Wild and domestic bird faeces likely source of psittacosis transmission-A case-control study in Sweden, 2014-2016.

Psittacosis is a zoonotic disease transmitted by birds. In Sweden, where psittacosis is notifiable, an average of eight cases per year were reported between 2002 and 2012. In 2013, an unusual increase in cases in southern Sweden was associated with exposure to wild birds.

Multiple human-to-human transmission from a severe case of psittacosis, Sweden, January-February 2013.

Proven transmission of Chlamydia psittaci between humans has been described on only one occasion previously. We describe an outbreak which occurred in Sweden in early 2013, where the epidemiological and serological investigation suggests that one patient, severely ill with psittacosis after exposure to wild bird droppings, transmitted the disease to ten others: Two family members, one hospital roommate and seven hospital caregivers. Three cases also provided respiratory samples that could be analysed by PCR.

Unusual increase of psittacosis in southern Sweden linked to wild bird exposure, January to April 2013.

Free-living wild birds worldwide act as reservoir for Chlamydia psittaci, but the risk of transmission to humans through contact with wild birds has not been widely documented. From 12 January to April 9 2013, a total of 25 cases of psittacosis were detected in southern Sweden, about a threefold increase compared with the mean of the previous 10 years. A matched case-control study investigating both domestic and wild bird exposure showed that cases were more likely than controls to have cleaned wild bird feeders or been exposed to wild bird droppings in other ways (OR: 10.

Little evidence for reversibility of trimethoprim resistance after a drastic reduction in trimethoprim use.

Objectives: The worldwide rapid increase in antibiotic-resistant bacteria has made efforts to prolong the lifespan of existing antibiotics very important. Antibiotic resistance often confers a fitness cost in the bacterium. Resistance may thus be reversible if antibiotic use is discontinued or reduced.

Diagnosis-prescribing surveys in 2000, 2002 and 2005 in Swedish general practice: consultations, diagnosis, diagnostics and treatment choices.

The aim of this study is to present diagnostic patterns, diagnostics used and antibiotic treatment in relation to guidelines in 3 repeated diagnosis-prescription studies conducted simultaneously in general practice in 5 Swedish counties, during 1 week in November 2000, 2002 and 2005. General practitioners (GPs) at the participating health centres were asked to complete a form for all patients with symptoms of an infectious disease. During the studied periods a total of 15,371 consultations was registered.

Upper respiratory tract infections in general practice: diagnosis, antibiotic prescribing, duration of symptoms and use of diagnostic tests.

A diagnosis/antibiotic prescribing study was performed in 5 counties in Sweden for 1 week in November 2000. As part of this study, the characteristics and clinical management of patients with upper respiratory tract infections (n = 2899) in primary care were analyzed. Almost half of the patients were aged < 15 y and one-fifth of the patients consulted out of hours.

Intrafamilial spread of highly virulent staphylococcus aureus strains carrying the gene for Panton-Valentine leukocidin.

Necrotizing pneumonia caused by Staphylococcus aureus carrying the gene for Panton-Valentine leukocidin is a newly described disease entity. We report 2 cases with intrafamilial spread.

A case of foodborne listeriosis in Sweden.

A 70-year-old woman fell seriously ill overnight with meningitis and was admitted to hospital. Cerebrospinal fluid culture yielded Listeria monocytogenes. One of the first problems in solving a human case of listeriosis suspected to be foodborne is to find the foods likely to have been transmitting L.

An epidemiologic study of Lyme disease in southern Sweden.

Background: Lyme disease is the most common vector-borne infection in some temperate regions of the Northern Hemisphere. However, for most areas of endemic disease reliable epidemiologic data are sparse.

Methods: Over a one-year period, we conducted a prospective, population-based survey of cases of Lyme disease in southern Sweden.

Retrospective analysis of the efficacy of cefotaxime sodium dosed twice daily. The Swedish experience.

In a Swedish multicenter, comparative, retrospective study, patients with different types of infections--bacteremia-septicemia, genitourinary, intra-abdominal, central nervous system, and lower respiratory tract infections--were randomly selected from the hospital records. Patients treated with cefotaxime twice or three times a day as monotherapy (excluding metronidazole) for at least 1 day (240 cases) were analyzed in terms of clinical and bacteriologic outcome, these results were correlated with the dosing regimen. Similarly high success rates (cure and improvement) at hospital discharge were observed in both group initially treated with cefotaxime 1 g twice daily and 2 g twice daily (97 and 96%, respectively).

Seven patients with relapses of Plasmodium vivax or P. ovale despite primaquine treatment.

Seven relapses of Plasmodium vivax or Plasmodium ovale despite standard treatment with primaquine (3.0 mg Kg-1) daily for fourteen days are presented. The majority of patients came from areas outside the countries where resistance to primaquine is well known.

Binding of fibrinogen degradation products to S. aureus and to beta-hemolytic streptococci group A, C and G.

Binding of fibrinogen degradation products was measured to Gram-positive cocci known to carry receptors for human fibrinogen. Forty-one strains of S. aureus and group A, C and G streptococci were studied.
