In this paper, we introduce a malaria model with an asymptomatic class in human population and exposed classes in both human and vector populations. The model assumes that asymptomatic individuals can get re-infected and move to the symptomatic class. In the case of an incomplete treatment, symptomatic individuals move to the asymptomatic class. If successfully treated, the symptomatic individu...

Intravesical instillation of Bacillus Calmette-Guérin (BCG) is used as an adjuvant treatment bladder cancer. Systemic BCG infection occurs in less than 1% cases, and pulmonary involvement even rarer (0.3% – 0.7%), with a favourable prognosis. A 78-year-old male developed miliary tuberculosis (TB) secondary to intravesical subsequent coronavirus disease 2019 (COVID-19) superinfection that led pa...

Lactobacilli are low-virulence, commensal organisms of the gastrointestinal and genitourinary tracts and are commonly used as "probiotic supplements." Herein, we describe an episode of respiratory syncytial virus (RSV) bronchiolitis with bacterial superinfection secondary to administration of Lactobacillus rhamnosus in an 11-month-old female with trisomy 21.

Fifteen pediatric patients with complicated urinary tract infections due to Pseudomonas spp. were treated for 10 to 18.5 days with ceftazidime administered intramuscularly twice daily. Urine sterilization during therapy was obtained in all patients. Three patients had relapses which were cured with a second course of ceftazidime. Minor liver damage, eosinophilia, and Candida superinfection deve...

Cytomegalovirus superinfection is associated with a poor prognosis in non-HIV Pneumocystis pneumonia (PCP) and can cause deterioration of PCP not only simultaneously but also after initiating PCP treatment. Cytomegalovirus pneumonia should be considered in cases with deterioration after initiating PCP treatment; multiple nodular lesions are useful findings for the diagnosis.

This paper reports an unusual pattern of serological HBV markers and the presence of HBsAg/anti-HBs immune complexes in serum samples from two patients with fulminant hepatitis from the Brazilian Western Amazon Basin. The diagnosis was made by both serologic tests and demonstration of antigen/antibody complexes by transmission electron microscopy. Concurrent Delta virus superinfection is also d...

OBJECTIVE Viral interference has been demonstrated in different systems, such as the effect of enterovirus infection on live-attenuated oral polio vaccine. In this study, the effect of reovirus which could exist in the human intestinal tract on poliovirus vaccine strains was investigated and could be an important factor to consider in oral polio vaccination. METHODS Cells were infected with r...

Patients were given aztreonam (SQ 26,776) parenterally for the treatment of various gram-negative infections. During or shortly after therapy, 8 (17.8%) of 45 patients became infected with or colonized by enterococcus. These eight cases included eight urinary tract isolates; one of these cases subsequently developed bacteremia. Five patients required further antimicrobial therapy directed again...
