The pharmacological effects of the anesthetic alfaxalone were evaluated after
intramuscular (IM) administration to 6 healthy beagle dogs. The dogs received three IM
doses each of alfaxalone at increasing dose rates of 5 mg/kg (IM5), 7.5 mg/kg (IM7.5) and
10 mg/kg (IM10) every other day. Anesthetic effect was subjectively
evaluated by using an ordinal scoring system to determine the degree of neuro-depression
and the quality of anesthetic induction and recovery from anesthesia. Cardiorespiratory
variables were measured using noninvasive methods. Alfaxalone administered IM produced
dose-dependent neuro-depression and lateral recumbency (i.e., 36 ± 28 min, 87 ± 26 min and
115 ± 29 min after the IM5, IM7.5 and IM10 treatments, respectively). The endotracheal
tube was tolerated in all dogs for 46 ± 20 and 58 ± 21 min after the IM7.5 and IM10
treatments, respectively. It was not possible to place endotracheal tubes in 5 of the
6 dogs after the IM5 treatment. Most cardiorespiratory variables remained
within clinically acceptable ranges, but hypoxemia was observed by pulse oximetry for 5 to
10 min in 2 dogs receiving the IM10 treatment. Dose-dependent decreases in rectal
temperature, respiratory rate and arterial blood pressure also occurred. The quality of
recovery was considered satisfactory in all dogs receiving each treatment; all the dog
exhibited transient muscular tremors and staggering gait. In conclusion, IM alfaxalone
produced a dose-dependent anesthetic effect with relatively mild cardiorespiratory
depression in dogs. However, hypoxemia may occur at higher IM doses of alfaxalone. 相似文献

To determine the reference level of central venous oxygen saturation (ScvO2)
and clinical efficacy of central venous blood gas analysis, partial pressures of oxygen
and carbon dioxide, pH, oxygen saturation, base excess (B.E.) and HCO3
concentration were compared between simultaneously obtained central venous and arterial
blood samples from conscious healthy 6 dogs and 5 cats. Comparisons between arteriovenous
samples were performed by a paired t-test and Bland-Altman analysis.
Between arteriovenous samples, B.E. showed good agreement, but there were significant
differences in other parameters in the dogs, and no good agreement was detected in cats.
The ScvO2 in dogs and cats were 82.3 ± 3.5 and 62.4 ± 13.5%, respectively.
Central venous blood gas analysis is indispensable, especially in cats. 相似文献

In Japan, Lactococcus garvieae infection has been the main fish disease in aquaculture. Although commercial oral and injectable vaccines have been used
to prevent L. garvieae infection in Japan, L. garvieae has been isolated not only from unvaccinated fish but also from vaccinated fish in which immunity induced by vaccination
had diminished. In order to obtain epidemiological information on this fish pathogen, we conducted biased sinusoidal field
gel electrophoresis (BSFGE) pattern analysis and phage typing of L. garvieae isolates (n = 427) from fish in Japan. These isolates were obtained from 13 different fish species between 1980 and 2007. In the BSFGE
analysis, L. garvieae isolates were classified into 17 groups (S1–S17) based on the SmaI digestion patterns and into four groups (A1–A4) based on the ApaI digestion patterns. Phage typing revealed five different phage susceptibility profiles (A–E) in L. garvieae isolates. Since 2005, comparisons of the results of phage typing and BSFGE have indicated the presence of a novel genotype
(S16/A4) with phage type E. All the strains belonging to this type showed lincomycin sensitivity. 相似文献

The definitive hosts of Metagonimus hakubaensis are reported to be hamsters, rats, mice, dogs, cats, chickens, and quails in experimental infection and Japanese water shrews in natural infection. Here we report that raccoon dogs are new natural definitive hosts of M. hakubaensis, based on morphological and molecular analyses of Metagonimus flukes collected from the host species from Aomori Prefecture, Japan. Moreover, M. hakubaensis recovered from raccoon dogs showed higher fecundity than those recovered from Japanese water shrews. Therefore, raccoon dogs were considered as a more suitable natural definitive host of M. hakubaensis than Japanese water shrews. 相似文献

Population size of soil ammonia-oxidizing bacteria (AOB) was quantified by real-time PCR in a long-term (16 years) field experiment under different fertilizer managements. AOB population sizes in mineral nitrogen-fertilized soils and organic manure-fertilized soil were 10.3 and 3.1 times, respectively, that of the control, while phosphorus and potassium fertilization had no significant effect. On the other hand, the AOB specific nitrification potential (soil nitrification potential per AOB cell) was significantly higher (P < 0.05) in organic manure-fertilized soil than in mineral-fertilized soils and the control, indicating that AOB was likely more metabolically active in organic manure-fertilized soils than in mineral nitrogen-fertilized soils after long-term application. 相似文献

Saddleback-like syndrome is one of the most frequently observed malformations in hatchery-reared red spotted grouper Epinephelus akaara. Saddleback-like syndrome is characterized by a V-shaped dorsal-profile depression behind the head region accompanied by deformities or misalignments of the first to fourth neural spines on the vertebral column and the first to fourth pterygiophores of the dorsal fin. Abnormal swim bladder inflation in several finfish species leads to malformations, particularly of the vertebral column. The present study examined the influence of swim bladder inflation on saddleback-like syndrome in hatchery-reared red spotted grouper. The incidence of saddleback-like syndrome increased as swim bladder inflation rate increased. Additionally, the incidence of saddleback-like syndrome among juveniles with inflated swim bladders was significantly higher than that among juveniles with uninflated swim bladders. The larval swim bladder is located just below the first to fifth vertebrae and the first to fifth dorsal spines, where saddleback-like syndrome occurs. Our results suggest that an inflated swim bladder increases the risk of saddleback-like syndrome in hatchery-reared red spotted grouper. 相似文献
