During 2014-2015, patients in northeastern Kenya were assessed for brucellosis and characteristics that might help clinicians identify brucellosis. Among 146 confirmed brucellosis patients, 29 (20%) had negative serologic tests. No clinical feature was a good indicator of infection, which was associated with animal contact and drinking raw milk.

The development of an antigen schema for Pseudomonas aeruginosa based on challenge protection in mice as distinguished from serological tests in vitro was described. For 342 cultures, seven groups of cross-protective homogeneity were defined.

The method is as inexpensive as possible granted that an automatic fraction collector is used. The total capital cost, assuming that one is already performing HAI tests is £50. The technique has been made as simple as possible by removing all strictly unnecessary steps. Accordingly interpretation of results has been based on an appreciation of the overall pattern of HAI activity within the IgM ...

A new monoclonal antibody, CSLEX1, directed against sialylated Lewisx was tested in parallel with a monoclonal antibody, CSLEA1, directed against sialylated Lewisa antigen. In tests with a solid-phase radioimmune sandwich assay, the sialylated Lewisx monoclonal antibody detected sera from certain cancer patients that were negative with the sialylated Lewisa monoclonal antibody. Some sera from c...

To the Editor: A recent article by Zucker (1) described two cases of malaria that were probably transfusion associated. A case of transfusionassociated malaria in which the source was identified was reported in San Francisco in 1991. The case was in an elderly man in whom malaria infection developed after coronary bypass surgery. The patient was born in China and immigrated to the United States...

The study was conducted in two districts of Oromiya regional state in Arsi-Bale highlands. The data were collected on the occurrence of T.evansi infection in sheep and goats. The disease has been detected by two serological tests (CATT and LATEX) and antibodies were demonstrated against T.evansi at least in one of the examined animals in two districts: Dodolla (Danaba, Wabe, Tulualewanso and Ga...

PURPOSE Chagas disease (CD) has become a global health issue mainly due to migration. Germany lacks surveillance data and is home to a large Latin American immigrant population. Recognising that Bolivia is the country with the highest CD prevalence in Latin America, this cross-sectional, descriptive pilot study investigated CD and associated factors among citizens of Bolivian origin living in M...

A short series of biochemical and serological tests were developed for the rapid presumptive identification of "Streptococcus milleri group" isolates. One hundred and seventy seven streptococcal isolates were recovered from the mouths of 10 out of 12 healthy adult volunteers by use of a simple sampling procedure and a single selective medium. In all, 127 oral "S milleri group" isolates were ide...

For the laboratory diagnosis of Chagas disease several tests are commonly used. Sensitivity and specificity must always be taken into account, as well as the fact that these methods vary when we are dealing with an acute or chronic stage of the parasitosis. Also, it is important to remember that the initial stage of Trypanosoma cruzi infection is characterized by the presence of the parasite in...

The serology of treponemal disease has become simpler and more rational in recent years, mainly as a result of the widespread adoption of specific antibody tests and the use of monospecific fluorescent antibody procedures which give information about the immunoglobulin class of antibodies. A set of tests which has proved particularly useful in routine diagnosis is the following: quantitative TP...
