Diseased dogs isoamylases in clinically normal and diseased dogs.

Isoamylases in normal canine sera were separated on cellulose acetate membranes using a discontinuous buffer system without EDTA. Four peaks of amylase activity were present in 17 of 24 sera. Normal values were established. The majority of activity was present in Peak 4 (cathodal isoamylase). Tissue extracts of pancreas, duodenum, kidney, lung, testis, spleen and uterus-ovaries contained Peak 4 isoamylase. Liver and salivary gland lacked all isoamylase activity. Pancreas contained Peak 3 in addition to Peak 4 isoamylase. A tissue origin for Peaks 1 and 2 was not identified. An overall lack of resolution resulted from the inclusion of EDTA in the electrophoresis buffer system. This may account for previous findings suggesting that pancreatic amylase is not present in normal canine serum. An increase in the Peak 3 isoamylase was present in dogs with pancreatitis while dogs with pancreatic atrophy had a decrease in all isoamylases. Total amylase activity was significantly (p < 0.05) decreased in dogs with pancreatic atrophy.

Anticardiolipin antibodies in healthy and diseased dogs.

The concentrations of anticardiolipin immunoglobulin G (IgG) were measured in 134 healthy dogs and 63 diseased dogs by an elisa. The mean (sd) concentration in the healthy dogs was 5.40 (2.60) IgG phospholipid (gpl) units, and concentrations greater than 11 gpl were considered as above the normal range. On this basis, 30 (47.6 per cent) of the diseased dogs were within the normal range, with a mean of 5.45 (3.07) gpl and the other 33 had levels above the normal range (P<0.001); 19 of them had a mean level of 22.2 (5.66) gpl, 10 had a mean level of 49.1 (11.2) gpl, and four had a mean level of 85.8 (9.64) gpl. Levels above the normal range were more frequent in females (59.4 per cent) than in males (45.1 per cent), but were higher in males (45.5 [34.71] v 42.91 [22.0] gpl). In addition, they were more frequent and higher in older dogs (66.7 per cent, 40.4 [24.0] gpl) than in younger dogs (33.3 per cent, 33.5 [21.4] gpl).

Antimicrobial susceptibility of Staphylococcus intermedius isolated from healthy and diseased dogs.

A total of 90 strains of Staphylococcus intermedius isolated from dogs were examined for antimicrobial susceptibility. There were no significant differences in the distribution patterns of MICs between strains from 1982 to 1985 and those from 1999, and between strains from healthy dogs and those from diseased dogs. All of the strains were susceptible to ABPC, DMPPC, CEX, TDM, ERFX, BFLX, and FF at concentrations of 0.05 to 6.25 microg/ml. The MICs of OTC, KM, EM, AIV-TS, and LCM were distributed in a broad range of 0.1 to >100 microg/ml, indicating the existence of resistant as well as susceptible populations of S. intermedius. Thirty-three strains (36.7%) were resistant to one or more anitmicrobial agents such as OTC (n=32), KM (n=9), EM (n=7), AIV-TS (n=7), and LCM (n=7).

First cases of animal diseases published since 2000. 6. First update of dog diseases.

In 2003, Veterinary Quarterly started with the publication of a series of articles reviewing first reports on animal diseases. The articles are arranged in order of animal species. They are regularly updated adding overlooked as well as new first reports. This article is the first update of a review on "first cases" of dog diseases. The following five cases are discussed: Dermatitis in a dog associated with an unidentified Toxoplasma gondii-like parasite. Gastrointestinal cryptosporidiosis in a puppy. Mucinous variant of rete testis adenocarcinoma. Neuronal ceroid-lipofuscinosis in a Labrador Retriever. Salivary gland basal cell adenocarcinoma. After a short introduction, the bibliographical data, the abstract of the author(s) and some additional information derived from the article are given.

Serotypes and antimicrobial susceptibility of Pseudomonas aeruginosa strains isolated from diseased dogs.

Strains of Pseudomonas aeruginosa isolated from diseased dogs in Tokyo area during 1983 through 1986 were serotyped and assayed for antimicrobial susceptibility to obtain an epizootiological aspect of canine P. aeruginosa infection. Major sources of specimens were ear and nasal discharges and urine. The results of O-antigen typing using a monoclonal antibody kit showed that the most predominant serotype was type M. Types G and B were also major serotypes. In a yearly distribution of serotypes, type I was almost limited in 1986, and was isolated mainly from surgical wounds, which showed an episode of nosocomial infection, whereas that of type M or B was dispersed during 4 years from 1983 to 1986. As a result of antimicrobial susceptibility test, most canine strains were considered to be susceptible to 4 drugs, which were commonly used in both human and veterinary clinics, in contrast to human isolates.

The possible enhancement of parvovirus vaccination on the mortality rate of diseased dogs.

A survey was conducted by using questionnaires dealing with morbidity and mortality of young dogs. Seventy-one clinical evaluations of diseased dogs were included in this survey. The cases were divided into 3 groups according to their vaccination history: 1. dogs vaccinated with the parvovirus and distemper live modified vaccine; 2. dogs vaccinated with the killed parvovirus vaccine; 3. non-vaccinated dogs. Statistical analysis of the information obtained by analyzing the questionnaires gave the following results: The survival rate of the non-vaccinated and killed parvovirus vaccine-vaccinated dogs was significantly higher than that of the dogs which were vaccinated by the live modified vaccine. No such difference was encountered between groups 2 and 3. This finding, once more, supports the notion that the live modified parvovirus vaccine may have an immunosuppressive property.

Alpha 1-acid glycoprotein and serum binding of drugs in healthy and diseased dogs.

Inter-individual variation in drug serum protein binding was studied in healthy dogs and in dogs with inflammatory diseases for lidocaine, oxprenolol and propranolol, which bind mainly to alpha 1-acid glycoprotein (alpha 1-AGP), and for diazepam, digitoxin and phenytoin, which bind mainly to albumin. For the drugs mostly bound to alpha 1-AGP, in both groups of dogs binding varied considerably, and it was markedly higher in dogs with inflammatory disease. For the other drugs, the variation in binding was smaller and did not differ between the two groups of dogs. In both groups of dogs, the alpha 1-AGP concentration varied widely; it was higher in the serum of the dogs with inflammation, while the concentration of albumin was lower in these animals. There was a significant negative correlation between percentage free lidocaine, oxprenolol or propranolol and alpha 1-AGP concentration, suggesting that the inter-individual variation in binding of these drugs is due to the variation in alpha 1-AGP concentration. There was a marked intra-individual variation in lidocaine binding and in serum alpha 1-AGP concentration, studied over a period of 3 weeks in healthy dogs; a significant negative correlation between percentage free lidocaine and alpha 1-AGP concentration was obtained.

Occurrence of Malassezia species in healthy and dermatologically diseased dogs.

The presence of Malassezia spp. yeasts was investigated in dermatological specimens of 224 dogs, 164 dermatologically diseased and 60 normal dogs. Subjects included in the study were of different breed, age, sex and habitat. Malassezia spp. positive cultures were obtained in 142 (63.4%) specimens: 67.6% from dermatologically diseased subjects and 51.6% from healthy dogs. Malassezia pachydermatis, either as a pure culture or in association with lipid-dependent species, was identified in 138 (97%) specimens. Malassezia furfur was identified in 69 (48.6%) specimens and was associated with other Malassezia species in 68 dogs, as a pure culture in one subject: at the best of our knowledge, this species was identified before as the sole species from canine dermatitis. Malassezia sympodialis was identified in 11 (7.7%) specimens, always in association with other species: it was never isolated from kennel dogs. Statistical analysis of data showed a very significant difference (P < 0.01) in the prevalence of isolation of Malassezia spp. between animals with and without dermatological signs, and in the distribution of cultural burden between diseased and healthy dogs. A statistically significant difference (P<0.05) was also detected in the group of animals between 1- and 5-years of age. No significant difference was found between male and female dogs.

A case of shaker dog disease in a miniature dachshund.

A male miniature Dachshund, twenty-two months of age, was referred with paroxysmal generalized tremors as a main clinical sign. There were no abnormalities in the neurological examination except the lack of bilateral menace responses, and in the magnetic resonance imaging of its brain. Analysis of cerebro-spinal fluid revealed a slight rise in protein concentration and an increase in the number of cells. This case with brown hair was diagnosed as the shaker dog disease, which has also been well known as "little white shakers" syndrome due to being found in small dogs with white hair, because the clinical signs were exactly analogous to the shaker dog disease, and the generalized tremors disappeared on the first day after the administration of prednisolone and diazepam.

Effect of serum on lymphocyte blastogenesis. I. Basic characteristics of action by diseased dog serum.

The immunoregulatory effect of serum on phytomitogen-induced lymphocyte blastogenesis was studied in 4 sera from diseased dogs and 1 serum from a clinically healthy dog. The results indicated that: (1) Each of the diseased animals responded to the given infection with a specific pattern of blastogenesis inhibition. (2) The blastogenesis suppression in vitro was proportional to the content of the suppressive serum in the medium. (3) A simultaneous presence of the mitogen and the suppressing "serum's lymphocyte immunoregulatory factors" (SLIF) was necessary for inducing blastogenesis suppression. (4) The suppressive sera most probably acted directly on the cells. (5) The final effect of the sera on lymphocyte blastogenesis was a result of an orchestrated action of blastogenesis-supporting, augmenting, and suppressing SLIF cooperating with the mitogen. (6) The suppressive pattern varied with the individual peripheral blood lymphocytes populations used in the test. (7) The blastogenesis-suppressing SLIF was heat-stable, noncytotoxic, and was not or only partially removable by absorption with peripheral blood lymphocytes. (8) The testing of SLIF activities required the use of various animal lymphocytes and a relatively complex setup of mitogens and control serum combinations for correct interpretations.

Serum immunoglobulin A concentrations in normal and diseased dogs.

The normal level of serum IgA in Western Australian dogs was defined by single radial immunodiffusion using sera from 100 healthy randomly selected adult crossbred animals. Serum IgA values of 185 animals from six breeds were also determined. The mean and variance of serum IgA of these groups were similar to the crossbred dogs with the exception of German shepherd dogs where these values were statistically greater. In addition, 210 dogs with a range of chronic diseases (autoimmune, hypersensitivity, pyoderma, neoplasia, demodecosis, disseminated aspergillosis) were assayed and low values recorded in five cases. In all disease groups the mean serum IgA value was significantly greater than in the crossbred group and the variance significantly greater in most of these groups. The German shepherd group were the only normal dogs with a mean and variance similar to those of the clinical series suggesting that this breed may have a primary defect in IgA metabolism.

Total hemolytic complement values in normal and diseased dog populations.

The optimum conditions for handling and storage of canine sera for total hemolytic complement assays were assessed. Sera from 113 normal dogs and 217 clinical admissions to the University of Pennsylvania Veterinary Hospital were assayed for total hemolytic complement levels. Normal sera had a mean value of 185 CH50 units. Sera from animals with systemic lupus erythematosus and hemorrhagic gastroenteritis, had significantly lower mean levels of complement than the normal group. Sera from dogs with generalized demodectic mange, tumors, various inflammatory diseases, hypothyroidism, seborrhea, and rheumatoid arthritis had values significantly higher than the normal population.

Development of an enzyme-linked immunosorbent assay for the detection of IgG subclasses in the serum of normal and diseased dogs.

The present study describes the development of an enzyme-linked immunosorbent assay capable of quantifying serum antibody of all four canine IgG subclasses. A panel of subclass-restricted and subclass-specific monoclonal antibodies was used to measure IgG subclasses in the serum of healthy dogs, as well as in dogs with a range of clinical diseases. The subclasses have been redefined as IgG1, IgG2, IgG3 and IgG4 based on a comparison with the relative concentration and electrophoretic mobilities of human IgG subclasses. In serum samples from healthy dogs, the concentration of IgG1 (mean, 8.17 +/- 0.95 mg ml-1) and IgG2 (mean, 8.15 +/- 3.16 mg ml-1) were very similar and considerably higher than the levels of IgG3 (mean, 0.36 +/- 0.43 mg ml-1) and IgG4 (mean, 0.95 +/- 0.45 mg ml-1). There was no apparent difference in the level of subclasses between the different breeds comprising this normal population. Sera from dogs with a range of immune-mediated or inflammatory diseases all had markedly elevated levels of IgG2 (more than 13 mg ml-1), but IgG1 decreased (less than 4 mg ml-1) to levels below the normal range.
