Antibiotic resistance

Levofloxacin (LEV) is the common quinolone antibiotic and a practical option in H. pylori eradication regimens. The LEV resistance can be acquired through variant sequences of a gyrA. This study investigated the correlation between gyrA genetic diversity and LEV resistance in H. pylori.

Salmonella can carry multiple antibiotic-resistant and metalresistant genes and transmit these genes among strains worldwide. This study examined seventy-five Salmonella isolates from small-scale chicken farms (chicken feces, bedding, feed, wild animals) in Vinh Long province for the presence and relation of antibiotic and metal-resistance genes in these strains.

A total of 319 nasal swab samples were collected to clarify the prevalence and antimicrobial susceptibility of E. coli in the respiratory tract of goats in Can Tho, Vietnam. It indicated that E. coli was detected at a relatively minor rate (8.46%), and their prevalence in male goats and dairy goats was higher than that in others.

The rate of antibiotic resistance in Helicobacter pylori (H.pylori) is increasing in Vietnam in recent years and has become a main challenge in the management of H. pylori infection. To determine the antibiogram of H.pylori strains isolated from a population in Central Vietnam to clarithromycin, levofloxacin by E-test and disk diffusion, compare two diffusion methods.

Group B streptococcus (GBS) infections are still the leading cause of invasive infections in neonates, specically they also seriously cause mortality and morbidity with underlying diseases in adults. Curently, there are ten GBS serotypes (Ia, Ib, and II-IX) and the resistance characteristic of GBS is important to clinical treatment.

According to statistical data of many countries in the wold, the more proportion of patients in hip replacement have, the more prosthetic infection have been treated. In Vietnam, treatment of prosthetic infection is often difficult beacause of antibiotic resistance, high cost treatment and difficult rehabilitation in post-surgery.

India accounts for 30% of neonatal deaths globally. Bacterial sepsis is a significant cause of morbidity and mortality in newborns. The study helps to make antibiotic policy in neonatal sepsis. The main objective is to study the incidence of multidrug resistant gram negative and gram positive organisms causing neonatal septicemia and their antibiotic sensitivity pattern. The study was conducted in the Department of Microbiology over a period of one year. Sample of blood was collected under aseptic precautions and processed by standard techniques.

Insect pests and pathogens (fungi, bacteria and viruses) are responsible for severe crop losses. Insects feed directly on the plant tissues, while the pathogens lead to damage or death of the plant. Plants have evolved a certain degree of resistance through the production of defence compounds, which may be aproteic, e.g. antibiotics, alkaloids, terpenes, cyanogenic glucosides or proteic, e.g. chitinases,b-1,3-glu-canases, lectins, arcelins, vicilins, systemins and enzyme inhibitors.

A novel cosmid (pABC6.5) whose DNA insert fromStrep-tomyces capreolus, the A201A antibiotic producer, overlaps the inserts of the previously reportedpCAR11 andpCAR13 cosmids, has been isolated. These two latter cosmids were known to contain the aminonucleoside antibiotic A201A resistance determinants ard2 and ard1, respectively. Together, these three cosmids have permitted the identifi-cation of a DNA stretch of 19 kbbetweenard1andard2, which should comprise a large region of a putative A201A biosynthetic (ata) gene cluster....

Tetracycline repressor (TetR), which constitutes the most commonmechanismof bacterial resistance to an antibiotic, is a homodimeric protein composed of two identical sub-units, each of which contains a domain possessing a helix– turn–helix motif and a domain responsible for binding tetra-cycline. Binding of tetracycline in the protein pocket is accompanied by conformational changes in TetR, which abolish the specific interaction between the protein and DNA.
