25. Genetics of Hemoglobin in the Deer Mouse, PEROMYSCUS MANICULATUS . I. Multiple α- and β-Globin Structural Loci
Genetic data, together with molecular structure studies, have demonstrated that the complex hemoglobin phenotypes in four subspecies of P. maniculatus are generated by at least four, and probably five, globin structural loci. The Hba and Hbc loci apparently arose by duplication of an ancestral α-type locus, while Hbb, Hbd, and Hbe apparently were derived

26. Dusky-Footed Wood Rats (Neotoma fuscipes) as Reservoirs of Granulocytic Ehrlichiae (Rickettsiales: Ehrlichieae) in Northern California
Dusky-footed wood rats (Neotoma fuscipes) and Peromyscus sp. mice (P. maniculatus and P. truei) were collected from one site in Placer County, one site in Santa Cruz County, and two sites in Sonoma County in northern California. Serum or plasma samples from 260 rodents were tested for antibodies to the agent of human granulocytic ehrlichiosis. Of these, samp

27. Generation of a Recombinant Cytomegalovirus for Expression of a Hantavirus Glycoprotein
A cytomegalovirus (CMV) was isolated from its natural host, Peromyscus maniculatus, and was designated Peromyscus CMV (PCMV). A recombinant PCMV was constructed that contained Sin Nombre virus glycoprotein G1 (SNV-G1) fused in frame to the enhanced green fluorescent protein (EGFP) gene inserted into a site homologous to the human CMV UL33 (P33) gene. The rec

28. Seasonal prevalence of Borrelia burgdorferi in natural populations of white-footed mice, Peromyscus leucopus.
Borrelia burgdorferi, the etiologic agent of Lyme disease, was isolated from 111 of 237 Peromyscus leucopus captured during all seasons of the year. Borreliae were cultured from tissues of the spleen (101 mice), left kidney (76 mice), and right kidney (73 mice), from blood (12 mice), and from one fetus. Mice were infected during the winter, when immature Ixo

29. Serologic analyses of Peromyscus leucopus, a rodent reservoir for Borrelia burgdorferi, in northeastern United States.
An enzyme-linked immunosorbent assay (ELISA) and indirect fluorescent-antibody test were used to detect antibodies to Borrelia burgdorferi, the causative agent of Lyme disease, in Peromyscus leucopus (white-footed mouse). Of the 661 mice captured in Connecticut, Rhode Island, and New York during 1980 and 1983 to 1987, 166 (25.1%) had antibodies to B. burgdor

30. Detection of Borrelia burgdorferi in urine of Peromyscus leucopus by inhibition enzyme-linked immunosorbent assay.
An inhibition enzyme-linked immunosorbent assay was developed to detect Borrelia burgdorferi, the etiologic agent of Lyme borreliosis, in urine from white-footed mice (Peromyscus leucopus). Of the 87 urine specimens tested from 87 mice collected in widely separated tick-infested sites in Connecticut, 57 (65.5%) contained detectable concentrations of spiroche

31. Bartonella Strains from Ground Squirrels Are Identical to Bartonella washoensis Isolated from a Human Patient
The most likely animal source of a human case of cardiac disease in Washoe County, Nev., was identified by comparison of DNA sequences of three genes (citrate synthase gltA, 60-kDa heat shock protein gene groEL, and 16S rRNA gene) of Bartonella washoensis cultured from the human patient in question and of Bartonella isolates obtained from the following Nevad

32. Distribution of Borrelia burgdorferi in host mice in Pennsylvania.
Host mice (Peromyscus leucopus and Peromyscus maniculatus) were sampled throughout the state of Pennsylvania to determine the geographical and ecological distribution of the Lyme disease spirochete Borrelia burgdorferi. All 67 counties of the state were sampled. A total of 1,619 mice were captured from a total of 157 sites during the period 1990 to 1993 for

33. Survey for Ixodes spp. and Borrelia burgdorferi in southeastern Wisconsin and northeastern Illinois.
Forested areas adjacent to Milwaukee, Wis., and Chicago, Ill., were investigated for rodents and ticks infected with Borrelia burgdorferi, the causative agent of Lyme disease. White-footed mice (Peromyscus leucopus or Peromyscus maniculatus), meadow voles (Microtus pennsylvanicus), and eastern chipmunks (Tamias striatus) were captured; and specimens from the

34. Genetics of Hemoglobin in the Deer Mouse, PEROMYSCUS MANICULATUS . II. Multiple Alleles at Regulatory Loci
Deer mice are polymorphic for electrophoretic hemoglobin phenotypes showing one, two, or three bands. Within the multibanded phenotypes, there is considerable variation in the hemoglobin partitioning, defined as the fraction of total hemoglobin made up by the secondary and tertiary bands. In subspecies sonoriensis, for example, hemoglobin partitionings rang

35. Modoc Viral Infections in the Deer Mouse Peromyscus maniculatus
The pathogenesis of Modoc virus and its mechanism of transmission were investigated in Peromyscus maniculatus gambeli (deer mouse) as a model to understand the natural history of this virus. Animals were readily infected by the intranasal or subcutaneous route of inoculation. Virus could be detected by direct isolation techniques in many organs and body flui

36. Antibody response in white-footed mice (Peromyscus leucopus) experimentally infected with the Lyme disease spirochete (Borrelia burgdorferi).
White-footed mice (Peromyscus leucopus), the primary reservoir for Borrelia burgdorferi in the northern midwest and northeastern United States, were experimentally inoculated with an infectious strain or a noninfectious strain of the Lyme disease spirochete and examined for their specific antibody response with the enzyme-linked immunosorbent assay and Weste
