The study consisted of microbiological urinalysis performed in 269 patients after renal transplantation who remained under medical care at the Outpatient Service of the Transplantation Institute in Warsaw. The patients enrolled into the study had undergone renal transplantation 6 to 72 months before urine samples were collected. 304 urinalysis were performed. In the group of 269 patients, 42 individuals had bacteria in their urine what was confirmed in 47 urine cultures. Cases of bacteriuria were divided into 5 groups: 5 cases of symptomatic urinary tract infection (5 individuals - 2% of all studied patients), 27 cases of asymptomatic bacteriuria in 22 individuals (8% of all studied patients), 5 cases of insignificant bacteriuria in 5 patients (2%), 10 cases of involuntary urine contamination in 10 cases (4%). Eventually, urinary tract infection (UTI) was established in 27 patients (5 cases of symptomatic UTI and 22 cases of asymptomatic UTI) what makes out for 10% of all studied patients. In cases where urinalysis showed significant bacteriuria, following pathogens were detected in urine cultures: Escherichia coli: 22 strains, Enterococcus faecalis - 4 strains, Enterobacter cloacae - 2 strains and 1 strains of Ralstonia picketii, Streptococcus uberis, Pseudomonas aeruginosa and Proteus mirabilis. Over 90% of Gram-negative bacteria were susceptible to ceftriaxone and ceftazidime, as well as to amikacin and aztreonam which are the drugs usually administered intravenously in hospitalized patients. The only drug of similar efficacy, which could be administered orally in outpatients was fosfomycin.
Mycobacterioses are a constant problem in backyard poultry, as well as pet birds. To date, no evidence of direct transmission of atypical bacilli between humans has been demonstrated, but it cannot be ruled out that sick animals can be a source of infection for people in their environment. The aim of the study was to identify mycobacteria isolated from birds with diagnosed mycobacteriosis and to determine the susceptibility of mycobacterial isolates from these animals to antituberculous drugs most commonly used in the treatment of mycobacterial infections in humans. For drug susceptibility tests, drugs such as isoniazid, rifampicin, streptomycin, ethambutol, ofloxacin, capreomycin, cycloserine and ethionamide were used. A high degree of drug resistance was demonstrated, particularly in Mycobacterium avium. Isolates of Mycobacterium xenopi showed a relatively good susceptibility to the drugs tested. The drug resistance of Mycobacterium genavense has not been determined, but this mycobacterium was identified in ten cases, which is the second most frequent occurrence in the cases studied.
