Published series (1982–2007) of more than 5 HIV-infected adult cases on radiological presentation of cerebral cryptococcosis.

a<p>CT: computed tomography.</p>b<p>MR: magnetic resonance image.</p

Neuroradiological analysis of 55 computed tomographies and 24 magnetic resonance images collected at baseline from 62 HIV-infected patients with culture-proven cryptococcal meningoencephalitis.

a<p>With evidence of subdural collection.</p>b<p>Some patients had more than one lesion.</p

Examples of abnormal radiological findings.

<p>A. Magnetic Resonance axial T2-weighted image, displaying bilateral dilated Virchow-Robin spaces (arrow) in the basal ganglia. B. Magnetic Resonance axial T2-weighted image displaying a hyperintense right occipital mass (arrow head) and bilateral dilated Virchow-Robin spaces (arrow). C. Magnetic Resonance axial T1-weighted image with contrast infusion displaying frontal subdural collection (arrow). D. Magnetic Resonance axial T1-weighted image with contrast infusion displaying a basal meningeal enhancement (arrow).</p

Intravital fluorescence micrograph showing several deposits of sporozoites in the mouse skin.

<p>A: Global view of mouse skin bitten by a mosquito infected with GFP-labeled sporozoites. Small arrows indicate sporozoite deposits; B and C: enlargement of two pools of sporozoites indicated by large arrows.</p

Role of <i>Plasmodium berghei</i> infection on probing and blood meal of <i>Anopheles gambiae</i> using the second protocol.

Intravital micrographs illustrating probing with salivation.

<p>Series of bubbles were observed at each movement of the proboscis (A to D), as shown by arrows.</p

Localization of saliva in the dermis of mice bitten by <i>Anopheles gambiae</i>.

<p>Saliva was detected with rabbit anti-saliva antibodies 30 minutes, 1 h, 3 h and 18 h after the bite. A: Giemsa staining, B: saliva staining. Magnification: ×20.</p

Photomicrographs of skin sections and underlying tissues of naive mice bitten by uninfected <i>Anopheles gambiae</i> mosquitoes.

<p>These observations were made on mice killed one hour after the bite. A, B, C: HE staining; D: Giemsa staining; B. The magnification was ×20 for A and B and ×40 for C and D.</p

Local tissue damage on the inner surface of the skin after <i>Plasmodium berghei</i>-infected mosquito bites.

<p>Infected mosquitoes were selected by the visualization of fluorescent sporozoites in the salivary glands of cold-anesthetized insects under a fluorescence microscope. Mice were exposed to the bites of 50 infected mosquitoes for 15 minutes and killed at various time points: A) 1 h; B) 3 h; C) 16 h; D) 24 h; E) control. Thirty minutes before the mice were killed, they were injected with Evans Blue for the monitoring of capillary extravasation.</p
