| ABSTRACT Background: Infections caused by Chlamydia trachomatis and Neisseria gonorrhoeae are the most common bacterial sexually transmitted infections throughout the world. These sexually transmitted infections are a growing problem in people living with HIV/AIDS. However, the presence of these agents in extra genital sites, remains poorly studied in our country. The objective of this study was to estimate the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae anal and genital infection in people living with HIV/AIDS followed in a reference center in Salvador, Brazil. Methods: Cross-sectional study, from June 2013 to June 2015. Proven HIV-infected people attending this reference center were invited. Clinical and epidemiological data were... |

| This study compares the detection rates of Chlamydia trachomatis by two techniques, direct immunofluorescence (IMF) and real time polymerase chain reaction (PCR), in patients with and without intra-epithelial cervical lesions (SIL) in Recife. We conducted a transversal study involving 35 women with SIL and 35 without SIL attended at Ambulatório Especializado da Mulher, Recife, Brazil. They were tested for Chlamydia trachomatis using two techniques, direct IMF or real time PCR. The rates of Chlamydia trachomatis detection were compared and the association with intra-epithelial cervical lesions was determined using the chi-square test at a 5% level of significance. Concordance between the tests was evaluated using kappa. The global prevalence of Chlamydia... |

| Objectives: High-risk types of human papillomavirus (HPV) are strongly associated with cervical cancer (CC), and Chlamydia trachomatis (CT), the most frequent sexually transmitted bacterial infection (STBI) worldwide, seems to be a risk factor for HPV infection and for CC. It is also known that both agents are more prevalent in vulnerable communities where lack of adequate primary health care is a cause for concern. The aim of this work was to determine the impact of CT and HPV infections in women belonging to an isolated aboriginal population (Pilaga community) from a poor region in Northern Argentina (province of Formosa). For this purpose, a cross-sectional study was performed in all sexually active Pilaga women, who attended a local community-based... |

| This was a cross-sectional study aimed to determine the prevalence of and to identify risk factors for Chlamydia trachomatis (CT) among human immunodeficiency virus (HIV)-infected women attending the acquired immunodeficiency syndrome (AIDS) clinic in the city of Manaus, Brazil, in 2009-2010. Participants answered a questionnaire containing demographic, epidemiological, and clinical data. A genital specimen was collected during examination to detect CT-DNA by hybrid capture, and blood samples were taken to determine CD4+T and HIV viral load. There were 329 women included in the study. Median age was 32 years (IQR = 27-38) and median schooling was nine years (IQR = 4-11). The prevalence of CT was 4.3% (95%CI: 2.1-6.5). Logistic regression analysis showed... |

| Chlamydia trachomatis is now one of the most prevalent bacteria found in classic sexually transmissible diseases (STD), and as such, constitutes a serious public health problem. We examined the prevalence of Chlamydia trachomatis, by polymerase chain reaction (PCR), in 121 sexually active women who sought treatment for STD in the Alfredo da Matta Institute of Dermatology and Venerology and the Institute of Tropical Medicine of Amazonas in Manaus, Brazil. These women were examined by a specific PCR for the chlamydial plasmid, and the nature of the amplicon was determined by restriction analysis and DNA sequencing. The PCR diagnosis revealed a prevalence of 20.7% infected women. |

| The shipment and storage conditions of clinical samples pose a major challenge to the detection accuracy of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Ureaplasma urealyticum (UU) when using quantitative real-time polymerase chain reaction (qRT-PCR). The aim of the present study was to explore the influence of storage time at 4°C on the DNA of these pathogens and its effect on their detection by qRT-PCR. CT, NG, and UU positive genital swabs from 70 patients were collected, and DNA of all samples were extracted and divided into eight aliquots. One aliquot was immediately analyzed with qRT-PCR to assess the initial pathogen load, whereas the remaining samples were stored at 4°C and analyzed after 1, 2, 3, 7, 14, 21, and 28 days. No... |

| OBJECTIVE: To evaluate the effect of Chlamydia trachomatis infection during pregnancy on perinatal morbidity and mortality. METHODS: Systematic review and meta-analysis in an electronic database and manual, combining high sensitivity specific descriptors seeking to answer the research objective. The articles considered to be of high methodological quality (score above 6 on the Newcastle-Ottawa Scale) were assessed by meta-analysis. RESULTS: Summary estimates of 12 studies were calculated by means of Mantel-Haenszel test with 95% confidence interval. It was observed that Chlamydia infection during pregnancy increased risk of preterm labor (relative risk (RR) = 1.35 [1.11, 1.63]), low birth weight (RR = 1.52 [1.24, 1.87]) and perinatal mortality (RR = 1.84... |

| The incidence of sexually transmitted diseases among adolescents is increasing worldwide. Genital Chlamydia trachomatis infection is one of the most prevalent sexually transmitted diseases in young women, and undetected disease is highly associated with long-term complications in women. Our goal was to determine the prevalence of cervical Chlamydia trachomatis infection in a sexually active population of female adolescents from Salvador, Brazil, and to describe their socio-demographic, behavioral, and clinical characteristics. 100 sexually active adolescents (10-19 years) were included in this study, between 2008 and 2010. Endocervical samples were obtained during gynecological examination. Inhouse polymerase chain reaction of cervical specimens was used... |

| Abstract Background: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) cause infections in the female genital tract, increasing susceptibility to and infectiousness of HIV. The objectives of the present study were to determine the prevalence and associated factors of CT and GC infection among HIV-infected women in Brazil. Methods: Cross-sectional study conducted from March to December 2015, including HIV-infected women attending referral centers in nine states of Brazil, aged 18-49 years, nonpregnant. An interview was conducted including socio-demographic, epidemiological and clinical characteristics. After the interview, gynecological examination was conducted to collect cervical cytology and vaginal secretion to C. trachomatis and N.... |
