Sammanfattning : Pine weevils cause major damage to newly planted conifer seedlings in reforestation areas. However, recent findings indicate that small (“mini”) seedlings, planted at the age of 7-10 weeks, are gnawed less by pine weevils than the larger, conventionally planted seedlings. LÄS MER
3. Urinary tract infection in small children: aspects of bacteriology, vesicoureteral reflux and renal damage
Sammanfattning : Background: Urinary tract infection (UTI) is a prevalent bacterial infection in children. The diagnosis is based on growth of bacteria in urine specimen and treatment is chosen out of knowledge of the present antimicrobial resistance situation. Vesicoureteral reflux (VUR) is a well-known risk factor for UTI in children. LÄS MER
