Bovine mastitis due to Prototheca zopfii leads to reduced milk production and is difficult to cure. Therefore, prevention is the best approach and this is best achieved through the use of effective disinfectants. The aim of this study was to evaluate the in vitro algaecide efficacy of conventional disinfectants against strains of P. zopfii genotype 1 and 2. The minimal algaecide concentration (MAC) of alkyldiaminoethylglycine hydrochloride, chlorhexidine, dioxide chlorine, povidone iodine and sodium hypochlorous acid against 10 isolates and the type strain (SAG2063T) of P. zopfii genotype 1 as well as 10 isolates and the type strain (SAG2021T) of P. zopfii genotype 2 were examined using the micro dilution method. This in vitro study indicated that alkyldiaminoethylglycine hydrochloride, chlorhexidine, povidone iodine and sodium hypochlorous acid, but not dioxide chlorine, are effective against both genotypes of P. zopfii.

Although the susceptibility of dermatophytes to antifungal drugs is well documented in humans, the effectiveness in animals has not been previously investigated. The in vitro susceptibility of 54 clinical isolates from animal dermatophytoses to ketoconazole (KTZ), itaconazole (ITZ) and terbinafine (TFN) was measured using microdilution assay (CLSI M38-A2 test) and by the E-test (KTZ and ITZ). All 3 drugs showed antifungal activity, while KTZ displayed the broadest minimum inhibition concentration (MIC) range (0.125–16 μg/ml) against M. canis and M. gypseum. The MIC of KTZ and ITZ was almost the same for human and animal isolates of T. mentagrophytes and T. rubrum. The MIC of TFN was almost the same for dermatophytes isolated from humans and animals.

The association between breed, gender and age and cardiovascular disorders in the insured dog population in Japan was investigated, using multiple logistic regression analysis and data from 299,555 dogs insured between April 2010 and March 2011. The overall annual prevalence of cardiovascular disorder diagnosis was 2.1%. Using the Miniature Dachshund as the reference breed, Cavalier King Charles Spaniel had the highest odds of cardiovascular disorder with a ratio of 16.2 (95% confidence interval: 14.4–18.2), followed by Maltese, Pomeranian, Chihuahua and Shih Tzu. Male dogs had increased odds of 1.2 (1.1–1.3). The dogs had increased odds of having cardiovascular disorder by 1.5 times as their age increased by one year.

Two cats with abdominal effusion and anorexia were diagnosed as feline infectious peritonitis (FIP). We tried to evaluate the effect of thromboxane (Tx) synthetase inhibitor, ozagrel hydrochloride, on the progression of symptoms and clinicopathologic data characteristic to FIP. After administration of Tx synthetase inhibitor, improvement of appetite and activity, decreases of peritoneal effusion, reduction of leukocyte number to normal level, and improvement of hyper γ-globulinemia were found in 2 cats with FIP. These findings suggest that the vasculitis in FIP can be successfully treated with Tx synthetase inhibitor which inhibits platelet aggregation.

Feline upper respiratory tract infection due to Aspergillus spp. is considered an emerging disease, with the number of reported cases continuing to rise. In this study, we report the first case of feline sinonasal aspergillosis caused by Aspergillus fischeri in Japan. The patient presented after 2 months of progressive facial deformity around the nose and nasal discharge. The isolate from this case was susceptible to itraconazole (ITZ), voriconazole, and micafungin, but was resistant to amphotericine B. However, the infected cat died approximately 1 month after referral, despite treatment for 12 days ITZ administered orally at 10 mg/kg.

Otitis media of the left ear was diagnosed by video otoscopic examination in a 7-year-old, intact male Shih-tzu dog (weight, 5.1 kg), that also had three complex ceruminous adenomas and a Pseudomonas aeruginosa infection in the left ear canal. In such cases, total ear canal ablation is usually required. However, a complete cure was achieved in the present case without total ear canal ablation. The complex ceruminous adenomas were excised using a diode laser, and repeated cleansing of the tympanic cavity and ear canal was implemented using a video otoscope. As a result, the ear canal was closed in a U-form, and the otitis media was cured.

Topical or oral azole antifungals are commonly used in canine atopic dermatitis (AD) as the lipophilic yeast Malassezia pachydermatis exacerbates canine AD. To examine whether canine AD lesions harbor azole-resistant M. pachydermatis isolates in East Asia, we investigated the in vitro susceptibility of M. pachydermatis isolates to ketoconazole (KTZ) and itraconazole (ITZ) obtained from AD lesions of canines in Japan, Korea and Taiwan. The minimum inhibitory concentrations (MICs) of KTZ and ITZ were measured by the E-test using Sabouraud’s dextrose agar with 0.5% Tween 40. The MICs of KTZ and ITZ for isolates from canines with AD were significantly higher from the MICs for isolates from healthy canines. Our findings suggested that the clinical isolates from canine AD skin lesions were less susceptible to azoles than those from normal canine skin in East Asia.

Isolates of the yeast Malassezia pachydermatis obtained from skin samples of healthy dogs and of dogs with atopic dermatitis in Japan, Taiwan and Korea were molecularly characterized using intergenic pacer 1 (IGS1) region analysis. The percentage of IGS1 subtype isolates detected in healthy skin was as follows: 1A (6%), 1B (27%), 1C (11%), 2A (6%), 2B (6%), 3A (11%), 3B (6%), 3C (3%) and 3D (24%). In contrast, the most prevalent isolates detected in skin lesions of atopic dermatitis were subtype 3D in Japan and Taiwan and subtype 3C in Korea. All subtype isolates grew well on acidic medium (pH 6). However, subtype 3C and 3D isolates grew better than the other subtype isolates on medium at pH 8.

Aspergillus udagawae and A. viridinutans are members of the section Fumigati; both cause invasive aspergillosis in humans. These two Aspergillus species are discriminated from A. fumigatus by molecular methods. Herein, we report two cases of feline orbital aspergillosis, one caused by A. udagawae and the other by A. viridinutans. To our knowledge, Case 1 represents the first reported case of treatment of A. udagawae with a high dosage of itraconazole, and Case 2 represents the first reported case of A. viridinutans infection associated with sarcoma. Identification of the etiologic agents of these cases was confirmed by comparative analyses of the sequences of β-tubulin-encoding genes. With the spread of non-fumigatus aspergillosis, increasing emphasis should be placed on molecular identification of the infecting Aspergillus species and the use of in vitro drug susceptibility tests to ensure the selection of appropriate antibiotics.

The small molecule inhibitor, ABT-737, inhibits Bcl-2 that is overexpressed in many tumor cell lines and, in combination with an anticancer drug, can strongly enhance proapoptotic activity. In the present study, we evaluated the inhibitory activity of ABT-737 on the survival of a canine melanoma cell line (MCM-N1). MCM-N1 cell viability was decreased following 24- and 48-hr culture with ABT-737, depending on ABT-737 concentration, while cell viability was unchanged in controls. ABT-737 synergized with carboplatin to promote cell death. Notably, approximately 50% of MCM-N1 cells survived following culture with 2-4 μg/ml of carboplatin; whereas, less than 20% of MCM-N1 cells survived following culture with ABT-737 (1 mM) plus carboplatin (2-10 μg/ml).
