Background: Invasion of the bloodstream by microorganisms constitutes one of the most serious situations in infectious disease. Microorganisms present in circulating blood whether continuously, intermittently, or transiently are a threat to every organ in the body. Prevalence and antimicrobial susceptibility of microorganisms vary depending upon the geography and the use of antibiotics. Methods: A cross-sectional study to determine the prevalent organisms causing bloodstream infection was conducted. BACTEC BD 9050 system was used to identify the causative organism, and sub-cultures were done on MacConkey Agar and Blood Agar. Antibiotic susceptibility test (AST) was done using Kirby B Disk diffusion method. Results: A total of 170 patients were enrolled, and blood samples of 53 patients showed growth of organisms. Staphylococcus aureus was the most commonly isolated organism. Most of the Gram-positive cocci (GPC) were susceptible to vancomycin and linezolid. Most of the Gram-negative bacilli (GNB) showed sensitivity to cefoperazone/sulbactam followed by imipenem.
A total of 14 phenotypically similar clinical isolates of Klebsiella pneumoniae, resistant to multiple drugs including cefotaxime and ceftazidime, were isolated from blood of neonates admitted to neonatal intensive care unit (NICU) within a short span of 10 days. Alarmed at the possibility of occurrence of outbreak, a thorough investigation was done. Microbiological sampling of the NICU and labour room (LR) environment yielded 12 K. pneumoniae isolates. The presence of extended spectrum β-lactamase (ESBL) in the clinical and environmental strains was detected by double-disk synergy test (DDST), CLSI phenotypic confirmatory disk diffusion test (PCDDT) and E-test ESBL strips. Amp-C screen (disk) test was done to determine Amp-C β-lactamase production. 100% clinical strains, 57% NICU strains and 80% LR strains were ESBL positive. 57% clinical, 43% NICU and 20% LR strains were Amp-C screen positive. Polymerase chain reaction (PCR) of representative ESBL positive (10 clinical and 5 environmental) strains showed CTX gene and TEM and/or SHV gene in all. K. pneumoniae showing multiple mechanisms of drug resistance was responsible for the outbreak.
A case of invasive Trichosporonosis due to Trichosporon asahii in an otherwise healthy young adult male presenting as meningoencephalitis and pneumonia is reported here. T. asahii was isolated from cerebrospinal fluid and sputum of the patient and morphologic forms of organism was also demonstrated on direct Gram stain of sputum. The isolate was identified as T. asahii. The patient partially responded to fluconazole therapy. Our case suggests that T. asahii can no longer be linked with Trichospronosis in immunocompromised patient alone and any case of meningitis needs thorough mycological workup for its correct etiological identification and appropriate management.
Background: Infertility is increasingly becoming a significant health problem in many areas of the world. The infection which is caused by Chlamydia trachomatis is a major cause of tubal factor infertility secondary to salpingitis. However, the data which pertains to infertility attributed to the C. trachomatis infection is limited in India.
Aims:To evaluate the chlamydial infection in women who suffered from infertility and to investigate the possible role of the chlamydia serology as a screening test for tubal infertility.Method: This study was aimed at evaluating the chlamydial infection in fifty women with primary infertility and at investigating the possible role of the chlamydial serology as a screening test for tubal infertility, by the detection of the anti-chlamydial IgM antibodies by using E.L.I.S.A.
Setting and Design:The present prospective study was carried out at a tertiary care hospital in north India.
Results:In this study, a high seropositivity (60%) for the antichlamydial antibody was observed. 52% females showed bilateral tubal blockage, while the most common site of the blockage was the ampullary portion (36%).
Conclusion:These findings highlighted a strong correlation between the tubal factor infertility and the antichlamydial antibodies. It also stressed on the need of the screening of infertile women for C. trachomatis with laboratory investigations, which could provide a rapid and specific diagnosis so that early therapeutic interventions could be instituted.Ashish surAnA, VijAylAtA rAstogi, Prem singh nirWAn
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
