Klebsiella pneumoniae blaNDM-1 carrying a class 1 integron causing a hospital outbreak in a Mexican attention center.

Introduction: Infections acquired in hospitals are the cause of high morbidity and mortality and with the emergence of resistant bacteria, the problem is greater. The aim of this work was to determine the genetic characteristics and timeline of Klebsiella pneumoniae blaNDM-1 carrying a class 1 integron involved in an intrahospital outbreak.

Methodology: Investigation was made from the first detection of K.

Prospective study of urinary tract infection surveillance after kidney transplantation.

Background: Urinary tract infection (UTI) remains one of the main complications after kidney transplantation and it has serious consequences.

Methods: Fifty-two patients with kidney transplantation were evaluated for UTI at 3-145 days (mean 40.0 days) after surgery.

[Benefits of Affirm VPIII and L-PAP in the diagnosis of bacterial vaginosis].

Introduction: Bacterial vaginosis is a syndrome occurring in women of reproductive age, characterized by abnormal vaginal discharge and associated with gynecological and obstetric problems during pregnancy.

Aim: This study assesses the value of proline aminopeptidase (L-Pap) detection and DNA hybridization with the Affirm VPIII microbial identification test, as analytical tools for the diagnosis of bacterial vaginosis.

Material And Methods: Vaginal secretions from 406 women were collected and analyzed to investigate bacterial vaginosis with the Affirm VPIII commercial kit and the L-Pap reaction.

Comparative study of the antimutagenic properties of vitamins C and E against mutation induced by norfloxacin.

Background: Norfloxacin like other fluoroquinolones, is known to mbe mutagenic for Salmonella typhimurium TA102 strain. This mutagenic effect is due to free oxygen radicals (ROS), because it is inhibited by antioxidants such as beta-carotene and naturally occurring antioxidants of Roheo discolor and other plants. The aim of this work was to evaluate combination therapy with norfloxacin and vitamins C and E, to reduce the possible genotoxic risk associated with fluoroquinolones.

[Identification of Candida species causing vaginitis in Mexican patients].

Introduction: The increasing frequency of candidiasis due Candida spp. other than C. albicans suggests that these organisms may also have emerged as a cause of vaginitis.

A new test of disk-diffusion to help in staphylococci identification.

A modified carbohydrate fermentation test (MCFT) of disk-diffusion assay was performed using a peptone-free agar medium, in order to improve the identification of clinical staphylococci species. Results were compared with the standard method of carbohydrate fermentation in tubes (SCFT) containing methyl red broth. MCFT was able to identify correctly 12 different species of staphylococci from the ATCC collection and 646 clinical isolates.

[Etiology of cervical vaginal infection among patients of the Juárez Hospital of Mexico].

Objective: To identify the etiologic agents of cervicovaginal infection in order to establish an accurate diagnosis and proper treatment.

Material And Methods: From January 1995 to December 1999, bacteriological studies were done in cervical discharge specimens from 6,811 patients aged 13 to 65 years, seen at Hospital Juarez in Mexico City. All patients had leucorrhea, pruritus, hyperemia, and abdominal pain.
