Alternative treatment in tits wounds in cows by using biological membrane (Biofill) | Tratamento alternativo de feridas de papilas mamárias de vacas através do emprego de membrana biológica (Biofill)
1996

This work evaluated the healing of experimentally provoked wounds in the tits of 16 nonlactant cows, by using a biological membrane that temporarily substitutes the skin, and by comparing it with the treatment with ointment. In each cow, the membrane was placed over the wound in the front tit of the right side, and the treatment with ointment was done in the hind tit of the right side, too. Clinical observations and histological analyses were performed on the 3rd, 7th, 14th and 28th days after the inflicting of the wound. From the observations it was possible to verify that tits treated with the biological membrane healed one week before those in the ointment-treated group. Furthermore the utilization of the biological membrane enables less frequent dressings.<br /><br /> | Neste trabalho, avaliou-se a evolução cicatricial de feridas provocadas experimentalmente em papilas mamárias de 16 vacas não lactentes, através do emprego de uma membrana biológica que substitui temporariamente a pele, comparando-a com tratamento à base de pomada epitelizante. Em cada animal, a membrana foi colocada na ferida da papila mamária anterior direita e o tratamento com pomada foi realizado na papila mamária posterior direita. Foram feitas observações clínicas e análise histológica no 39, 7S, 14s e 28s dias do pós-operatório. Das observações realizadas, verificou-se que as papilas tratadas com a membrana biológica cicatrizaram com uma semana de antecedência, quando comparadas às controle (pomada epitelizante). A utilização da membrana biológica permitiu ainda uma redução na<br />freqüência de curativos.

1996

In case of severe diarrhea, the clinical picture is worsenned by endotoxic shock. In order to evaluate the role of concomitant enteric bacterial infection or bacteremia, 34 dogs with hemorrhagic enteritis due to parvovirus infection were studied. Blood and fecal specimens were cultured, in an attempt to isolate enteropathogens, as well as Campylobacter jejuni. Electron microscopy was done for virus detection. Presence of parvovirus-like particles in the stools confirmed the diagnosis of parvovirus infection, but entheropathogens isolation attempts were unsuccessful. Neither Salmonella sp, nor enteropathogenic E. coli were isolated, while C. jejuni was cultured from five samples of feces from diarrheic dogs. Concerning hemoculture, Pseudomonas sp, E. coli, Alcaligenes odorans and a nonidentified labile non fermenter Gram-negative rod were isolated from severe cases of parvovirosis. Results allowed the conclusion that concurrent bacterial infection did not play an important role on the evolution of the process, but there was an<br />invasion of normal intestinal bacteria into the blood stream, leading to the installation of endotoxic shock in cases of fatal parvovirus infection.<br /> | O parvovírus canino pode estar associado a parasitas intestinais, vírus ou bactérias enteropatogênicas, os quais podem predispor ou contribuir para o agravamento do quadro mórbido e, nos casos de diarréia grave, na instalação do choque endotóxico. Com a finalidade de analisar a existência de infecção bacteriana concomitante ou de bacteremia,<br />em cães com enterite hemorrágica aguda e grave, causada por parvovírus, procedeu-se à coprocultura e à hemocultura, em 34 animais atendidos no Hospital Veterinário da FMVZ/USP. O diagnóstico clínico e etiológico de parvovirose baseou-se no perfil hematológico e na presença de partículas virais nas fezes dos cães, observadas por meio de<br />microscopia eletrônica. Não foram isoladas Salmonella sp ou E. coli enteropatogênica, ao contrário de Campylobacter jejuni, que foi isolado das fezes de cinco dos pacientes estudados. Em relação à hemocultura, Pseudomonas sp, E.coli, Alcaligenes odorans e bacilo Gram-negativo não fermentador, não identificado, foram isolados de cinco cães, dos quais quatro sofreram evolução fatal. Aparentemente, a infecção bacteriana concomitante não exerce papel de destaque na evolução do processo, mas existe uma invasão da corrente sangüínea por bactérias pertencentes à flora intestinal normal, o que resulta no agravamento do quadro mórbido, contribuindo para a instalação do choque endotóxico<br />e o óbito do animal.<br />
