“…All of the 12 Pseudomonas isolates were resistant to fusidic acid, and 7 were resistant to gentamicin. This differs from Tolar et al (2006) who found that 25 out of 25 P.aeruginosa isolates from canine corneal ulcers were sensitive to gentamicin however there are concerns that there is an increase in the resistance to the aminoglycosides by P.aeruginosa isolated from infected human eyes (Gelender et al 1984). This has important implications in the treatment of progressive corneal ulcers where gentamicin is indicated, and highlights the importance of therapeutic selection based on culture and sensitivity results.…”

“…The main genus of microorganisms isolated in ophthalmic changes animals are Staphylococcus (Prado et al, 2005); Wang et al, 2008), followed by Streptococcus, Pseudomonas and Escherichia coli (Tolar et al, 2006) In dogs, Staphylococcus pseudintermedius is identified as the main agente (Montiani-Ferreira et al, 2006).…”

The objective of this study was to identify the main microorganisms associated with ophthalmic infections and determine the resistance profile of these isolates against antimicrobial drugs. 26 bacterial isolates from 18 canine ophthalmic infections were submited to the phenotypic resistance profile for 36 drugs of 12 classes of antimicrobials, research of multidrug-resistant strains with importance in public health and detection of Staphylococcus mecA gene by PCR. The bacterial isolates were identified as Staphylococcus spp. (n = 18), Enterococcus spp. (n = 1), enterobacteria (n = 6) and Pseudomonas spp. (n = 1). The percentage of resistance and intermediate resistance were 42.48% (n = 325). Considering separate antimicrobials drugs, 18 isolates were characterized by multidrug resistant, while by the assesment of resistance to class, 20 isolates were multiresistant. In the phenotypic detection, 61.11% (11/18) of Staphylococcus spp. were predicted by Methicillin-Resistant Staphyloccus (MRS), whereas the genotypic detection, 38.89% (7/18) were carriers of the mecA gene. Two enterobacterias were considered producers of expectro Extended of Betalactamase (ESBL). EUCAST was more reliable for detecting MRS strains than the CLSI. The present study detected multiresistant isolates of great importance and are involved in cases of public health, such as MRS, MRSMLSb, ESBL, very important to be readily identified and controled so as to prevent the spread of this type of resistance.

“…The previous use of eye drops with antibiotics and steroids, administered as inadequate frequency or period, are associated with external eye diseases and can cause clinical recurrence, with selection and multiplication of eye microbiota, slow healing corneal epithelium, suppression of inflammatory mechanisms and enhancement of corneal ulceration (OLLIVIER, 2003;PRADO et al, 2006;TOLAR et al, 2006;LAUS, 2009;MORALES et al, 2009). …”

For the determination of the bacterial etiology of the external ocular diseases and sensitivity to antimicrobials, 38 dogs with external ocular diseases, unilateral or bilateral, and 120 dogs without ocular diseases (control group), were studied between 08/2008 and 07/2009 in the Veterinary Hospital of North Paraná State University, Brazil. The collected samples of the inferior conjunctival sac were incubated at 37ºC in an aerobic environment, in blood agar and MacConkey agar, for 120 hours. After the presumptive identification, the bacterial species were identified by the systems APISTAPH (bioMerieux, Incorporation), API 20 STREP (bio-Merieux, Incorporation) and BACTRAY (Laborclin, Ltd.) and incubated in Mueller-Hinton agar with antimicrobials disks, for sensitivity determination. For the risk factors, the owners answered a questionnaire with epidemiological variables. There was microorganism growth in 46 (73.02%) samples, with isolation of one microorganism in 42 samples and two microorganisms in four. Gram-positive bacteria corresponded to 76% of the isolated, Gramnegative 20% and yeasts fungi 4%. Staphylococcus spp totalized 66% of isolated, with S. aureus (24%) and S. intermedius (24%) the most prevalent. With the exception of S. intermedius (91.67%) and S. epidermidis (66.67%), the isolated bacterial species presented 100% resistance to the sulfonamide. The S. aureus isolated presented 91,67% sensitivity to chloranphenicol, tobramycin and amoxicillin/ clavulanic acid, and the same percentile of resistance to tetracycline. The S. intermedius presented 100% sensitivity to amoxicillin/ clavulanic acid and 91,67% to gentamicin and 75% resistance to tetracycline and ceftriaxone. The associations of risk for external ocular diseases were clinical returns (OR=59,50, 7,29
