Common Parasites, Diseases And Injuries Of Freshwater Fishes In The Northwest Territories And Nunavut, D. B. Stewart, L. M. J. Bernier Jan 1999

Common Parasites, Diseases And Injuries Of Freshwater Fishes In The Northwest Territories And Nunavut, D. B. Stewart, L. M. J. Bernier

Zoonotics and Wildlife Disease: Publications

This booklet gives basic information on common parasites, diseases and injuries of fish harvested from fresh water in the Northwest Territories and Nunavut (Canada). It answers some of the more common questions asked by Aboriginal, domestic, sport and commercial harvesters, and by fisheries researchers. It is not an in depth treatment of fish health. Parasites that are uncommon or too small to be seen with the naked eye and diseases that are poorly known are not discussed. Relatively little research has been conducted on fish parasites in the region, less still on fish diseases and injuries.

The Human Ehrlichioses In The United States, Jennifer H. Mcquiston, Christopher D. Paddock, Robert C. Holman, James E. Childs Jan 1999

The Human Ehrlichioses In The United States, Jennifer H. Mcquiston, Christopher D. Paddock, Robert C. Holman, James E. Childs

Zoonotics and Wildlife Disease: Publications

The emerging tick-borne zoonoses human monocytic ehrlichiosis (HME) and human granulocytic ehrlichiosis (HGE) are underreported in the United States. From 1986 through 1997, 1,223 cases (742 HME, 449 HGE, and 32 not ascribed to a specific ehrlichial agent) were reported by state health departments. HME was most commonly reported from southeastern and southcentral states, while HGE was most often reported from northeastern and upper midwestern states. The annual number of reported cases increased sharply, from 69 in 1994 to 364 in 1997, coincident with an increase in the number of states making these conditions notifiable. From 1986 through 1997, 827 …

Long-Term Studies Of Hantavirus Reservoir Populations In The Southwestern United States: A Synthesis, James N. Mills, Thomas G. Ksiazek, C.J. Peters, James E. Childs Jan 1999

Long-Term Studies Of Hantavirus Reservoir Populations In The Southwestern United States: A Synthesis, James N. Mills, Thomas G. Ksiazek, C.J. Peters, James E. Childs

Zoonotics and Wildlife Disease: Publications

A series of intensive, longitudinal, mark-recapture studies of hantavirus infection dynamics in reservoir populations in the southwestern United States indicates consistent patterns as well as important differences among sites and host-virus associations. All studies found a higher prevalence of infection in older (particularly male) mice; one study associated wounds with seropositivity. These findings are consistent with horizontal transmission and transmission through fighting between adult male rodents. Despite very low rodent densities at some sites, low-level hantavirus infection continued, perhaps because of persistent infection in a few long-lived rodents or periodic reintroduction of virus from neighboring populations. Prevalence of hantavirus antibody …

Diagnosis Of Human Ehrlichiosis By Pcr Assay Of Acute-Phase Serum, James A. Comer, William L. Nicholson, John W. Sumner, James G. Olson, James E. Childs Jan 1999

Diagnosis Of Human Ehrlichiosis By Pcr Assay Of Acute-Phase Serum, James A. Comer, William L. Nicholson, John W. Sumner, James G. Olson, James E. Childs

Zoonotics and Wildlife Disease: Publications

A PCR assay of 43 acute-phase serum samples was evaluated as a method for early detection of human granulocytic ehrlichiosis (HGE) and determination of etiology when serologic testing is inconclusive. Sequenceconfirmed products of the HGE agent were amplified from three individuals residing or having exposure history in Minnesota or Wisconsin, and similarly confirmed products from Ehrlichia chaffeensis were amplified from three individuals from Florida or Maryland. Etiology, as determined by PCR and serology, was the same whenever there was a fourfold difference between the maximum titers of antibodies to both antigens, indicating that presumptive determination of etiology may be based …

Outcome Of Diagnostic Tests Using Samples From Patients With Culture-Proven Human Monocytic Ehrlichiosis: Implications For Surveillance, James E. Childs, John W. Sumner, William L. Nicholson, Robert F. Massung, Steven M. Standaert, Christopher D. Paddock

Zoonotics and Wildlife Disease: Publications

We describe the concordance among results from various laboratory tests using samples derived from nine culture-proven cases of human monocytic ehrlichiosis (HME) caused by Ehrlichia chaffeensis. A class-specific indirect immunofluorescence assay for immunoglobulin M (IgM) and IgG, using E. chaffeensis antigen, identified 44 and 33% of the isolation-confirmed HME patients on the basis of samples obtained at initial clinical presentation, respectively; detection of morulae in blood smears was similarly insensitive (22% positive). PCR amplifications of ehrlichial DNA targeting the 16S rRNA gene, the variable-length PCR target gene, and the groESL operon were positive for whole blood specimens obtained …

Zoonotics and Wildlife Disease: Publications

A 3-month ecologic investigation was done to identify the reservoir of Ebola virus following the 1995 outbreak in Kikwit, Democratic Republic of the Congo. Efforts focused on the fields where the putative primary case had worked but included other habitats near Kikwit. Samples were collected from 3066 vertebrates and tested for the presence of antibodies to Ebola (subtype Zaire) virus: All tests were negative, and attempts to isolate Ebola virus were unsuccessful. The investigation was hampered by a lack of information beyond the daily activities of the primary case, a lack of information on Ebola virus ecology, which precluded the …

Population Dynamics Of A Naturally Occurring Heterogeneous Mixture Of Borrelia Burgdorferi Clones, Erick K. Hofmeister, Gregory E. Glass, James E. Childs, David H. Persing Jan 1999

Population Dynamics Of A Naturally Occurring Heterogeneous Mixture Of Borrelia Burgdorferi Clones, Erick K. Hofmeister, Gregory E. Glass, James E. Childs, David H. Persing

Zoonotics and Wildlife Disease: Publications

Two unique isolates of Borrelia burgdorferi, differing in plasmid content and outer surface protein C expression, were cultured on sequential captures of a single free-living Peromyscus leucopus mouse and were examined for differences in transmissibility. Both isolates were transmissible from inoculated C.B-17 mice to larval Ixodes scapularis ticks and, subsequently, from infected nymphal ticks to C3H/HeJ mice. Plasmid and protein analyses suggested that the original isolates were a mixed population of B. burgdorferi, and cloning by limiting dilution resulted in the identification of two clonal groups. In addition to being heterogeneous in plasmid and genomic macrorestriction analyses, the …

Hofmeister, David H. Persing, Denise A. Robison, Arnold G. Steigerwalt, Don J. Brenner

Zoonotics and Wildlife Disease: Publications

Bacteremia with fever due to a novel subspecies of Bartonella vinsonii was found in a cattle rancher. The subspecies shared major characteristics of the genus Bartonella in terms of most biochemical features and cellular fatty acid profile, but it was distinguishable from other subspecies of B. vinsonii by good growth on heart infusion agar supplemented with X factor and by its pattern of enzymatic hydrolysis of peptide substrates. DNA relatedness studies verified that the isolate belonged to the genus Bartonella and that it was genotypically related to B. vinsonii. The highest level of relatedness was observed with recently characterized …

A Comparison Of Wildlife Control And Cattle Vaccination As Methods For The Control Of Bovine Tuberculosis, R. R. Kao, M. G. Roberts Jan 1999

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 …
