Ehrlichiosis -- Case studies
Abstract

Doctors report four cases of human ehrlichiosis caused by Ehrlichia ewingii. Ehrlichiosis is a tick-borne disease that affects humans, dogs, horses, deer and rodents. So far, only four species of Ehrlicia have been found in humans: chaffeensis, sennetsu, canis and an unidentified species related to equi and phagocytophila. The polymerase chain reaction confirmed that the DNA found in white blood cells from these patients belonged to Ehrlichia ewingii, a species normally found in dogs. All four patients were treated with doxycycline and all recovered.

45. Herpes Simplex Virus Type 2 Meningitis in the Absence of Genital Lesions: Improved Recognition with Use of the Polymerase Chain Reaction.

Author

Schlesinger, Yechiel, Tebas, Pablo, Gaudreault-Keener, Monique, Buller, Richard S., and Storch, Gregory A.

Abstract

Herpes simplex virus type 2 (HSV-2) is known to cause aseptic meningitis, which can be recurrent. The diagnosis of HSV-2 infection is suggested when meningitis occurs simultaneously with genital lesions but may be obscure if genital lesions are not present or are not appreciated. Viral culture of the CSF is sometimes positive, but it may also be negative, especially in cases of recurrent disease. We report three cases of HSV meningitis in young women who did not have a history of genital herpetic lesions and for whom genital lesions were not noted on presentation. With use of the polymerase chain reaction (PCR), HSV DNA was detected in CSF from all three patients. The diagnosis of HSV meningitis was further confirmed by a positive culture of CSF in one patient's case and by demonstration of intrathecal synthesis of HSV antibodies in a second patient's case. The use of PCR can improve the recognition of HSV meningitis in adults presenting with aseptic meningitis, even in the absence of herpetic lesions. [ABSTRACT FROM PUBLISHER]

46. Blinded Comparison of Repetitive-Sequence PCR and Multilocus Sequence Typing for Genotyping Methicillin-Resistant Staphylococcus aureusIsolates from a Children's Hospital in St. Louis, Missouri

Abstract

ABSTRACTWe performed a blinded study to compare repetitive-sequence PCR and multilocus sequence typing for genotyping hospital- and community-acquired methicillin-resistant Staphylococcus aureus(MRSA). The MRSA strains that were sequence type 8 (ST8), staphylococcal cassette chromosome mec(SCCmec) type IV, and Panton-Valentine leukocidin-positive clustered separately from those that were ST5 and SCCmectype II.

47. Identification of a p28Gene in Ehrlichia ewingii: Evaluation of Gene for Use as a Target for a Species-Specific PCR Diagnostic Assay

Author

Gusa, Asiya A., Buller, Richard S., Storch, Gregory A., Huycke, Mark M., Machado, Linda J., Slater, Leonard N., Stockham, Steven L., and Massung, Robert F.

Abstract

ABSTRACTPCR was used to amplify a 537-bp region of an Ehrlichia ewingiigene encoding a homologue of the 28-kDa major antigenic protein (P28) of Ehrlichia chaffeensis. The E. ewingii p28gene homologue was amplified from DNA extracted from whole blood obtained from four humans and one canine with confirmed cases of infection. Sequencing of the PCR products (505 bp) revealed a partial gene with homology to outer membrane protein genes from Ehrlichiaand Cowdriaspp.:p30of Ehrlichia canis(=71.3%),p28of E. chaffeensis(=68.3%), andmap1of Cowdria ruminantium(67.3%). The peptide sequence of the E. ewingiipartial gene product was deduced (168 amino acids) and the antigenicity profile was analyzed, revealing a hydrophilic protein with =69.1% identity to P28 of E. chaffeensis, =67.3% identity to P30 of E. canis, and =63.1% identity to MAP1 of C. ruminantium. Primers were selected from the E. ewingii p28sequence and used to develop a species-specific PCR diagnostic assay. The p28PCR assay amplified the expected 215-bp product from DNA that was extracted from EDTA-treated blood from each of the confirmed E. ewingiiinfections that were available. The assay did not produce PCR products with DNA extracted from E. chaffeensis-, E. canis-, or E. phagocytophila-infected samples, confirming the specificity of the p28assay forE. ewingii. The sensitivity of the E. ewingii-specific PCR assay was evaluated and determined to detect as few as 38 copies of the p28gene.

48. PCR Amplification and Phylogenetic Analysis ofgroESLOperon Sequences from Ehrlichia ewingiiand Ehrlichia muris

Author

Sumner, John W., Storch, Gregory A., Buller, Richard S., Liddell, Allison M., Stockham, Steven L., Rikihisa, Yasuko, Messenger, Sharon, and Paddock, Christopher D.

Abstract

ABSTRACTBroad-range PCR primers were used to amplify part of thegroESLoperon of the canine pathogen Ehrlichia ewingii, recently recognized as a human pathogen, and the murine pathogen Ehrlichia muris. Phylogenetic analysis supported the relationships among Ehrlichiaspecies previously determined by comparison of 16S rRNA gene sequences. These sequences provide additional PCR targets for species for which few gene sequences have been determined.

49. Effect of the Today Contraceptive Sponge on Growth and Toxic Shock Syndrome Toxin1 Production by Staphylococcus aureus

Author

REMINGTON, KATHRYN MARTIN, BULLER, RICHARD S., and KELLY, JUDITH R.

Abstract

Toxic-shock syndrome toxin-1 (TSST-1)-producing Stayliylococcirsatireus MN8 was grown in dialyzed beef heart infusion broth, or dialyzed beef heart infusion broth supplemented with 5 human blood or with 5 human semen, in the presence and absence of Today contraceptive sponges. Early growth of the organism was inhibited by the presence of the sponges in aerobic, static aerobic, and anaerobic cultures. In aerobic cultures that contained the sponge, minimal TSST-1 was detected by immunodiffusion assay, whereas in control cultures that did not contain the sponge, extensive toxin production was seen. In static and anaerobic cultures, the presence of the contraceptive sponge resulted in toxin levels less than or equal to the low levels seen in control cultures. These results suggest that Today cantraceptive sponges may inhibit TSST-1 production by S aureus.

50. Detection of Ehrlichiaspp. in the Blood of Wild White-Tailed Deer in Missouri by PCR Assay and Serologic Analysis

Author

Arens, Max Q., Liddell, Allison M., Buening, Gerald, Gaudreault-Keener, Monique, Sumner, John W., Comer, James A., Buller, Richard S., and Storch, Gregory A.

Abstract

ABSTRACTBlood samples collected from wild deer in Missouri in November of 2000 and 2001 were positive by PCR assays for Ehrlichiachaffeensis(50 of 217; 23%), Ehrlichiaewingii(44 of 217; 20%), and Anaplasmaspecies (214 of 217; 99%). Nucleotide sequences of selected amplicons from the assay for anaplasma matched sequences of the white-tailed deer agent. Serologic analysis of 112 deer sampled in 2000 showed a very high prevalence of antibodies to E. chaffeensis(97 of 112; 87%) and a low prevalence of antibodies reactive with Anaplasmaphagocytophila(2 of 112; 2%).
