“…As well, our finding is agreed with a recent similar study done by 22 who studied central venous catheter colonization and blood stream infection in a tertiary teaching hospital in India and revealed that negative staphylococci was the most common organism found causing central related blood stream infection. Moreover ,our finding was agreed with the results of previous studies done by 23 – 25 that have found that a dominance of Gram-negative bacteria that may be related to the colonization of the hands of healthcare providers.…”

Background: Central line-associated bloodstream infections continue to be one of the most important health problems in ICU. Objectives: To identify the central line-related bloodstream infections and their microbiological characteristics Specific objectives to the identify the incidence, predisposing factors of central line-related bloodstream Infections and study the antibiotic sensitivity patterns of the isolated organisms. Material and Methods: Patients’ demographic, clinical data, central venous catheter related data,and blood culture specimen collection data were collected utilizing a descriptive exploratory design from a purposive sample of 120 ICU patients under- went insertion central venous catheter. Results: out of 120 central line catheters sent for culture from patients immediately and seven days after insertion., 13( 10.83%) were positive seven days after insertion. Of the 13 infection cases, 10 cases were Staphylococcus epidermis and the others were Staphylococcus aureus. In addition, most infected patients were overweight and obese, diabetic, had sub-clavian route, and their length of hospital stayed more than7 days. Conclusion: 10.83 % developed bacterial blood stream infection 7 days after insertion of central venous catheters, and most of bacterial isolates were Staphylococcus epidermis and were sensitive to Vancomycin and Amikain. Keywords: Bacterial infections; bacterial isolates; antibiotic resistance.

“…27 The PCR findings of this study indicated colonization of catheters, a prerequisite for catheter-related bloodstream infection. [28][29][30] The presence of bacteria in the tips in the cultures from catheter tips is a warning and calls for greater clinical awareness of the risk of CVC-associated infections. 8 An opinion about the diagnostic criteria for catheter-related bloodstream infections pinpointed the following limitations: blood cultures were not always performed; prior antimicrobial treatment may have prevented the growth of bacteria in the culture; collected blood volume; intermittent release of bacteria into the blood; and delayed transport or arrival of blood at the laboratory.…”

Background: Central venous catheter–related bloodstream infection is an important adverse event in health care. Molecular methods are not yet substitutive of microbiological in the detection of the pathogens responsible for the infection, but they can help in the epidemiological characterization. Aim: To detect bacteria by polymerase chain reaction, from material extracted from the tip of central catheters of patients suspected of infection at the intensive care unit. Methods: Catheters (n = 34) of patients suspected of central venous catheter–related infection were analyzed by polymerase chain reaction. The findings were compared with culture of catheter tip and blood cultures performed by the hospital. Findings: The prevalence of bacteria was Staphylococcus aureus (50%), Enterococcus faecalis (41.2%), Klebsiella pneumoniae (32.4), Pseudomonas aeruginosa (20.6%), Acinetobacter baumannii (38.2%), Escherichia coli (2.9%), and Enterobacter cloacae (0%). No blood culture showed bacterial growth, the culture of catheter tip revealed bacteria in 21 (61.8%) and the polymerase chain reaction had positivity in 31 (91.2%) of the catheters. The mean central venous catheter time was 11 days, and the jugular vein was the site of insertion. Conclusion: The molecular method identified more bacteria than microbiological methods and revealed colonization of the catheters. The most commonly found bacteria are in the environment and in the microbiota of the skin, which suggests contamination by the hands of health professionals and points out the need for more efforts in preventive strategies.
