“…On the other hand, properties such as hydroxamate production or the presence of K1 antigen were found in microorganisms that persisted in the host without causing clinical symptoms. During the persistence in the urinary tract, uropathogenic E. coli also show marked changes in virulence, as shown by Ziegler et al [13]. In particular, the loss of haemolysin expression was significant (Fig.…”

“…Patients with the negative P1 antigen express a smaller amount of receptors for P fimbriated E. coli , so that attachment during passage through the boundary layer seems to be more difficult. It could be concluded that the existence of the P1 antigen may be a gap in the protective mechanism and could indicate an increased susceptibility to UTI 36. Women with a history of recurrent UTI are three to four times more frequently found to be nonsecretor phenotypes of the ABO histo-blood group than women without such a history 37.…”

Urinary tract infections (UTI) are common among the female population. It has been calculated that about one-third of adult women have experienced an episode of symptomatic cystitis at least once. It is also common for these episodes to recur. If predisposing factors are not identified and removed, UTI can lead to more serious consequences, in particular kidney damage and renal failure. The aim of this review was to analyze the factors more commonly correlated with UTI in women, and to see what possible solutions are currently used in general practice and specialized areas, as well as those still under investigation. A good understanding of the possible pathogenic factors contributing to the development of UTI and its recurrence will help the general practitioner to interview the patient, search for causes that would otherwise remain undiscovered, and to identify the correct therapeutic strategy.

Background: Blood group and its relation to bleeding time (BT) and clotting time (CT) is important in conditions like epistaxis, thrombosis, and surgery. Earlier studies depicted O group having prolonged BT and CT. The aim of this study was to assess the relationship of BT and CT with ABO groups.Methods: This cross-sectional study was conducted in the department of physiology, Gauhati medical college. The study included 154 students. Blood grouping was determined with the standard antiserum; BT and CT were estimated by the duke method and slide method, respectively. Blood group and its relation to BT, CT were analyzed by Chi-square analysis.Results: Blood group O (42.2%) was predominant in both genders followed by B (31.8%), A (21%), AB (4.5%). CT was found to be more than 6 minutes in group O (31.57%) followed by group AB (26.31%), A and B (21.05%). The difference was statistically significant (p = 0.02). BT was found to be more than 4 minutes in group O (82.35%) followed by A (11.76%), B (5.88%), and AB (0%). That was statistically significant (p = 0.01). CT was more than 6 minutes in 57.89% in females as compared to 42.10% in males, variation was statistically significant (p = 0.01). BT was more than 4 minutes in 58.82% females as compared to 41.17% in males. The variation was statistically significant (p = 0.03).Conclusions: In present study blood group O was more common followed by B, A, and AB. CT and BT were prolonged in O group. BT and CT were more in females than males.
