RESUMO
Acinetobacter sp isolates deserve special attention once they have emerged globally in healthcare institutions because they display numerous intrinsic and acquired drug-resistance mechanisms. This study assessed the antibiotic susceptibility profile, the presence of the genetic marker blaOXA-23, and the clonal relationship among 34 nosocomial isolates of Acinetobacter spp obtained at a hospital in southeastern Brazil. Antibiotic sensitivity analysis was performed by the standard disc-diffusion method. All isolates were found to be extensively resistant to several drugs, but sensitive to polymyxin B. A polymerase chain reaction (PCR) assay was used to detect the blaOXA-23 gene, which is associated with carbapenem resistance. The genetic profile and the clonal relationship among isolates were analyzed via enterobacterial repetitive intergenic consensus (ERIC)-PCR. The Acinetobacter spp were divided into four groups with 22 distinct genetic subgroups. ERIC-PCR analysis revealed the genetic diversity among isolates, which, despite having a heterogeneous profile, displayed 100% clonality among 56% (19/34) of them.

We report a case of penile myiasis in a Brazilian man caused by the larva of Dermatobia hominis. Myiasis is a parasitic disease of humans and other vertebrates caused by larvae of several fly species. Although urinary myiasis is well recognised, infestation of the genital tissue is a rare occurrence. Once the diagnosis has been made, the treatment is usually straightforward and uncomplicated.

Myiasis is a parasitic infestation caused by larvae of several fly species. Diagnosis and treatment are simple. This infestation is, however, rarely seen in the vulvar area. We present a short review of the disease and the case of a 19-year-old pregnant girl with vulvar myiasis and concomitant syphilis, vaginal trichomoniasis and genital candidiasis. The patient was also positive for human immunodeficiency virus.

A miíase é uma infecção parasitária causada por larvas de diversos tipos de moscas. Embora o reconhecimento e tratamento sejam fáceis, constituem uma infecção pouco freqúente na região vulvar. Este estudo apresenta uma revisão a respeito da patologia por miíase e a descrição do caso de uma adolescente de 19 anos, gestante, portadora de miíase vulvar associada à tricomoníase, candidíase e sífilis, além se ser soropositiva para HIV.
