Adult mice are more resistant than neonatal mice to intestinal colonization with the protozoan parasite Cryptosporidium parvum. Development of a mature intestinal flora may play a role in this resistance. We compared susceptibilities to colonization with C. parvum in adult conventional mice, adult germfree mice, and adult conventional mice treated with oral antibiotics to deplete the intestinal...

Contrary to what used to be the case, actinomycosis is now a rare disease and only infrequently mentioned in otolaryngological textbooks (Ballantyne, J. and Groves, J. 1979). The disease is a chronic suppurative infection caused by micro-organisms from the actinomyces group, most often israelii. Actinomyces species are all oral commensals. They are gram-positive, non acid-fast, anaerobic or mic...

In the article the possibilities of new methods of diagnosis of periodontal diseases in teenagers are characterized. A hygienic condition of the oral cavity was evaluated by the use of the intraoral camera Durr Dental’s Vista Proof (Germany). The polymerase chain reaction (PCR) was performed to detect DNA of pathogenic periodontal bacteria in dental plaque. It was found that the increase in the...

Intestinal members of the family Enterobacteriaceae were eliminated in five human volunteers treated with oral ofloxacin for 5 days. No emergence of resistant Enterobacteriaceae was observed. Counts of group D streptococci were significantly reduced. Colonization by Candida sp. was observed in all five volunteers during ofloxacin treatment. The anaerobic flora was fairly stable from one sample ...

Actinomycosis is a rare, chronic, suppurative, granulomatous infection caused by a group of gram-positive anaerobic bacteria belonging to the natural flora of the oral cavity and gastrointestinal and urogenital tracts. It may involve several organs. This case study refers to pulmonary actinomycosis with chest wall involvement and cord compression in a 29-year-old male who presented with fever, ...

Candida is a common cause of oral mucous membrane and skin infections in newborn infants. Disseminated candidiasis and Candidemia have become a frequent problem in neonatal intensive care unit [1]. Candida species are frequently encountered as part of the human commensal flora. Colonization by Candida spp. is the most impor tant risk factor for development of Candidemia and IFI in pre mature in...

rain abscess is rare in patients with cystic fibrosis (CF). .E)Previously described cases have occurred in adults o adolescents and were caused by bacteria that are part of the normal oral flora.'1We report the case of an 8-year-old girl with moderately severe CF who developed severe headaches with vomiting and was found to have a cerebellar abscess caused by the fungus Blastomyces dermatitidis.

Patients with uncomplicated gonorrhoea were treated with a single dose of either ampicillin 3 g orally or procaine penicillin 2.4 MIU by injection, both with probenecid 1 g orally. The proportion of faecal Escherichia coli resistant to ampicillin before and a week after treatment was assessed. Of 55 patients treated with ampicillin who initially possessed sensitive flora, 25 (45.5%) became colo...

A normal part of the oral flora, Kingella kingae has seldom been recognized as the cause of serious clinical infections. We report a case of documented septic arthritis caused by K. kingae in an otherwise healthy infant. We suggest that it may be more common than thought based on the general unfamiliarity with this organism and the fact that several dozen clinical isolates have been identified ...
