A simple, inexpensive slide agglutination test correctly identified the serogroup to which 38 Legionella pneumophilia strains belonged, and distinguished them from two atypical, Legionella-like organisms.

This paper presents a review of Leptospira infection in farm animals in Portugal which is based mainly on serological results obtained in the National Veterinary Research Laboratory between January 1987 and December 1993. Serum samples were tested by the microscopic agglutination test, at a minimum dilution of 1:100. Positive titres were obtained in 15.3% of the 9,543 bovine samples examined. S...

A newly developed rapid coagglutination test for identifying Haemophilus influenzae type b organisms isolated from clinical specimens correlated 100% with the slide agglutination test but was 100- to 200-fold more sensitive.

Little is known concerning the seroprevalence of Toxoplasma gondii infection in goats in Mexico. Antibodies to T. gondii were determined in 562 goats in Durango, Mexico using the modified agglutination test. Goats were raised in 12 farms in two geographical regions: semi-desert (n=70) and mountains (n=492). Overall, antibodies to T. gondii were found in 174 (31%) of 562 goats, with titers of 1:...

This study reports the use of an agglutination test as a routine diagnostic aid for tuberculosis. We have found this to be both useful and reliable in clinical practice. The overall reliability was greater than 90%, 13 false results being obtained in the 222 patients tested. False negatives (4) were less common than false positives (9). The major advantage of the test is its speed, serological ...

The article presents the prevalence of Neisseria meningitidis carriage with the identification of sero- and genogroups in professional soldiers serving in the Polish Armed Forces. A total of 1246 soldiers from the 10th Armored Cavalry Brigade in Świętoszów, Poland were examined in the period January-February 2016. Microbiological tests were performed using standard methods (culture, incubation,...

BACKGROUND Long-term microscopic agglutination test (MAT) results after vaccination with 4-serovar Leptospira vaccines are not available for all vaccines used in client-owned dogs. HYPOTHESIS/OBJECTIVES To determine antibody responses of client-owned dogs given 1 of 4 commercially available Leptospira vaccines. ANIMALS Healthy client-owned dogs (n = 32) with no history of Leptospira vaccina...

The aim of the investigation was to determine the prevalence of T. gondii among a domestic cat population in an urban area in Olsztyn. In total, 135 serum samples of cats collected in several veterinary outpatient clinics in Olsztyn were examined by direct agglutination assay. The Toxo-Screen DA BioMerieux commercial test detected anti-Toxoplasma gondii IgG antibodies. The results of studies in...

It is now generally recognized that the diagnosis of enteric infection by the agglutination test requires a degree of precision, the need for which has become more apparent only within recent years. It was strongly emphasized in a previous communication (Soman, 1932) that in order to minimize the chances of errors in the diagnosis by methods of agglutination alone, a clot culture should be made...

Prevalence of antibodies to Toxoplasma gondii was determined in 203 muskoxen (Ovibos moschatus) from 3 geographically distinct areas of northern Canada (near the hamlets of Kugluktuk and Cambridge Bay, Nunavut and Holman, Northwest Territories) by the modified agglutination test (MAT). Antibodies were found in 13 (6.4%) of 203 animals with MAT titers of 1:25 in 2, 1:50 in 7, 1:200 in 2, 1:400 i...
