Fig. 4. Virulence of strains by mouse infection. Following in vitro manipulation, strains were assessed for viralence by intraperitoneal injection of mice and subsequent microscopic detection of Giemsa-stained spirochetes in blood. Injection of equal numbers of (A) electrocompetent Borrelia hermsii DAH 2E7, (B) electroporated without a manipulation constmct or antibiotics and cloned by limiting dilution, and (C) the vtp mutant all produced comparable spirochetemias at 65 h post infection. Images of infected blood were taken at 400x.

HIV infection Imaging was used in an open study for 10 weeks in 15 subjects with human immunodeficiency virus (HIV) and evidence of cognitive decline there was no evidence of improvement in either cognition or mood [3 ].

Imaging studies also may help to identify anatomic localization of the infection. These studies usually are performed in conjunction with other tests to establish or rule out the presence of an infection. X-rays are performed commonly to establish the diagnosis of pneumonia, as well as the severity of disease (single versus multilobe involvement). CT scans are a type of x-ray that produces a three-dimensional image of the combination of soft tissue, bone, and blood vessels. In contrast, MRI use electromagnetic radio waves to produce two- or three-dimensional images of soft tissue and blood vessels with...

An interesting imaging probe Id that can selectively target bacteria was recently reported by Smith et al. [31] also based on a heptamethine chromophore. The probe is composed of a bacterial affinity group, which is a synthetic zinc (II) coordination complex that targets the anionic surfaces of bacterial cells and a near infrared dye. The probe allowed detection of Staphylococcus aureus in a mouse leg infection model using whole animal near-infrared fluorescence imaging. 

Gallium is non-essential, but on account of the similarity between Ga3+ and Fe3+ it binds to iron transport and storage proteins such as transferrin and ferritin. The radioactive isotope of gallium, 67Ga, concentrates to a large extent in many tumours and at sites of inflammation and infection, and since many tumours overexpress the transferrin receptor it can be used for tumour imaging.

The same liposomal preparation was used to investigate the effect of the administered dose on the biodistribution and pharmacokinetics (41). The effect of the lipid dose of Tc-HYNIC-PEG-liposomes was investigated in the low-dose range (0.02-1.0 pmol/kg), typically for noninvasive imaging applications. The biodistribution and pharmacokinetics of "Tc-HYNIC-PEG-liposomes at various dose levels were studied in rats and rabbits with a focal Escherichia coli infection. Moreover, the pharmacokinetics of Tc-HYNIC-PEG-liposomes at two lipid dose levels were studied in four patients. In rabbits, enhanced clearance was observed at a dose level of 0.02 pmol/kg. The circulatory half-life decreased from 10.4 to 3.5 hours (at 1.0 and 0.02 pmol/kg, respectively). At the lowest dose level, liposomes were mainly taken up by the liver and to a lesser extent by the spleen. Most importantly, the rapid clearance of low-dose PEG liposomes was also observed in humans when relatively low lipid doses were administered as is shown in Figure 4. This study showed that, at very low lipid doses, the biodistribution of PEG liposomes is dramatically altered.
