RESUMO Um Bulldog Inglês de 2 anos apresentou história clínica de doença recorrente do trato urinário inferior, refratária ao tratamento. O hemograma revelou uma discreta linfopenia, hiperproteinemia e hiperglobulinemia. Já a urinálise apontou leucocitúria e bacteriúria. Na ultrassonografia, a bexiga apresentava espessamento focal da parede da bexiga em porção cranial, ecogênica e margens internas irregulares. A biópsia cirúrgica da bexiga foi compatível com cistite folicular. Os sinais clínicos desapareceram após o tratamento com uma combinação de amoxicilina - ácido clavulânico, AINEs, suplementação alimentar de extrato de cranberry associado a unha de gato (fitoterápico da planta Uncaria tomentosa). O acompanhamento, 12 meses após a cirurgia, confirmou que o cão estava livre de sinais clínicos. A cistite folicular foi relatada apenas em 1 cão no mundo, sendo esse considerado o primeiro relato no Brasil. Essa enfermidade deve ser considerada um diferencial para pacientes com doença refratária do trato urinário inferior de longa data. linfopenia hiperglobulinemia bacteriúria ultrassonografia cranial irregulares clavulânico AINEs fitoterápico tomentosa. tomentosa . tomentosa) acompanhamento cirurgia mundo Brasil data

ABSTRACT A 2-year-old English bulldog presented history of recurrent lower urinary tract disease, refractory to treatment. The Complete Blood Count revealed lymphopenia, hyperproteinemia, and hyperglobulinemia, while urinalysis indicated leukocyturia and bacteriuria. On the abdominal ultrasound, the bladder had a focal wall thickening in its cranial portion, as well as irregular echogenicity and internal margins. A bladder surgical biopsy was performed, indicating the presence of follicular cystitis. Clinical signs disappeared after treatment with a combination of amoxicillin and clavulanic acid, NSAIDs, supplementation with cranberry extract associated with cat's claw (Uncaria tomentosa). Clinical follow-up 12 months after surgery showed remission at all clinical signs. Follicular cystitis in dogs was reported only once worldwide, this case report is the first in Brazil; thus, it may be considered in the differential diagnosis for patients with refractory and recurrent lower urinary tract disease. 2yearold yearold 2 year old disease lymphopenia hyperproteinemia hyperglobulinemia bacteriuria ultrasound portion margins performed acid NSAIDs cats cat s Uncaria tomentosa. tomentosa . tomentosa) followup follow up 1 worldwide Brazil thus

RESUMO O presente trabalho teve por objetivo relatar um caso de linfoma leucemizado em um felino coinfectado com os vírus da imunodeficiência felina (FIV) e o da leucemia felina (FeLV). Foram realizados exames de hemograma, contagem de reticulócitos, mielograma, bioquímica, teste de imunocromatografia para FIV e FeLV, imunofluorescência indireta (IFA) para FeLV, radiografia torácica e citologia renal. Esse último exame revelou um linfoma extranodal. Foi determinante para a conclusão diagnóstica a associação dos sinais clínicos corroborados com a infiltração de elevada quantidade de células linfoblásticas na medula óssea, exibindo critérios citomorfológicos de malignidade, como mitoses atípicas, relacionadas à presença de corpúsculos linfoglandulares e material hematopoiético inter-relacionado. O linfoma é uma neoplasia relativamente comum em felinos, entretanto, a apresentação leucemizada é rara, podendo representar um desafio diagnóstico clínico, o que torna fundamental a inclusão da citologia medular na prática clínica dessa espécie.

ABSTRACT The present study aimed to report a case of lymphoma in leukemic phase in feline coinfected with feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV). Blood counts, reticulocyte counts, bone marrow avaluation, biochemistry, immunochromatography assay for FIV and FeLV, indirect immunofluorescence (IFA) for FeLV, thoracic radiography and renal citology were performed. This last examination revealed extranodal lymphoma. The association of the clinical signs with the infiltration of a high number of lymphoblastic cells in the bone marrow with cytomorphological criteria of malignancy, atypical mitoses, lymphoglandular corpuscles and hematopoietic material were determinant for the diagnostic conclusion. Lymphoma is a relatively common neoplasm in felines, however the leukemic phase is rare and may represent a clinical diagnostic challenge, making it essential to include bone marrow cytology in the clinical practice of this species.

RESUMO Este estudo relata um caso de coinfecção por Escherichia coli e Salmonella ser. Saintpaul em uma rolinha-roxa (Columbina talpacoti) recebida pelo Laboratório de Estudos Ornitológicos da Universidade Estadual do Ceará, Brasil. A ave apresentava diarreia, paralisia nas pernas e anorexia, indo a óbito rapidamente. A necropsia foi realizada e amostras de pulmão, rim, fígado e intestino foram coletados para isolamento microbiológico e análise histopatológica. Escherichia coli foi identificada em amostras de suabe cloacal, pulmão e rim. Salmonella ser. Saintpaul foi identificada no fígado e baço. Isolados de E. coli foram testados para a presença de oito genes de diagnóstico para patotipos diarreiogênicos (STEC, ETEC, EPEC, EIEC, EAEC) através de reação em cadeia de polimerase (PCR) convencional. EAEC foi detectada no pulmão e rim, e STEC foi identificada no intestino. Em conclusão, Columbina talpacoti é suscetível a infecção por Escherichia coli enteroagregativa e Salmonella ser. Saintpaul, o que pode implicar em risco para a saúde pública.

ABSTRACT This study reports a co-infection of Escherichia coli and Salmonella in a free-living ruddy ground dove (Columbina talpacoti) received at the Laboratory of Ornithological Studies of the State University of Ceará, Brazil. The bird presented diarrhea, leg paralysis and anorexia, and died shortly after. Necropsy was then performed and samples from lung, kidney, liver and intestine were collected for microbiological and histopathological analyses. Escherichia coli was isolated from cloacal swab, lung and kidney samples. Salmonella ser. Saintpaul was identified in liver and spleen samples. Escherichia coli isolates were tested for the presence of eight diagnostic genes for diarrheagenic pathotypes (STEC, ETEC, EPEC, EIEC, EAEC) with conventional polymerase chain reaction (PCR). EAEC was detected in the lung and kidney, and STEC in the intestine. In conclusion, Columbina talpacoti is susceptible to enteroaggregative Escherichia coli and Salmonella ser. Saintpaul infection, which may have public health implications.

The occurrence of canine externa otitis in Fortaleza-Ceará is reported. About 91.5% of the animals with clinical signs were positive to bacterial culture. Among all infections, 49.5% were mixed infections and the most common pathogens were Staphylococcus spp coagulase negative or positive and Pseudomonas aeruginosa. The most effective antimicrobials for Staphylococcus coagulase negative were: the quinolones, the aminoglicoside netilmycin and the beta-lactams, excepted ampicillin, penicillin and oxacilin; for Staphylococcus coagulase positive were: cefotoxin, amoxicillin + clavulanic acid, imipenem, netilmycin and cephatoxin; for Pseudomonas aeruginosa were: ciprofloxacin, tobramycin and imipenem.

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.

A total of 30 strains of Fusobacterium sp. isolated from gengival sulcus of 28 equines was studied in the period between January/1997 and April/1998. Bacterial isolation and antimicrobial resistance were determined by biochemical analyses and by the disk elution method. The species most frequently isolated was Fusobacterium nucleatum. The following resistance rates were observed: 10% for penicillin G, 87% for eritromycin, and 97% for sulfonamide. Theses results emphasize the need for monitoring the susceptibility patterns of this important bacterial group frequently isolated from normal sites in equines.
