    Notes: Abstract The gene (ddc) encoding a novel enzyme, l-2,4-diaminobutyrate decarboxylase (DABA-DC; EC 4.1.1.-) in Acinetobacter baumannii was sequenced, and an open reading frame of 1,530 nucleotides was detected. The sequence of 20 N-terminal amino acids of purified DABA-DC and of its proteolytic peptide fragments coincided with those deduced from the nucleotide sequence determined. Comparison of the predicted amino acid sequence of the A. baumannii enzyme with those of other pyridoxal 5′-phosphate-dependent decarboxylases revealed significant similarity to the group II amino acid decarboxylases and conservation of the putative pyridoxal 5′-phosphate-binding domain.

    Notes: Abstract A novel siderophore, called acinetobactin, with both catecholate and hydroxamate functional groups was isolated from low-iron cultures of Acinetobacter baumannii ATCC 19606. The structure was elucidated by chemical degradation, fast-atom bombardment mass spectrometry and 1H and 13C NMR spectroscopy. Acinetobactin was composed of ω-N-hydroxyhistamine, threonine and 2,3-dihydroxybenzoic acid, the last two components forming an oxazoline ring. Acinetobactin was structurally related to anguibactin, a plasmid-encoded siderophore of Vibrio anguillarum. The only difference was that acinetobactin possessed an oxazoline ring instead of a thiazoline ring. Four of 12 other clinical A. baumannii strains examined produced acinetobactin, indicative of strain-to-strain variation in the ability to produce acinetobactin. In addition, a relatively small amount of acinetobactin was also detected in A. haemolyticus ATCC 17906.

    Notes: Abstract The hyperosmolarity response of the ocular standing potential was recorded in unilateral rhegmatogenous retinal detachment (8 eyes) and in the fellow ‘healthy’ eye (8 eyes). The hyperosmolarity response was greatly suppressed (M-4 SD: M and SD indicate respectively the mean and the standard deviation in normal subjects) in all affected eyes (p 〈 0.005), and slightly abnormal in 2 fellow eyes. The L/D ratio was normal in 2 affected eyes and in all fellow eyes. The hyperosmolarity response in the affected eyes was still greatly suppressed 14 months after successful surgical treatment.

    Notes: Abstract The hyperosmolarity response of the standing potential was recorded in retinitis pigmentosa (20 eyes), central (pericentral) retinitis pigmentosa (4 eyes), pigmented paravenous retinochoroidal atrophy (2 eyes), fundus albipunctatus (8 eyes), and Stargardt's disease (or fundus flavimaculatus) (14 eyes). The light peak/dark trough ratio (the L/D ratio) and the Diamox response were also determined. The hyperosmolarity response was greatly suppressed (less than M-4SD; M and SD indicate respectively the mean and the standard deviation in normal control subjects) in all examined eyes with retinitis pigmentosa (20 eyes) including retinitis pigmentosa sine pigmento (8 eyes), central (pericentral) retinitis pigmentosa (4 eyes), and pigmented paravenous retinochoroidal atrophy (2 eyes). The L/D ratio was larger than 1.26 (M-2.5 SD) in the half of the eyes with the above-described diseases. The hyperosmolarity response was abnormal (less than M-2 SD) in 4 of 8 eyes with fundus albipunctatus. The L/D ratio was normal in all 8 eyes. The hyperosmolarity response was abnormal (less than M-2 SD) in all 14 eyes with Stargardt's disease or fundus flavimaculatus. The L/D ratio was abnormal in 5 of these 14 eyes. The hyperosmolarity response was more frequently abnormal than the L/D ratio in the chorioretinal dystrophies mentioned above, and hence is useful particularly for early diagnosis of these disorders.

    Notes: Abstract The hyperosmolarity response, a drug-induced response from the retinal pigment epithelium, was recorded in diabetic retinopathy. The hyperosmolarity response was occasionally abnormal at the pre-retinopathic stage and at the first stage of retinopathy by Scott classification. The response was frequently abnormal at the second and third stages of retinopathy. The hyperosmolarity response is useful for early diagnosis of pigment epitheliopathy in diabetes.

    Canine C-reactive protein (CRP) does not share common antigenicity with human CRP (1993)

    Notes: Abstract Differences in antigenicity between human and canine C-reactive proteins were investigated by Western blotting analysis. It was confirmed that several commercial anti-human CRP sera reacted with canine CRP. However, 34 anti-canine CRP sera prepared by immunization of rabbits and goats with canine CRP all reacted with canine CRP but not with human CRP in either immunoelectrophoresis or Western blotting. Immunization with human CRP produced a cross-reacting antibody that reacted with canine CRP. Conversely, immunization with canine CRP did not produce a cross-reacting antibody that reacted with human CRP. These findings may be interpreted as showing that, while canine and human CRPs do not share common antigenicity, they do contain structurally similar antigenic determinants.

    Quantitative capillary reversed passive latex agglutination test for C-reactive protein (CRP) in the dog (1996)

    Notes: Abstract A capillary reversed passive latex agglutination test (capillary RPLA) was developed which allows quantification of serum C-reactive protein (CRP) within approximately 15 min. The logarithmic regression line (calibration curve) obtained after measuring each CRP concentration three times in twofold dilutions of a standard canine serum containing 222 μg/ml of CRP was y=6.394+0.030x (r=0.995). Capillary RPLA permitted quantification of CRP in the range 6.9–222 μg/ml. The coefficients of variation ranged from 10.28% to 12.40%. The recovery rates (percentage recovery) of CRP by capillary RPLA were within the range 87% to 106%. On measuring the CRP concentrations in sera from 78 dogs by capillary RPLA, single radial immunodiffusion (SRID) and enzyme-linked immunosorbent assay (ELISA), close correlations were demonstrated between SRID and capillary RPLA (y=7.250+1.109x, r=0.978), between SRID and ELISA (y=3.042+1.059x, r=0.967), and between capillary RPLA and ELISA (y=1.778+0.929x, r=0.962). Capillary RPLA may be considered useful as a routine biochemical technique for measurement of serum CRP concentration in the dog.

    Notes: Abstract A reversed passive latex agglutination test (RPLA) using anti-canine haemoglobin (Hb) antibody was developed for detecting bleeding in the lower digestive organs in dogs, and its applicability as a simple test for faecal occult blood was assessed. In Ouchterlony's gel immunodiffusion test, the anti-canine Hb antibody used to sensitize the latex reacted with canine Hb but not with Hbs, plasmas or meat extracts from pigs, goats, sheep, cattle, horses or chickens, or with fish extracts. Using latex sensitized with 50 µg/mg of anti-canine Hb IgG antibody, the lowest limit of detection for canine Hb was 21 µg/ml, and the latex reacted negatively with all test specimens other than canine Hb. In an in vitro experiment with a mixture of canine faeces and erythrocytes, the antigenicity of the Hb was found to undergo only very slight changes even when the specimens were allowed to stand for 12 h at room temperature. Hb could not be detected by RPLA in any of four successive faecal samples from three experimental dogs after infusion of autologous blood (5, 3 or 1 ml) into the stomach. In 3 other experimental dogs given an infusion of autologous blood (5, 3 or 1 ml) into the ascending colon, the presence of Hb was confirmed by RPLA in all four successive faecal samples obtained from those which received 5 or 3 ml of blood and in all except that obtained following the first defecation from the animal which had received 1 ml of blood.

    Notes: Abstract This study was undertaken to investigate whether the level of C-reactive protein (CRP) in the serum of dogs undergoes physiological variation, using 10 normal Beagle dogs (5 males and 5 females), 1–2 years old, maintained in a healthy condition in a controlled environment. The CRP concentration in the sera collected seven times each day at intervals of approximately 3 h ranged from 0.8 to 16.4 µg/ml (mean 5.06±3.60) in one experiment and from 0.8 to 14.0 µg/ml (mean 4.50±2.80) in a second experiment. On examining the 24-h variations in the concentration of CRP in serum, neither consistent changes nor a definite pattern of circadian rhythm was detected. During 28 days observation, only very slight changes, which seemed attributable to analytical errors, were seen in any of the dogs, except one. The concentration of CRP in the serum during the 28 days ranged from 0.8 to 22.6 µg/ml (mean 3.65±1.40). The concentrations underwent no significant variations in individual dogs, but significant differences were found between the dogs (p〈0.01).
