Antibacterial antibodies for some enterobacteria in sera of patients with reactive arthritis and other rheumatoid diseases.

The presence of the specific antibodies for some enterobacteria--Yersinia, Salmonella and Shigella was investigated in patients hospitalized in the period 2000-2007 with reactive arthritis and other rheumatoid diseases. The antibacterial antibodies in the diagnosis titres were found in 172 out of 1102 (15.6%) patients.

Sensitivity of Enterobacteriaceae strains to the third generation cephalosporins.

The aim of this study was to evaluate the in vitro activity of cefotaxime, ceftriaxone, ceftazidime, ceftibuten and aztreonam against the clinical isolates of Enterobacteriaceae. MICROORGANISMS: A total of 973 enterobacteria isolated from clinical material (urine and faeces) were tested. Strains were collected during 1996-1998 period, in some centers of Eastern Romania.

The presence of some yeasts species in occupational dermatitis.

The samples of skin lesions were collected from forearms, palms and phalanges of ten females working in a manufacturing section (clothes tailoring and assemblage) using imported textiles. The samples were examined for bacteriological and mycotic flora by using classical methods. The textile fragments of 1-2 square centimeters from four samples were investigated using the same classical methods.

[Enterobacteriaceae isolated in eastern Romania: the evolution of ampicillin sensitivity in the 1970-1995 period].

The activity of ampicillin against 3383 Enterobacteriaceae (community and clinical isolates), collected in Eastern Romania, during 25 years was tested. Data were prelucrated by the box-plot method proposed by Simpson and Donnelly. The resistance degree for all species tested has progressively increased.

Development of resistance in Shigella flexneri isolates obtained in the past 20 years in eastern Romania.

Our study is focused on the antimicrobial activity for a number of 626 Shigella flexneri strains collected from epidemic outbreaks and hospitalised patients during 1976-1995 period, in Eastern Romania. The metodology used for determining the in vitro activity of the antimicrobials was that described by NCCLS. The agents which are currently used in therapy (ampicillin, tetracycline, chloramphenicol) are less active than the newer drugs (third generation cephalosporins, aztreonam, imipenem, ciprofloxacin) for which sensitivity ranged between 93-100% The associated resistance between ampicillin, tetracycline, chloramphenicol was demonstrated.

Detection of beta-lactamase production and enzyme profiles in Enterobacteriaceae isolated in Moldova.

In our study, out of 449 Enterobacteriaceae strains isolated between 1985 and 1990, 16 strains (3 Proteus, 6 nontyphoidal Salmonella, 7 Escherichia coli) were resistant both to Ampicillin- Sulbactam and Amoxycillin-Clavulanic acid associations. The activity profiles of the beta-lactamases produced by these resistant strains are described. Sarcina lutea ATCC 9341 was used as test strain.

Serological diagnosis in human Yersinia infections.

Serological examinations revealed Y. enterocolitica 0:3 specific antibodies in 34% of 80 children affected by a yersiniosis epidemic at titres of 1/40-1/640 and in all sporadic Yersinia enteritis cases. Similarly, agglutinins were identified for Y.

Studies of bacterial, rotaviral and Cryptosporidium etiology of acute diarrheal diseases in hospitalized children.

657 hospitalized children with acute diarrheal disease were studied for bacterial and rotaviral etiology. Cryptosporidium presence was followed in 123 children. Intestinal pathogens were detected in 195 (29.

Isolation of Yersinia group in human infections, animals and environment factors.

The presence of Y. enterocolitica and Y. pseudotuberculosis was studied in 4479 enteritis cases, 430 children, presenting appendicular syndrome, and 60 hospitalized patients with arthritis and Reiter syndrome.

[The presence of the Yersinia group in environmental factors, food and some animal species].

In a broad bacteriologic investigation, including more than 3,000 examination of domestic animals (porcines, bovines), fish, food (milk, ice cream), surface waters and soil, 27 strains of Yersinia enterocolitica were isolated. Of them 22 belonged to the O3(-8); O5(-6); O5,7,8(-2); O6(-2); O7(-2); O9(-2) serotypes, and 5 could not be serotyped, but were included in the biotype I. The strains isolated from fish, food and environment had a biochemical and/or serologic behaviour similar to that usually referred to man.

Presence of Yersinia specific antibodies in hospitalized patients with arthritis and Reiter syndrome.

A number of 50 patients admitted with arthritis and Reiter syndrome were investigated to detect the presence of Yersinia specific antibodies. The specific antibodies were evidenced in 5 patients (10%)--3 with antibodies to Y. enterocolitica and 2 with antibodies to Y.

[Presence of the rotavirus antigen in newborn infants at maternity hospitals in Moldavia].

Studies conducted on 417 feces samples collected from newborn infants from seven maternity homes revealed the presence of rotavirus in 1.2 to 9.5% of the subjects.

[Mixed viral-bacterial infections in infants with gastroenteritis].

Fecal specimens from 84 children with gastroenteritis were submitted to virological and bacteriological analysis. Enteroviruses other than poliovirus were found in 8.3%, rotavirus in 4.

[Detection of the rotavirus group antigen by a screening test using the ELISA-IC kit in subjects with acute gastroenteritis, at the pediatric services of Moldavia].
