  In the present study, the in vitro inhibitory effects of G. glabra extract against the growth of Salmonella typhi, S. paratyphi B, Shigella sonnei, S. flexneri and enterotoxigenic E. coli (ETEC E. coli) was investigated using well and disc diffusion method. Shigella spp. and enterotoxigenic E. coli but Salmonella paratyphiB showed no susceptibility to liquorice with concentrations lower than 7.5%, however all tested bacterial strains exhibited susceptibility to high concentration of liquorice. Results obtained from present study showed that G. glabra can be considered as an alternative herbal antibacterial agent against the bacterial strains tested.

  In this study, directly observed short course therapy (DOTS) was implemented to control tuberculosis in a camp in Iran. First, one study had been conducted in 1996 (before DOTS implementation) as active case finding then DOTS have been implemented in 1997. Another study was carried out in 2004 for evaluation of the effects of DOTS. In the first study, 16 patients with pulmonary TB (50% smear positive) were detected. During the years of DOTS implementation, the number of TB cases decreased significantly. In the second study, no pulmonary TB was detected. Our experience showed that DOTS significantly and effectively decreases TB in refugees and leads to a high cure rate and prevents death.

  Incidence of asymptomatic bacteriuria during pregnancy among Iranian women was examined. Midstream urine was collected from 380 pregnant women and streaked on blood agar and incubated for 24 to 48 h. Growth was considered significant if 105 mL-1 bacteria were present. Among the pregnant women, 10.1% had asymptomatic bacteriuria. Age, past history of abortion, proteinuria, level of education, number of fertility had no significant association with asymptomatic bacteriuria occurrence. But lower socioeconomic status, leucocytosis and a history of UTI were associated with an increased incidence of asymptomatic bacteriuria (p<0.05). The most frequently isolated pathogen was Escherichia coli (68.4%), followed by Staphylococcus epidermidis (10.5%)) and Klebsiella pneumonia (8.3%). According to the results, co-trimoxazole was the best antibiotic; followed by nitrofurantoin which 60.5 and 44.7% of strains were sensitive to these two antibiotics, respectively.

  The present study was conducted to determine the prevalence of serotypes and antibiotic resistance in Shigella spp. isolated from patients admitted to Bouali hospital, Tehran, Iran during 1999 to 2001. All cases of shigellosis that were diagnosed according to their clinical pictures and microbial cultures were included in current study. Patients' age ranged from 12 to 89 years. Overall, 52 patients (56%) and 41(44%) were males and female, respectively. From a total of 90 Shigella isolates, 40 strains were identified as S. sonnei (45%), 26 as S. flexneri (27.9%), 3 as S. boydii (3%) and 21 as S. dysenteriae (24%). More than 95% of the isolates were susceptible to ciprofloxacin, ceftriaxone and ceftizoxim, 70% to nalidixic acid and less than 50% to co-trimoxazole, tetracycline, ampicillin and fourazolodon.

  Congenital palatal defects are common in animals but there is only one report of water buffalo has been recorded in Iran. One died male water buffalo calf was examined after hysterotomy operation. At necropsy findings, brachygnathia, palate cleft and small lungs were diagnosed. It is the second report of water buffalo cleft palate in Iran.

  The main objective of this study was to evaluate the prevalence of secondary bacterial infections in the patients with cutaneous lesions. The patients admitted to leishmaniasis laboratory of faculty of health, Tehran university of medical sciences from October 2004 to June 2005 were subjected in this study. Clinical samples were analyzed using standard bacteriological and parasitological methods. One hundred seventy three patients were subjected to this study and leishmania was found in 84 (48.5%) cases. According to bacteriological experiments, 47 cases (55.9%) had been also infected by bacterial infections. The most prevalent bacterial isolates included group D Streptococcus (19.1%), Enterococcus spp. (19.1%) and Staphylococcus aureus (12.7%). The findings of current study indicated that the bacterial infections are still an important problem in the patients with cutaneous leishmaniasis and should be considered in treating these patients.
