Objective: To understand the awareness of chikungunya fever knowledge and its related factors among medical college students in Baise City, so as to provide a scientific basis to offer relevant courses and special education. Methods: From July to August 2025, 7 286 enrolled medical students were selected by a sampling method from a medical college in Baise City to participate in the questionnaire survey. The questionnaire covered epidemiological characteristics, clinical symptoms, and prevention/control knowledge of chikungunya fever. Statistical analyses including the Chi quare test and multivariate Logistic regression models were performed. Results: The overall awareness rate of chikungunya fever knowledge among the medical students was 18.89%. Among the knowledge items, the awareness rate of "the high incidence season" was the highest (84.05%), while that of "the infectious period" was the lowest (17.80%). Multivariate Logistic regression analysis showed that medical students with female (a OR= 1.37 , 95%CI =1.20- 1.57 ), the age for over 25 years old (a OR=1.76, 95%CI =1.05-2.93), whose father had a middle school educational level (a OR=1.18, 95%CI =1.05-1.31), and majored in preventive medicine (a OR=1.54, 95%CI =1.10-1.67) had relatively higher awareness rates of chikungunya fever knowledge (all P <0.05). In contrast, students of Zhuang ethnicity (a OR= 0.87 , 95%CI =0.76-0.98) and majoring in nursing (a OR=0.74, 95%CI =0.61-0.91) or pharmacy (a OR=0.70, 95%CI =0.52-0.95) had relatively lower awareness rates (all P <0.05). Conclusions The awareness rate of chikungunya fever related knowledge among medical college students in Baise City is relatively low. Schools should take targeted publicity measures to improve medical students awareness.

Objective To analyze the virulence genes expression and drug resistance situation of type three secretion system (TTSS) of pseudomonas aeruginosa in Zhongshan area to provide a basis for clinical anti-infection treatment .Methods Seventy-six clinically isolated strains of Pseudomonas aeruginosa were collected from the Zhongshan Municipal People′s Hospital from July to September 2016 .Four virulence genes exoU ,exoS ,exoT and exoY were isolated from the strains by PCR .The Vitek2 Compact au-tomatic microbiological identification instrument was used to detect the sensitivity of antibacterial drugs .The enumeration data were processed with chi-square test .Results The detection rates of gene exoS and exoY were highest ,which were 52 .6% (40/76) and 63 .2% (48/76) respectively ;genotype exoU(-)exoS(+ )exoT (-)exoY(+ ) were predominant and accounted for 59 .26% .The positive rates of 4 virulence genes had no statistical difference between the multiple resistant and non-multiple resistant strains of pseudomonas aeruginosa .The resistance rates in the TTSS positive group to 13 kinds of drugs were commonly lower than those in the TTSS negative group ,the difference was statistically significant .Conclusion The geographic difference exists in virulence genes carrier of pseudomonas aeruginosa .The virulence genes carrying situation in both the multiple resistant and non-multiple resistant strains of pseudomonas aeruginosa is similar .
