At a series of meetings, involving 27 clinicians from 11 countries, case definitions for the diagnosis of Lyme borreliosis in Europe were agreed and are presented here, with appropriate serological criteria, as a diagnostic guide. In a separate study questionnaires directed to clinicians were used to collect information on clinical aspects and risk factors of Lyme borreliosis. ⋯ Cardiac problems were rare. Tick bite was strongly associated with Lyme borreliosis, but the only other significantly associated risk factor was the pastime of gardening.

Liposomal amikacin for treatment of M. avium infections in clinically relevant experimental settings.
In an effort to optimize rational chemotherapy against M. avium infections in a clinically meaningful context, we tested whether liposome-encapsulated amikacin would effectively reduce the bacterial load in (i) intravenously infected immunodeficient SCID mice, (ii) immunocompetent mice in both early and late stages of intravenous infection, and (iii) immunocompetent mice with pulmonary M. avium infection. Although complete eradication of M. avium was never achieved following intravenous infection, mycobacterial CFUs decreased by 3 to 4 logs in the spleens and livers of mice treated for three weeks with twice-weekly intravenous injections of liposomal amikacin and continued to stay low in the liver, even in the absence of specific immunity. ⋯ Even moribund mice responded to liposomal amikacin by significantly gaining weight and survived their infected untreated littermates by at least 4 months. In contrast, during pulmonary M. avium infection, treatment with liposome-encapsulated amikacin only resulted in a transient plateau of bacterial proliferation in the lungs, and the infection exacerbated immediately after cessation of therapy.

Phage susceptibility, enterotoxigenicity and antibiograms of Staphylococcus aureus strains isolated from human wounds and diarrhoea.
The phage types, enterotoxigenicity and antibiograms of Staphylococcus aureus strains isolated from human diarrhoea and skin wounds in Nigeria were determined. Of 194 strains tested, 140 (72.2%) were typable using a combination of phages in the International Phage Set (IPS) for human strains of S. aureus and the bovine phage set. IPS phages lysed 118 (60.8%) strains while 96 (49.5%) were susceptible to bovine phages. ⋯ Occurrence of resistance to one or more antibiotics was higher amongst wound strains (97.5%) than amongst strains isolated from diarrhoea (52.6%). It was concluded that bovine phage 119 may be a useful epidemiologic marker for S. aureus strains of bovine origin associated with human diarrhoea in Nigeria. It is however difficult to ascribe any aetiological significance to these strains because other enteropathogens not assayed for may have been present.
