptospires. A low antibody titer against L interrogans serovar bratislava was detected in the sera of stillborn and weak pigs. Small numbers of leptospires were sometimes detected in tissues by use of the fluorescent antibody test. Serovar bratislava was isolated from placentas, stillborn pigs or weak pigs from each of the 3 litters.

[A patient with fever and pain in the extremities].

During holidays in Suriname a six year old boy fell ill with high fever, general malaise, pain in the extremities and abdomen and vomiting. Because of a tentative diagnosis of acute rheumatism or bacterial enteritis amoxicillin and salicylates were started. After his return to the Netherlands an increased ESR and impaired renal and hepatic functions were found. The history revealed contact with sewage water. Further analysis established the diagnosis of Leptospirosis. This comparatively rare clinical entity, seldom mentioned in paediatric literature, is discussed.

Dihydrostreptomycin treatment of bovine carriers of Leptospira interrogans serovar hardjo.

Ten non-pregnant heifers, experimentally infected with Leptospira interrogans serovar hardjo, were each given an intramuscular injection of dihydrostreptomycin at a dose rate of 25 mg kg-1. In five of these animals this treatment was repeated after 14 days. Treatment failed to remove established genital or renal infection in seven of the 10 heifers, although the number of organisms persisting was apparently reduced in these animals. Serovar hardjo infection persisted for at least 83 days in the oviduct and uterus and these tissues may be as important carrier sites for serovar hardjo as bovine kidney tissue.

Leptospirosis in Hawaii: shifting trends in exposure, 1907-1984.

Leptospirosis was first recognized as an occupational disease of sugar plantation workers in Hawaii in 1907. Since then, shifts have been noted in the animal transmission cycles, the occupational groups at risk, and an increasing recognition of cases associated with avocational exposure. Surveys of the small mammal populations indicate rats, mice, and mongooses are the most important vectors in Hawaii. Serologic surveys of workers in high-risk occupations show antibody prevalence rates ranging from 12 to 82 percent. The epidemiology of leptospirosis in Hawaii is described, based on 182 cases reported to the Hawaii Department of Health from 1970-1984. The most common infecting serovar was mankarso in the Icterohaemorrhagiae serogroup; other serovars in the Icterohaemorrhagiae group were also frequently implicated as causing disease. The manifestations of disease noted by physicians in Hawaii are similar to those observed in the continental U.S. Fever, myalgia, and headache were the most common symptoms reported in the majority of cases in Hawaii; jaundice was noted in the records of 24 percent. Recommendations made to interrupt the cycle of transmission and reduce the chances of exposure in occupational settings include the control of rodent populations and vaccination of domestic animals. Personal hygiene among workers is to be encouraged, and the development of prophylactic measures is suggested either by immunization or by chemoprophylaxis.

The isolation of Leptospira interrogans serovar pomona and related serological findings associated with a mixed farming unit in the Transvaal.

This is the first known isolation in the Republic of South Africa (RSA) of the serovar pomona from the organs of porcine foetuses as well as from the renal lymph nodes of slaughter pigs showing chronic nephritis. In addition, the serovar pomona was isolated from the kidneys of 87.5% of the slaughter pigs examined. The success of these isolations was attributed in part to the refining of 2 existing isolation techniques which complement each other. Using the microscopic agglutination test, serum samples taken from the same farming unit showed evidence of antibodies to the serovar pomona in 89 out of the 170 bovines (52%), 9 out of the 52 porcines (17%), 2 of the 2 canines (100%), 5 out of the 13 equines (38%) and 2 out of the 152 ovines (1%) that were tested. As far as is known, serological evidence of the serovar pomona in porcines, ovines, equines and canines has never previously been published in the RSA.
