Características laboratoriais das ceratites e conjuntivites causadas por Streptococcus sp

Abstract: Objetivos: Analisar os resultados laboratoriais de conjuntivites e ceratites com cultura positiva para Streptococcus sp, avaliando a incidência das diferentes espécies e os dados dos antibiogramas. Métodos: Estudo retrospectivo de revisão de prontuários de pacientes encaminhados ao laboratório de Doenças Externas do Departamento de Oftalmologia da UNIFESP com resultado de cultivo bacteriano positivo de córnea ou conjuntiva e com identificação de alguma cepa do gênero Streptococcus sp, no período de janeiro de … Show more

“…The incidence of Gram-negative bacilli was a little higher, which could be explained by geographical variation in the microbial flora of our patients (2,(14)(15)44) . The temporal analysis showed from 1975-93 to 1994-98 an increase in the frequency of gram-negative bacilli and a decrease in the frequency of gram-positive cocci, which from 1999 onwards remained stable.…”

“…According to the World Health Organization, the importance of corneal disease as a major cause of blindness worldwide remains second only to cataract (1) . Even though the diagnosis of infectious keratitis is usually presumptive and the treatment usually empirical, the laboratorial identification of the causative agent should always be pursued, in order to ensure a more specific treatment, to help guide eventual therapeutic modifications and to minimize any visual impairment due to a wrong or delayed diagnosis (2) . The incidence of different causative agents vary largely according to the geographical region, socioeconomic condition of the population and many individual factors such as contact lens use (3)(4)(5) , history of trauma (6)(7) or past ocular surgery (8)(9)(10)(11)(12)(13) , presence of comorbidities (14)(15)(16) , and age of the patient (17) , among many others.…”

“…Because of its location, the conjunctiva is exposed to several harmful agents, hence some pathogenic microorganisms (bacteria, viruses, rickettsias, fungi) can attack this mucous membrane causing infectious diseases (Nakano, 2002). Conjunctivitis is the ocular disease more common in the western hemisphere with the clinical severity ranging from a light hyperemia to a severe ocular necrotic wound (Solari, 2004). The simple bacterial conjunctivitis is a highly contagious infectious disease caused by the Gram positive cocci (e.g.…”

“…Normalmente, logo após o nascimento, se estabelece na superfície ocular uma microbiota balanceada e específica, devido a colonização ocular de microrganismos advindos da microbiota materna (no caso de parto natural, via vaginal) ou da microbiota anemófila (parto cesariana) que se mantém ao longo da vida (KAUFMAN et al, 2011). Com a recorrência de microrganismos implicados nas infecções oculares como a ceratite, conjuntivite, úlceras e endoftalmites, constatou-se que estas podem ser desencadeadas pela presença de espécies virulentas adaptadas ao sistema ocular, assim como por falha do mecanismo de defesa nessa região (SOLARI et al, 2004;GALVÃO;CASTRO, 2010).…”
