Family Cluster Of Rocky Mountain Spotted Fever, James E. Childs, Timothy F. Jones, Allen S. Craig, Christopher D. Paddock, Don B. Mckechnie, Sherif R. Zaki, William Schaffner
Zoonotics and Wildlife Disease: Publications
Soon after a patient from Tennessee died of Rocky Mountain spotted fever (RMSF), several family members developed symptoms suggestive of the disease and were treated presumptively for RMSF. Fifty-four persons visiting the index patient's home were interviewed; serum samples were collected from 35. Three additional cases of RMSF were confirmed, all of which occurred in firstdegree relatives. Time spent at the family home and going into the surrounding woods were significantly associated with developing antibodies to Rickettsia rickettsii. Ticks were collected and examined for rickettsiae by polymerase chain reaction analysis. Because hyperendemic foci and family clusters of RMSF can …

Zoonotics and Wildlife Disease: Publications
A clone expressing an immunoreactive protein with an apparent molecular mass of 44 kDa was selected from an Ehrlichia chaffeensis Arkansas genomic library by probing with anti-E. chaffeensis hyperimmune mouse ascitic fluid. Nucleotide sequencing revealed an open reading frame (ORF) capable of encoding a 198-aminoacid polypeptide. The ORF contained four imperfect, direct, tandem 90-bp repeats. The nucleotide and deduced amino acid sequences did not show close homologies to entries in the molecular databases. PCR with primers whose sequences matched the sequences flanking the ORF was performed with DNA samples extracted from cell cultures infected with nine different isolates of E. …

An indirect immunofluorescence assay (IFA) was used to identify patients with antibodies reactive to the human granulocytic ehrlichiosis (HGE) agent. Serum samples collected from clinically ill individuals were submitted to the Centers for Disease Control and Prevention by physicians via state health departments from throughout the United States and tested against a panel of ehrlichial and rickettsial pathogens. Antibodies reactive to the HGE agent were detected in 142 (8.9%) of 1,602 individuals tested. There were 19 confirmed and 59 probable (n = 78) cases of HGE as defined by seroconversion or a fourfold or higher titer to the HGE agent …

Bacterial Toxins: Friends Or Foes?, Clare K. Schmitt, Karen C. Meysick, Alison D. O'Brien
Uniformed Services University of the Health Sciences
Many emerging and reemerging bacterial pathogens synthesize toxins that serve as primary virulence factors. We highlight seven bacterial toxins produced by well-established or newly emergent pathogenic microbes. These toxins, which affect eukaryotic cells by a variety of means, include Staphylococcus aureus α-toxin, Shiga toxin, cytotoxic necrotizing factor type 1, Escherichia coli heat-stable toxin, botulinum and tetanus neurotoxins, and S. aureus toxic-shock syndrome toxin. For each, we discuss the information available on its synthesis and structure, mode of action, and contribution to virulence. We also review the role certain toxins have played in unraveling signal pathways in eukaryotic cells and summarize …

Michigan Bovine Tuberculosis Bibliography and Database
An epidemiological survey for the monitoring of bovine tuberculosis transmission was carried out in western Liguria, a region in northern Italy. Fifteen Mycobacterium bovis strains were isolated from 63 wild boar samples (62 from mandibular lymph nodes and 1 from a liver specimen). Sixteen mediastinal lymph nodes of 16 head of cattle were collected, and 15 Mycobacterium bovis strains were subsequently cultured. All M. bovisstrains isolated from cattle and wild boars were genotyped by spoligotyping and by restriction fragment length polymorphism (RFLP) analysis with the IS6110 and IS1081 probes. All M. bovis strains showed the typical spoligotype characterized by …

This report describes and discusses the history, clinical, pathologic, epidemiologic, and human health aspects of an outbreak of Mycobacterium bovis infection in domestic wapiti in Alberta between 1990 and 1993, shortly after legislative changes allowing game farming. The extent and seriousness of the outbreak of M. bovis in wapiti in Alberta was not fully known at its onset. The clinical findings in the first recognized infected wapiti are presented and the postmortem records for the herd in which the animal resided are summarized. Epidemiologic findings from the subsequent field investigation are reviewed, the results of recognition and investigation of human …
A Comparison Of Wildlife Control And Cattle Vaccination As Methods For The Control Of Bovine Tuberculosis, R. R. Kao, M. G. Roberts
A Comparison Of Wildlife Control And Cattle Vaccination As Methods For The Control Of Bovine Tuberculosis, R. R. Kao, M. G. Roberts
Michigan Bovine Tuberculosis Bibliography and Database
The Australian brushtail possum is the major source of infection for new cases of bovine tuberculosis in cattle in New Zealand. Using hypothetical values for the cost of putative cattle and possum Tb vaccines, the relative efforts required to eradicate Tb in cattle using possum culling, possum vaccination or cattle vaccination are compared. For realistic assumed costs for 1080 poison bait, possum culling is found to be a cost-effective strategy compared to cattle vaccination if the required control area is below 13 ha per cattle herd, while possum vaccination is cost-effective for control areas of less than 3 ha per …
The Search For Unrecognized Pathogens, David A. Relman
The Search For Unrecognized Pathogens, David A. Relman
United States Department of Veterans Affairs: Publications
The distribution and diversity of microorganisms in the world are far greater than have been previously appreciated. Molecular, cultivation independent methods have played a key role in this insight. To what extent do humans remain ignorant of microbial diversity within the human body and the settings in which microorganisms cause human disease? In addition to implicating microbial agents in nontraditional infectious diseases, the use of methods such as broad-range polymerase chain reaction, representational difference analysis, expression library screening, and host gene expression profiling may force a reassessment of the concepts of microbial disease causation.

Portions of penis and prepuce were collected from 24 bulls with current or recent Tritrichomonas foetus infection. Epididymides were collected from seven of the bulls, and seminal vesicles and prostate were collected from four. Following immunohistochemical staining with two monoclonal antibodies (34.7C4.4 and TF1.15) prepared against T. foetus surface antigens, trichomonads were identified in sections from 15 of the bulls. Organisms were most often located in penile crypts in the midshaft and caudal regions and less often in preputial crypts. Trichomonads were not observed in sections from other genitalia or in subepithelial tissue. T. foetus antigen, however, was present in …

Characterization Of The Jembrana Disease Virus Tat Gene And The Cis- And Trans-Regulatory Elements In Its Long Terminal Repeats, Hexin Chen, Graham Wilcox, Gde Kertayadnya, Charles Wood
Nebraska Center for Virology: Faculty Publications
Jembrana disease virus (JDV) is a newly identified bovine lentivirus that is closely related to the bovine immunodeficiency virus (BIV). JDV contains a tat gene, encoded by two exons, which has potent transactivation activity. Cotransfection of the JDV tat expression plasmid with the JDV promoter chloramphenicol acetyltransferase (CAT) construct pJDV-U3R resulted in a substantial increase in the level of CAT mRNA transcribed from the JDV long terminal repeat (LTR) and a dramatic increase in the CAT protein level. Deletion analysis of the LTR sequences showed that sequences spanning nucleotides 268 to 153, including the TATA box and the predicted first …

Bacterial Growth State Distinguished By Single-Cell Protein Profiling: Does Chlorination Kill Coliforms In Municipal Effluent?, David Rockabrand, Teresa Austin, Robyn Kaiser, Paul H. Blum
School of Biological Sciences: Faculty Publications
Municipal effluent is the largest reservoir of human enteric bacteria. Its public health significance, however,
depends upon the physiological status of the wastewater bacterial community. A novel immunofluorescence
assay was developed and used to examine the bacterial growth state during wastewater disinfection. Quantitative
levels of three highly conserved cytosolic proteins (DnaK, Dps, and Fis) were determined by using
enterobacterium-specific antibody fluorochrome-coupled probes. Enterobacterial Fis homologs were abundant
in growing cells and nearly undetectable in stationary-phase cells. In contrast, enterobacterial Dps homologs
were abundant in stationary-phase cells but virtually undetectable in growing cells. The range of variation in
the abundance of …

Absence Of Tuberculosis In Free-Ranging Deer In Nebraska, David J. Steffen, David W. Oates, Mauritz C. Sterner, Vickie L. Cooper
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Lymph nodes from 271 white-tailed deer (Odocoileus virginianus) and mule deer (Odocoileus hemionus) in Nebraska (USA) were examined microscopically for tuberculoid lesions. Lymph nodes lesions in at least one node were found in 12 deer. Lesions were examined with Zeihl-Neelson acid fast stains and by polymerase chain reactions using M. bovis specific probes. No evidence of tuberculosis was found. The small granulomatous lesions were likely caused by other bacteria.

Harold W. Manter Laboratory of Parasitology: Faculty Publications
The phylogeny of nematodes in the family Protostrongylidae (Nematoda: Metastrongyloidea) was reconstructed by cladistic analysis of 28 binary and multistate characters derived from comparative morphology. Analyses were hierarchical, and examined (1) relationships among genera, including 13 ingroup taxa and Metastrongylidae as an outgroup (single tree, 78 steps, consistency index [CI]=0.705); and (2) relationships among genera and species groups including 21 ingroup taxa and Metastrongylus apri as an outgroup (single tree, 76 steps, CI=0.582). In the species-level tree, Protostrongylidae was divided into 2 major clades, one containing the subfamilies Muelleriinae (including the recently described Umingmakstrongylus pallikuukensis) Elaphostrongylinae, and the Varestrongylinae …

Revisiting The Code: Clarifying Name-Bearing Types For Photomicrographs Of Protozoa, Donald W. Duszynski
Harold W. Manter Laboratory of Parasitology: Faculty Publications
In 1988, Bandoni and Duszynski argued that individuals involved in the taxonomy and systematics of the coccidia should become familiar with the 3rd edition of the Code of Zoological Nomenclature (Ride et aI., 1985) and tried to reiterate the importance and utility of designating some form of type specimens and archiving them in appropriate museums. Their intent was to create an awareness among biologists working with coccidia (or other protists) of the value of designating type specimens. In the decade since their admonition, bench scholars working with coccidia, and journal editors to whom they submit their work, have begun …

Discovery of the ostertagiine nematode Teladorsagia boreoarcticus n. sp. in muskoxen, Ovibos moschatus, from the central Canadian Arctic highlights the paucity of knowledge about the genealogical and numerical diversity of nematode faunas characteristic of artiodactyls at high latitudes across the Holarctic. Teladorsagia boreoarcticus is a dimorphic cryptic species distinguished from Teladorsagia circumcincta/Teladorsagia trifurcata in domestic sheep by a 13% divergence in the ND4 region of mitochondrial DNA, constant differences in the synlophe, and significantly longer esophageal valve, spicules, gubernaculum, and bursa. Teladorsagia boreoarcticus represents an archaic component of the North American fauna and may have a Holarctic …

Carmovirus is one of two officially recognized genera of Tombusviridae. Members of Tombusviridae all have icosahedral virions of about 30 nm in diameter with T = 3 symmetry that consists of 180 coat protein (CP) subunits of about 38- 43 kDa and a single-stranded (ss) RNA genome ranging in size from 4.0 to 4.7 kb. Carmoviruses share recognizable sequence similarity in both the polymerase and structural genes with members of the other genus, Tombusvirus. Sequence comparisons and phylogenetic analysis of these genes support the view that the genera are distinct but closely related. In addition, the genome organization of the …
