    On a stock farm in the northeastern district of China, histopathological and electron-microscopic examinations were made of 40 shika deer (Cervus nipponTemminck) aged from 1 day to 2 years and suffering cardiac arrest. Principal pathological changes were myocytolysis and contraction-band necrosis of the myocardial fibers. Ultrastructural examination revealed mitochondrial deformation and calcium deposition. These phenomena resemble those observed in cases of cardiomyopathy caused in other animals by selenium-vitamin E deficiency.

  • Fungal and Bacterial Isolation from Inflamed Guttural Pouches; Drug Susceptibility of the Isolates

    An endoscope was used to perform isolations for fungi and bacteria from the guttural pouches of 14 thoroughbred horses. Drug susceptibilities of the isolates were investigated.Emericella nidulansandAspergillus fumigatuswere isolated from 4 horses. Only the former was isolated from 3 horseseuthanized because of terminal prognosis.E. nidulanswas confirmed as the major causative agent ofguttural-pouch mycosis. Since 19 strains of bacteria were isolated from 13 horses, some of which demonstrated mycosis, itwas suggested that bacterial infection is common in cases of mycotic inflammation of the guttural pouch.Drug-susceptibility tests showed miconazole to be the most active antifungal agent (MIC =3.1μg/ml) againstE.nidulans, whereas amikacin and miocycline in combination were most effective against 30 bacterial isolates (100% sensitivity with this combination.) These 3 drugs, therefore, are thought to be useful in antibiotictreatment of equine guttural-pouch infection.

    Oral administration of ivermectin to 6 dogs with generalized demodicosis resulted in clinicalimprovements in all cases. Four of the dogs received 0.6 mg/kg every 24 hours. Mild ivermectin toxicosis wasobserved in one of these dogs, to which 2.5 mg/kg were administered inadvertently. This side effect disappearedimmediately after treatment stopped. For the other animals in this group, treatment lasted 7 weeks in one case, 12 weeks in one case, and 3 months in one case. The fifth dog received 0.4 mg/kg daily for 8 months. In this case, relapse occurred 3 months after treatment stopped; and the same therapy was repeated for an additional 2 months. Treatment of the sixth dog, to which 0.6 mg/kg was administered every other day, lasted 12 months. Daily oral administration of 0.6 mg/kg proved to be the most effective treatment for dogs with generalized demodicosis.

    A male mongrel cat (age 8 years and 5 months) was referred to our clinic because of syncopal episodes. Electrocardiography revealed paroxysmal third-degree atrioventricular block. Because syncopal episodes became increasingly frequent over a period of 5 months, permanent pacemaker implantion was performed. One year after the operation, no further syncopes had occurred. To the best of our knowledge, this is the first report in Japan of long-term observation of pacemaker implantation in a cat.

    Examination of a male, mixed-breed dog (12 years old) with severe anemia, bleeding tendency, increased serum indirect bilirubin concentration, acanthocytosis of the peripheral blood, and severe hemoglobinuria revealed thrombocytopenia, prolonged bleeding time, prothrombin time, and activated partial thromboplastin time, decreased plasma fibrinogen concentration, and activities of blood-coagulation factors II, V, VII, VIII, IX, X, XI, and XII. In addition, soluble fibrin monomer complex and serum fibrin/fibrinogen degradation products were detected. Postmortem histopathologic examination revealed hemangiosarcoma of the liver and spleen and fibrin thrombi in the veins of gastrointestinal mucosa and the glomeruli of the kidney. On the basis of these findings, the case was diagnosed as disseminated intravascular coagulation with microangiopathic hemolytic anemia complicated by hemangiosarcoma.

    A Parasitological survey was conducted of minke whales (Balaenoptera acutorostrata) from the Western North Pacific Ocean in June-August 1995 and July-September 1996. A total of minkewhales were captured n waters from 35-52° N and 140-170° E. The ecto- and endo parasites found were as follows (prevalence): the copepodPennella balaenoptera (68.4%); the amphipod (whale louse) Cyamus balaenoptera (5.1%); the trematode Lecithodesmus goliath (59.9%); the cestodesDiphyllobothrium macroovatum (13.0%);Diplogonoporus balaenoptera (13.0%);Tetrabothriussp.(4.5%); the nematodeAnisakis simplex (89.8%); and the acanthocephalanBolbosoma nipponicum (100%). Two species of epizoits, Xenobalanus globicipitis (1.1%) andConchoderma virgatum, were also collected.
