Borrelia burgdorferi infection was diagnosed serologically in a dog with lethargy, stiffness, and anorexia. Treatment with ampicillin and chloramphenicol did not alleviate the signs. Azotemia, proteinuria, cylindruria, pyuria, and hematuria developed over a 3-month period. Antibody titer for B burgdorferi remained high (1:8,192) during this time. Renal histopathologic findings included severe, chronic, diffuse, membranoproliferative glomerulonephritis and moderate chronic, multifocal, interstitial nephritis. Borrelia burgdorferi organisms were identified in renal tissue and in urine by results of immunofluorescent studies and bacteriologic culture, respectively.

During 1980 and 1981, we compared antibiotic regimens in 108 adult patients with early Lyme disease. Erythema chronicum migrans and its associated symptoms resolved faster in penicillin- or tetracycline-treated patients than in those given erythromycin (mean duration, 5.4 and 5.7 versus 9.2 days, F = 3.38, p less than 0.05). None of 39 patients given tetracycline developed major late complications (meningoencephalitis, myocarditis, or recurrent attacks of arthritis) compared with 3 of 40 penicillin-treated patients and 4 of 29 given erythromycin (chi square with 2 degrees of freedom = 5.33, p = 0.07). In 1982, all 49 adult patients were given tetracycline; again, none of them developed major complications. However, with all three antibiotic agents nearly half of the patients had minor late symptoms such as headache, musculoskeletal pain, and lethargy. These complications correlated significantly with the initial severity of illness. For patients with early Lyme disease, tetracycline appears to be the most effective drug, then penicillin, and finally erythromycin.

A vaccine consisting of purified Escherichia coli-expressed recombinant full-length outer surface proteins A (OspA) and B (OspB) and the saponin adjuvant QS21 was evaluated for protection against Borrelia burgdorferi infection. Eleven beagles were vaccinated twice and then challenged with 10 field-collected adult female Ixodes scapularis. Xenodiagnosis revealed that all 11 nonvaccinated control dogs and 2 of 10 vaccinated dogs were infected with B. burgdorferi. Six of 11 control dogs also developed fever (0.75 +/- 0.38 degrees C) and were lethargic. One of the control dogs also developed a limp. Both of the infected vaccinated dogs were asymptomatic. Thus, the vaccine prevented tick-vectored infection and associated symptoms of Lyme disease.

A study of literature concerning Lyme borreliosis related to animals was done. In the research work the epidemiology, pathogenesis, diagnosis and treatment of horses, cattle and dogs affected with Lyme borreliosis have been discussed. The clinical signs of Lyme borreliosis in horses are: chronic weight loss, sporadic lameness, laminitis, low grade fever, swollen joints, muscle tenderness and anterior uvetitis. In addition to these clinical sings, neurological sings such as depression, behavioral changes, dysphagia and encephalitis can be seen in chronic cases. Cattle affected with acute Lyme borreliosis often show fever, stiffness, swollen joints and decreased milk production. Chronic weight loss, laminitis and abortion are also a possible outcome of borreliosis in cattle. An early infection of Lyme borreliosis in dogs may give evidence of inapetenca, lethargy, lyphadenopathy, and an acute onset of stiffness or pain while a recurrent intermittent nonerosive arthritis is a more advanced manifestation of canine Lyme borreliosis. Glomerulonephritis and tubular damage secondary to Borrelia burgdorferi infection have been reported to occur in normally infected dogs. In an endemic area atrioventricular heart block has also been reported. The underlying pathogenesis of Lyme disease is still unknown. The diagnosis of clinical Lyme borreliosis is difficult and it depends on a successful recognition of clinical signs, a history of possible exposures to the infection and on serologic testings. The therapy of Lyme borreliosis in animals is based upon the principal therapy of this disease in human medicine.

We demonstrate that Borrelia burgdorferi infection in the rhesus monkey mimics the early and early disseminated phases of human Lyme disease. Clinical, bacteriological, immunological, and pathological signs of infection were investigated during 13 weeks after inoculation of the spirochete. Three animals were given B. burgdorferi (strain JD1) by needle inoculations, six animals were exposed to the bite of B. burgdorferi-infected Ixodes dammini ticks, and three animals were uninfected controls. B. burgdorferi could be recovered from all animals that were given the spirochete. Bacteria were detectable until week 6 postinoculation (p.i.) in blood, until week 8 p.i. in skin biopsies, and at 10 weeks p.i. in the conjunctiva of one of two animals which developed conjunctivitis. Erythema migrans (EM) appeared in one of the three animals infected by needle inoculation and in five of the six animals infected by ticks. Deep dermal perivascular lymphocytic infiltrations (characteristic of human EM) were observed in all animals showing EM clinically. Both EM and conjunctivitis were documented concomitantly with the presence of the spirochete. Lethargy, splenomegaly, and cerebrospinal fluid pleocytosis were also noted in some animals, but the direct connection of these signs with the infection was not shown. The appearance rate of immunoglobulin M and immunoglobulin G antibodies to B. burgdorferi, as well as the antigen spectra recognized, were remarkably similar to those seen in humans. Serum antibodies from infected animals were able to kill B. burgdorferi in vitro in the presence of rhesus complement. The rhesus monkey model appears to be useful for the investigation of the immunology and pathogenesis of Lyme disease and for the development of immunoprophylactic, diagnostic, and chemotherapeutic protocols.

Canine Lyme disease is caused by the spirochete Borrelia burgdorferi after transmission by an Ixodes tick, typically resulting in joint pain, fever and lethargy. Lyme nephritis is a poorly characterized syndrome associated with severe glomerular and tubular renal injury and poor clinical outcome in young to middle-aged dogs positive for exposure to B. burgdorferi. The aims of this study were to identify associations between natural exposure to B. burgdorferi and the presence of microalbuminuria in nonclinical young Labrador and Golden Retrievers and to compare two commonly used serologic tests available to document B. burgdorferi exposure: the Western blot and the commercial point-of-care C6 peptide enzyme-linked immunosorbent assay (ELISA) tests. Microalbuminuria was assessed using a commercial point-of-care ELISA specific for canine albumin. Blood and urine samples from 268 asymptomatic Labrador and Golden Retrievers were included. Of these, 18.7% were positive for B. burgdorferi exposure according to the C6 ELISA; 21.2% were positive for natural exposure to B. burgdorferi and 11.5% for vaccinal antibodies according to the Western blot. The agreement rate was 93% between the two tests (kappa = 0.78, P < 0.0001) for natural exposure. Urine from 6.1% of the dogs was positive for microalbuminuria. There was no association between microalbuminuria and exposure to B. burgdorferi based on results of a Western blot (P = 0.57) or C6 ELISA (P = 0.53). Microalbuminuria is likely not a consequence of B. burgdorferi exposure in young nonclinical Labrador and Golden Retrievers.

A two-year-old male Pointer had been presented with anorexia, cachexia, and weight loss of 10-day duration. Upon physical examination, fever, lethargy, superficial lymph node enlargement, and tick infestation were noted. The only abnormality in CBC and serum chemistry analyses was mild hyperglobulinemia. Spleen was enlarged by radiography, and the lymph nodes showed neutrophilic lymphadenitis by cytological examination. A polymerase chain reaction test for babesiosis and commercial ELISA tests for Ehrlichia canis, heartworm, and Lyme disease was negative except for Lyme disease, which was verified by both an IFA-IgG test and a quantitative C(6) assay. Doxycycline was administered for 2 weeks and the recovery was uneventful. Post-treatment C(6) titer decreased to within normal limits.

In endemic regions, Lyme disease is a potential health threat to dogs. Canine Lyme disease manifests with arthritis-induced lameness, anorexia, fever, lethargy, lymphadenopathy and, in some cases, fatal glomerulonephritis. A recent study revealed that the regional mean for the percentage of seropositive dogs in the north-east of the USA is 11.6%. The outer surface protein C (OspC) of Lyme disease spirochetes is an important virulence factor required for the establishment of infection in mammals. It is a leading candidate in human and canine Lyme disease vaccine development efforts. Over 30 distinct ospC phyletic types have been defined. It has been hypothesized that ospC genotype may influence mammalian host range. In this study, Ixodes scapularis ticks collected from the field in Rhode Island were assessed for infection with B. burgdorferi. Ticks were fed on purpose bred beagles to repletion and infection of the dogs was assessed through serology and PCR. Tissue biopsies (n=2) were collected from each dog 49 days post-tick infestation (dpi) and the ospC genotype of the infecting strains determined by direct PCR of DNA extracted from tissue or by PCR after cultivation of spirochetes from biopsy samples. The dominant ospC types associated with B. burgdorferi canine infections differed from those associated with human infection, indicating a relationship between ospC sequence and preferred host range. Knowledge of the most common ospC genotypes associated specifically with infection of dogs will facilitate the rational design of OspC-based canine Lyme disease vaccines and diagnostic assays.

An 18-yr-old female captive-born chimpanzee (Pan troglodytes) presented with an intermittent history of inappetence, lethargy, and lower limb stiffness. No notable abnormalities were found on exam or complete blood cell count and serum biochemistry analysis. Serologic testing was strongly positive via indirect fluorescent antibody testing and Western blot for Borrelia burgdorferi. Treatment with doxycycline was initiated, and a clinical response was seen within 1 wk. Convalescent serum exhibited an eightfold increase in titer. Serologic testing was performed on several conspecifics with banked serum; while some low positive titers were present and presumed indicative of past exposure, no titer was elevated to the extent of the affected chimpanzee during its course of disease. To the authors' knowledge, this is the first report of suspected Lyme borreliosis in a great ape species, and the case originates from an area of the United States with a high incidence of human borreliosis.
