Microbiota Conjuntival Em Cães Clinicamente Sadios E Cães Com Ceratoconjuntivite Seca

Abstract

Este trabalho objetivou determinar os microrganismos bacterianos no saco conjuntival de cães clinicamente normais e cães com ceratoconjuntivite seca (CCS), atendidos no Hospital de Medicina Veterinária da Universidade Federal da Bahia. Foram incluídos na pesquisa 30 animais sadios e 28 com CCS. Foi observado crescimento bacteriano em 60% das amostras oculares dos cães sadios e em 89,29% dos cães com CCS. Houve predomínio de espécies Gram positivas em ambos os grupos. Nos animais normais as bactérias mais prevalentes foram Staphylococcus intermedius (26,83%), seguido por Staphylococcus aureus (21,95%) e Staphylococcus epidermidis (19,51%). Houve identificação de leveduras em 38,34% das amostras. Dos 30 animais sadios estudados, 46,66% apresentaram cultura positiva bilateral, 26,67% cultura positiva unilateral e 26,67% cultura negativa. Nos animais com CCS, as bactérias de maior prevalência foram o Streptococcus β-hemolítico (16,13%), seguido por Staphylococcus intermedius (12,90%) e o Staphylococcus aureus (11,83%). Ocorreu identificação de leveduras em 19,64% das amostras. Dos 28 animais com CCS, observou-se que 82,14% apresentaram cultura positiva bilateral e 17,86% cultura positiva unilateral.

Multidrug-Resistant Bacterial Pathogens Assessment in Canine Ophthalmic Infections

“…This study showed similar results to those found by Oria et al (2013) to the identification of bacterial types involved in ophthalmic infections which were 64.51% of the samples identified as being Gram-positive and 35.48% Gram-negative. When compared to the identification of the bacterial genus, the present study found similar numbers to Zacarias Junior et al (2012) for Staphylococcus (66%), but higher than Oria et al (2013) with found 38%, however, similar numbers for E. coli and Enterobacter spp., 27.27% and 18.18% respectively.…”

As Santos et al The predominance of Gram-positive isolates is because staphylococci is part of the resident flora of the mucosa and skin, so when there is an imbalance between the agent and the host, these microorganisms can become pathogenic (Prado et al, 2005;Wang et al, 2008).…”

Bacterial culture and antibiotic sensitivity from the ocular conjunctiva of horses

“…Similar findings were respectively reported by SANTOS et al (2009) andFOTI et al (2013) in studies with dogs and horses with healthy eyes. JOHNS et al (2011), meanwhile, reported the genus Acinetobacter as the most representative for the group of gram-negative bacteria, and did not identify Proteus mirabilis in their study.…”

“…The grampositive bacteria displayed a predominance of 86.6% among the strains isolated, in accordance with findings for a series of domestic and wild animals (PRADO et al, 2005;SANTOS et al, 2009;SPINELLI et al, 2010;BONELLI et al, 2014;ORIÁ et al, 2014).…”

“…In different animal species, including horses (ANDREW et al, 2003;JOHNS et al, 2011), mules (TAMARZADEH & ARAGHI-SOOREH, 2014), donkeys (FOTI et al, 2013), sheep (BONELLI et al, 2014), dogs (PRADO et al, 2005) and rabbits (ORIÁ et al, 2014). Bacterial population often isolated from healthy eyes is composed of gram-positive bacteria, although strains of methicillin-resistant to Staphylococcus (MRS) and gran negative strains, have also been identified (SANTOS et al, 2009;JOHNS et al, 2011;WILLCOX, 2013;MOUNEY et al, 2013). Some eye infections, however, can be caused by resident microorganisms, which become potentially pathogenic after their virulence is increased by external factors, such as trauma, stress, aging and reduction in commensal microbiota (COGEN et al 2008;WILLCOX, 2013).…”
