Utilizaram-se 22 amostras de material, obtidas de 19 cães com úlcera de córnea, sendo 16 unilaterais e três bilaterais, para isolamento e avaliação da susceptibilidade antimicrobiana das bactérias isoladas. Observou-se crescimento bacteriano em 100% das amostras (n=22). A espécie predominante foi Staphylococcus intermedius (35,5%) seguido de Corynebacterium xerosis (19,3%). Gentamicina, ciprofloxacina, cloranfenicol e tobramicina apresentaram alta eficácia contra todas as bactérias isoladas. Os resultados evidenciam que 80,7% dos isolados foram cocos e bacilos Gram positivos e que estes microrganismos foram sensíveis à gentamicina, ciprofloxacina, cloranfenicol e tobramicina.

A total of 22 clinical specimens were obtained from 19 dogs with corneal ulcer (16 unilateral and three bilateral) for isolation and antimicrobial susceptibility evaluation of the isolated bacteria. Bacterial growth was observed in 100% of the samples (n=22). Staphylococcus intermedius was the predominant species (35.5%), followed by Corynebacterium xerosis (19.3%). Gentamicin, ciprofloxacin, chloramphenicol and tobramycin had a high efficacy against all of the isolated bacteria. The results evidenced that 80.7% of the isolates were Gram positive cocci and Gram positive bacilli, and that those microorganisms were sensitive to gentamicin, ciprofloxacin, chloramphenicol and tobramycin.

The hematological and serum proteins electrophoretic profiles of 13 dogs with distemper (Lentz inclusion body in leukocytes) were studied. The most frequent hematological findings were: normocitic normocromic anemia (61%), leukopenia (46%), left shount (54%), trombocytopenia (69%) and lymphopenia (85%). Electrophoretic analysis of serum proteins showed hypoproteinemia (54%), with reduced albumin and increased alfa-2 globulin. These findings can be used to support the clinical diagnosis of canine distemper.

Os objetivos desta pesquisa foram investigar o possível envolvimento de fungos sapróbios nas dermatomicoses e determinar a incidência de dermatófitos em cães e gatos. Durante um ano, 74 cães e 18 gatos com lesões cutâneas sugestivas de micoses foram incluídos neste estudo. As análises micológicas foram realizadas por microscopia direta e cultivo do fungo em ágar Sabouraud, ágar Sabouraud com cloranfenicol e ágar mycosel. A partir dos 92 espécimes clínicos, 21 resultaram em culturas positivas para dermatófitos, observando-se crescimento exclusivo desses fungos somente em 13. Em oito espécimes, observou-se crescimento simultâneo de dermatófitos e fungos sapróbios. Dentre os 71 espécimes restantes, 10 não apresentaram crescimento fúngico, e pelo menos um fungo sapróbio foi observado em 61 deles. Foram isolados um, dois e três gêneros de fungos sapróbios em 29, 30 e 2 espécimes, respectivamente. Microsporum canis foi encontrado em 6 (28,6%) e 10 espécimes (47,6%) e Trichophyton mentagrophytes em 2 (9,5%) e 3 espécimes (14,3%) de gatos e cães, respectivamente. Os seguintes gêneros de fungos sapróbios foram isolados: Alternaria sp (1,9%), Chaetomium sp (1,9%), Rhizopus sp (2,9%), Curvularia sp (3,9%), Candida sp (6,8%), Trichoderma sp (6,8%), Fusarium sp (7,8%), Cladosporium sp (8,7%), Penicillium sp (21,4%) e Aspergillus sp (37,9%).

The possible involvement of saprobe fungi in dermatomycoses, as well as the determination of the incidence of dermatophytes in dogs and cats were studied. During a period of one year, 74 dogs and 18 cats, with cutaneous lesions suggesting mycoses were included in this study. The mycological analyses were conducted by direct microscopy and by fungal culture on Sabouraud agar, chloramphenicol Sabouraud agar and mycosel agar. Of the 92 samples, 21 resulted in positive cultures for dermatophytes. Dermatophyte fungi pure cultures were obtained from 13 samples. A simultaneous growth of dermatophytes plus saprobe fungi was observed in 8 of the samples. Of the remaining 71 samples, no fungal growth was observed in 10 samples, and at minimum the growth of one saprobe fungi in 61. One, two and three genera of saprobe fungi were isolated in 29, 30 and 2 samples, respectively. Microsporum canis was isolated in 6 (28.6 %) and 10 samples (47.6 %) from cats and dogs, respectively, and Trichophyton mentagrophytes in 2 (9.5 %) and 3 samples (14.3 %) from cats and dogs, respectively. The following genera of saprobe fungi were also isolated: Alternaria sp (1.9%), Chaetomium sp (1.9%), Rhizopus sp (2.9%), Curvularia sp (3.9%), Candida sp (6.8%), Trichoderma sp (6.8%), Fusarium sp (7.8%), Cladosporium sp (8.7%), Penicillium sp (21.4%) and Aspergillus sp (37.9%).
