Lesions found in bat tissues stained with hematoxylin and eosin in study of histopathologic changes in Mops condylurus bats naturally infected with BOMV, Kenya*

Organ Lesion BOMV-infected† Uninfected†
Lung
 Mild perivascular and interstitial mononuclear infiltrates 3/3 4/6
Scattered thickening of pulmonary vessel walls 2/3 1/6
Mild peribronchial mononuclear infiltrates
 1/3
 2/6
Liver
 Mild perivascular mononuclear infiltrates 3/3 1/6
Moderate chronic neutrophilic infiltrates 0/3 3/6
Mild hepatocellular vacuolation
 0/3
 1/6
Heart
 Mild mononuclear infiltrates
 0/3
 2/6
Stomach Moderate chronic granulomatous gastritis with intralesional nematodes 0/3 2/6

*Comparisons were made between BOMV RT-PCR–positive (BOMV-infected) and RT-PCR–negative (uninfected) Mops condylurus bats. Lesions likely represent spontaneous background lesions, except for the neutrophilic infiltrates in liver tissue and granulomatous gastritis nematodiasis. BOMV, Bombali virus. †Number of bats with lesions/total number of bats per group (infected or uninfected).
