Study of post caesarean section wound infection and microbiological epidemiology in tertiary care centre, Western Rajasthan, India

Background: Surgical site infection (SSI) following C-section is a common encountered problem and needs to be analysed. In this study we have determined the incidence, risk factors and common bacterial pathogens in surgical site infection (SSI) following C-section at a tertiary care centre.Methods: A hospital based prospective study conducted for a period of 6 months. Those women whose C-section was complicated by SSI within 5 days postoperatively were included in the study. Risk factors for SSI were identified and microbiological pattern was studied.Results: Out of 62 women whose C-section was complicated by SSI within 5 days post-operatively, during this study period post caesarian SSI incidence was 0.34%. In this study post C-section SSI found as high as 43.55%, in lower socio-economic status. Among all patients, un-booked were 62.90%, Referred patients were as high as 67.74%. SSI developed in 69.35% patients without preoperative antibiotic prophylaxis. C-section done in PROM in 64.50% and as an elective emergency 79.03%, blood transfusion needed in 59.68% and type of incision being transverse (Pfannenstiel) in 88.71%. Subcutaneous suture technique used in 75.81% and secondary healing occurred in 67.74%. Most common organism grown was CoNS (coagulase negative staphylococcus) 29.03% in SSI.Conclusions: To reduce SSI, the hospital infection control system and surgical site infection surveillance program has to be established. Knowing the prevalence and risk factors will help optimal precaution and standard surgical technique to reduce SSI, which causes increased hospital stay of patients.

A comparative analysis of micro-organism colonization of tooth-brushes in a public bath based on the storage technique / 대한구강보건학회지

OBJECTIVES: Bacterial colonization on toothbrushes can cause stomatitis and other oral diseases such as dental caries and periodontitis. In this study we tested 18 toothbrushes, of which six were left exposedto the air, six were stored in a plastic bag, and six in a toothbrush case. METHODS: ATP (RLU: relatively light unit) values measured by ATP Luminometer were compared with APC (CFU: colony forming unit) by swabbing culture method using 3M™ petrifilm™ aerobic count plates. RESULTS: Swabs from toothbrushes left exposed in the air developed an average of 651.67±261.94 CFU, while the “In plastic bag” and the “In toothbrush case” specimens developed 593.17±354.33 and 120.83±68.87 CFU, respectively. CONCLUSION: The best option is to rinse the toothbrush well with water and to keep them dry in a well-ventilated area in order to reduce the growth of bacteria in a public bath.

The Effects of Teatree Oil Gargling on Oral Cavity Micro-Organism Growth and Perceived Discomfort of Patient Receiving Chemotherapy / 성인간호학회지

PURPOSE: The study is to investigate the effects of tea tree oil gargling on oral cavity micro-organism growth and on the perceived discomfort of patients receiving chemotherapy. METHODS: A nonequivalent control group non-synchronized design was used to determine the effects of tea tree oil gargling on oral cavity for 20 second after using it for one week, twice a day. The sample consisted of two groups of patients receiving chemotherapy : 19 patients in experimental and 20 patients in control group. The instruments used in the study were Oral Assessment Guide(OAG), a measure of perceived symptoms on oral cavity, and a test of oral mucosal micro-organism culture. The data were analyzed using chi-square test, repeated measure of ANOVA, and Pearson correlation coefficient. RESULTS: There was no significant difference between the two groups in micro-organism culture test of oral mucosa. The experimental group showed a lower number and fewer kinds of micro-organisms than the control group. CONCLUSION: It is considered that use of tea tree oil is effective in infection control of the oral cavity.

Research Progress on Degradation of Triazophos / 环境与健康杂志

With the wide application of triazophos in agricultural production, increasing attention has been paid to the contamination of this pesticide to the environment. The studies on triazophos residue and degradation have made certain progress in recent years.This paper gives an outline of micro-organisms degrading triazophos and the possible pathways by which they degrade this pesticide. The reaction kinetics and mechanisms of triazophos hydrolysis and photolysis are also reviewed briefly.

THE SEASONAL DYNAMICS OF SOIL MICROBIAL NUMBER AND RESPIRATION RATE IN HEPTACODIUM MICONIOIDES COMMUNITY / 微生物学通报

The seasonal dynamics of the soil microbial growth and soil net respir ation rate were studied in the imminent Heptacodium miconioides community T he results indicate that the numbers of bacteria and actynomices of rhizosphere soil or that of bacteria ,fungi and actynomices of non rhizosphere soil as well as net respiration rate of soil maintain similar seasonal dynamics in which dis play mono peak curves and their biggest values occure in September but the bi ggest nu mber of fungi of rhizosphere soil is in October The microbial numbers of soil,e s pecially that of soil fungi ,are greatly affected by the water content and tempe rature of soil The net respiration rate of soil closely relate not only with t h e water content and temperature of soil,but also with the soil microbial numbers of non rhizosphere soil which are mostly responsible for the net respiration r ate of soil
