AbstractIn the last two decades, group B streptococcus (GBS) infection has established itself as a major cause of perinatal morbidity and mortality. The purpose of this study is to identify if the electively induced labor with oxytocin in women with positive cultures of Streptococcus agalactiae, namely the group B streptococcus (GBS), helps the mother and fetus and decreases the risk associated with perinatal transmission of GBS compared with the spontaneous labor. Results associated with induction of labor with oxytocin compared with spontaneous labor in pregnant women who have GBS - positive cervical cultures, are also used to determine whether induction of labor decreases the risk of complications from GBS infection.

Consequence of Streptococcus agalactiae, Group B Streptococcus (GBS) relating infant’s diseases are well documented. Although many women carry this bacterium in their vagina, they may transfer to their infant during delivery and may result in different neonatal invasive diseases. The aim of this study was to determine the prevalence of GBS and serotyping the isolated species among un-selective non-pregnant women who attended two gynecology clinics in Tehran. In this cross-sectional study, a total of 560 vaginal samples collected from non-pregnant women. Following inoculation of the specimen on Blood Agar, the standard technology was applied for the final identification of GBS. Detected GBS species were further confirmed using specific PCR directed on dlts gene. Capsular serotyping was done by using the multiplex PCR method. The chi-square method was used for statistical analysis. Fifty (8.9%) out of 560 non-pregnant women were carriers of GBS. The most common types were III (36%), followed by type II (32%), Ia (26%), and Ib (6%), respectively. Results represent that the prevalence rate of GBS in non-pregnant women was reliable and similar to what obtained from pregnant women. In addition, the serotype III was found the most dominant types, as well as other investigations in the Tehran area. Therefore, vaccine designation based on type III is recommended.

Group B streptococcus (GBS), or Streptococcus agalactiae, has been a continuing focus of debate in the paediatric and obstetric worlds. The organism has emerged as the leading cause of early-onset neonatal sepsis. With an average of 20% of mothers being carriers for the organism (range from 15–40%), the following questions remain to be answered:1 How best to screen for GBS and which protocol to use?2 How best to counsel patients who are GBS carriers?3 What is the cost effectiveness of the screening protocols?

Abstract Background: Group B streptococcus (Streptococcus agalactiae) is one of the most common pathogens causing meningitis, bacteremia and pneumonia. The drug resistance mechanisms of group B streptococcus in different countries and regions also show regional differences.Method: The study population was comprised of 1877 pregnant women of 34-38 weeks who underwent prenatal examination in the gynecology and obstetrics outpatient clinic of Xinjiang People's Hospital, between January 1, 2019 and January 31, 2020. Clinic specimens were collected and identified by the API bacteria Rapid Identification card for the downstream group B Streptococcus (Streptococcus agalactiae) isolation. Drug susceptibility of the Streptococcus agalactiae isolated was detected by Kirby-Bauer disk diffusion method. Macrolide–lincosamide–streptogramin B (MLSB) resistance was determined by D test. Real-time quantitative polymerase chain reaction and Gene sequencing was performed for the resistance genes ermA, ermB, mreA, erm (47), mefA/E and Lin B.Results: 149 Streptococcus agalactiae-positive strains were identified by clinical isolation, with a positive rate of 7.94%. Group B Streptococcus showed 100% susceptibility to linezolid, penicillin, vancomycin, meropenem, ampicillin, ceftriaxone, 44.97%, 35.57%, 56.38% and 29.53% susceptibility to levofloxacin, erythromycin, tetracycline and clindamycin, respectively. Among the 149 isolates, 127 strains showed macrolide resistance phenotype. The detection rate of intrinsic resistance phenotype (cMLS) was 40.94% (59/127), active efflux resistance phenotype (MS) 9.45% (12/127), and induced resistance phenotype (iMLS) 22.83% (29/127).Conclusion: The ermB gene-mediated 50s ribosome target site change co-existing with mreA gene for macrolide resistance efflux may play a major role in the mechanism of Streptococcus agalactiae resistance macrolide resistance of in perinatal women in Xinjiang. The change of 50s ribosomal target site mediated by ermB gene may be the main reason for drug cross-resistance.

Abstract Introduction/Objective Streptococcus agalactiae, Group B Streptococcus (GBS), is a major cause of neonatal sepsis and infections in pregnant women. However, incidence of invasive GBS infections has more than doubled in the last two decades with highest risk in adults 65 years or older. Other risk factors are diabetes, malignancy, and immunocompromised state. Bacteremia and skin soft tissue infections are the most common invasive infections in nonpregnant adults. Rarely GBS infection has a fulminating pyrogenic exotoxin-mediated course characterized by acute onset, multiorgan failure, shock, and sometimes death, referred to as toxic shock-like syndrome. Methods A 77-year-old hypertensive female with uncontrolled type 2 diabetes mellitus and a history of bilateral foot ulcers presented to the hospital in probable septic shock. Clinical diagnosis of necrotizing fasciitis was made and she underwent bilateral lower limb amputations. Results Grossly soft tissue appeared gray. Microscopically fascia was necrotic without neutrophils present and Gram stain revealed sheets of Gram positive cocci. These findings reflected histopathologic Stage III necrotizing fasciitis, which is associated with 47% mortality. Autopsy showed a similar histology of Stage III necrotizing fasciitis involving the surgical stump. Erythema and desquamation of the upper limbs bilaterally and multi-organ failure met the clinical picture of Streptococcal Toxic Shock Syndrome (STSS) and fulfilled the criteria for TSS due to Group A Streptococcus (GAS), defined by The Working Group on Severe Streptococcal Infections. Conclusion Group B Streptococcal Toxic Shock-Like Syndrome may have a similar outcome to STSS caused by GAS and other pathogens and, in limited studies, mortality has been 30% or greater.

Abstract Background Influenza in pregnancy is associated with elevated morbidity and mortality. Influenza vaccines are both safe and effective in pregnancy, supporting routine use in this population. Even though influenza vaccination in Mexico is recommended for pregnant women, there are no publications of influenza vaccine coverage in pregnancy. This is the first Latin American survey done only in physicians aiming to assess the knowledge, beliefs, and attitudes that Mexican Obstetrics-Gynecologists (OBG) and Family Physicians (FP) have towards influenza and influenza immunization during pregnancy. Methods A cross-sectional survey was conducted, both paper-based and online. The questionnaire was composed of 35 questions, which addressed general knowledge of influenza, recommendations for vaccination during pregnancy, and beliefs and attitudes concerning the acceptability of the vaccine in pregnant women. Results A total of 206 completed surveys were available, 98 (47.6%) from OBG, 108 (52.4%) from FP. Regarding current practicing medical institutions, 76 (37%), 69 (34%), 31 (14.5%), 30 (14.5%) reported working for the Mexican Institute of Social Security, Private Sector, Secretariat of Health, or a combination of all respectively, representing an estimated 2,472 daily pregnancy consultations. About a quarter (26.2%) reported not having a notion that influenza is more severe among pregnant women. More than half (51.5%) ignored the potential side effects of influenza infection on the fetus. The majority (56.8%) did not know when vaccination during pregnancy should occur. Pregnancy as a risk factor for developing influenza complications was known only in 48.1%. Also, 46.1 % believed that vaccination only confers protection to the mother, but not to the fetus. Nevertheless, 96.1% considered that immunization against influenza during pregnancy is a safe and effective preventive intervention. A results’ summary is shown in Figure-1. Conclusion Based on this survey, current knowledge of OBG and FP for influenza morbidity and mortality during pregnancy, and the importance of influenza vaccination in pregnant women, is poor. Mandatory recommendations to educate medical providers regarding influenza vaccination during pregnancy in Mexico are necessary, even as imperative for CME credits.
