The study of physical strength of 435 young men aged 18-19 preparing to join military service in Can Tho province. The year 2002 will all medical elements such as the height, chest measurement, the body weight and health conditions, showed that in comparing with 19 years old, the heigh, body weight and chest mean measurement of 18 years old men were similar. Health classification showed that in 18 years old men the grade 1st, 2nd and 3rd account for 74% and in 19 years old, 66% respectively. Stomatology and dental diseases got 9%, being the most common pathology

Aims: The objective of the study was to isolate bacteriophages and conduct a comprehensive analysis of their potential against Xanthomonas oryzae pv. oryzae (Xoo) strains in the Mekong Delta, Vietnam. Methodology and results: Twelve Xoo strains were isolated from rice fields located in the Mekong Delta, Vietnam. Among these strains, three strains Xoo L019, L020 and L024, showed the highest disease index of bacterial blight. Four phages specific to Xoo were isolated from soil, water and leaf samples, and their morphologies were determined. In a test against 12 Xoo strains, phage L541, MLA23 or W41 could infect 10 of the 12 Xoo strains, while phage LBH01 could infect 8 of the 12 Xoo strains. The stability of the phages to pH, organic solvents, UV-A and UV-B was also evaluated. Conclusion, significance and impact of study The initial characterization of the phages indicates their potential as biocontrol agents against bacterial blight in rice. The study is one of the very first studies about Xoo phages in rice in Vietnam.
