Staphylococcus spp. Na cavidade bucal e na bolsa periodontal de indivíduos com periodontite crônica: presença e sensibilidade aos antibióticos

Staphylococcus are not usually studied in the oral cavity, when this happens, they are considered to belong to transitory microflora. Individuals that present periodontal disease represent possibles reservoirs of these opportunist bacteria in the oral cavity. The use of antibiotics whether for treatment of periodontal disease or due to hospital infections, may predispose the increase of the Staphylococcus spp. in the oral cavity because they easily become resistant to antibiotics, resulting in superinfection. The study was made with 88 patients, minimum age- 25 years old, presenting chronical periodontitis, with, at least, two sites having a probing pocket bigger or equal to 5mm. After anamnese and clinical periodontal examination samples were taken from the periodontal pocket using paper cones and from the oral cavity using mouth rinse. Of the total patients 37,50% presented Staphylococcus spp. in the periodontal pocket and 61,36% in lhe oral cavity; 27,27% presented bacteria in the two sites, not necessarily of the same specie. S. epidermidis was the most prevailing specie in periodontal pocket (15,9%) and oral cavity (27,27%). Positive for S. aureus in the periodontal pocket were 4,5% and for the oral cavity 25%, and 3,4% were positive for the two sites. There was not found significative statistical difference referring to the presence of the microorganisms as to age, smoking habit and increase of the probing depth. The majority of the isolated Staphylococcus samples showed resistance to the tested antibiotics, indicating that the drugs as an adjunct to periodontal therapy, must be seen with caution

Evaluation of fecal microorganisms of children with cleft palate before and after palatoplasty

This study isolated and quantified intestinal bacteria of children with cleft palate before and after palatoplasty. A prospective study was conducted from May 2007 to September 2008 on 18 children with cleft palate, aged one to four years, of both genders, attending a tertiary cleft center in Brazil for palatoplasty, to analyze the effect of surgical palate repair on the concentration of anaerobes Bacteroides sp, Bifidobacterium sp and microaerophiles Lactobacillus sp in feces of infants with cleft palate before and 24 hours after treatment with cefazolin for palatoplasty. There was significant reduction of Lactobacillus sp (p < 0.002), Bacteroides sp (p < 0.001) and Bifidobacterium sp (p = 0.021) after palatoplasty, revealing that surgery and utilization of cefazolin significantly influenced the fecal microbiota comparing collections before and after surgery. However, due to study limitations, it was not possible to conclude that other isolated factors, such as surgical stress, anesthetics and other medications used in palatoplasty might have a significant influence on the microbiota. Considering the important participation of the intestinal microbiota on both local and systemic metabolic and immunological activities of the host, professionals should be attentive to the possible influence of these changes in patients submitted to cleft repair.

A comparison of microbiological and molecular detection of vaginal Lactobacillus spp. between mares and women

A possible explanation for endometritis in mares is ascendant contamination from the vagina. The presence of Lactobacillus spp. is considered to be important in women for a healthy vaginal environment; however, there are few studies in mares related to the presence of Lactobacillus in the vaginal flora of healthy mares. The present work aims to determine the occurrence of Lactobacillus spp. in the vaginal micro-environment of mares. A total of 35 crossbred multiparous mares, aged between 4 and 12 years, with no history of reproductive problems and with healthy reproductive tracts, were used. Two vaginal swabs were obtained from the mares during estrus for Lactobacillus isolation and PCR evaluation. Ten human female volunteers, aged between 24 and 35 years, sexually active, with no history of gynecological diseases and treatments in the past two years were used. Lactobacillus spp. were isolated from 5.7% of the mares' vaginal samples and from 90% of the women's vaginal samples. Lactobacillus DNA was detected by PCR in 22.9% of the mares' vaginal samples and in all of the vaginal samples from the healthy women. The primers used here were demonstrated to have in silico specificity for the detection of L. equi (AB425924.1), L. pantheris (DQ471798.1) and L. mucosae (DQ471799.1), but they did not anneal on Enterococcus faecalis (EU887827.1) or E. faecium (EU887814.1). In conclusion, this study showed a low occurrence of Lactobacillus spp. in mares, suggesting that this bacterium may not play a fundamental role in the equilibrium of the vaginal micro- environment of normal mares.
