Nest defence against avian brood parasites is promoted by egg-removal events in a cowbird–host system

2011

Recent studies of birds have found that the antiparasite behaviour of host species is modified by social learning. We tested whether individual or social learning modifies the nest defence of yellow warblers, Setophaga petechia, against the parasitic brown-headed cowbird, Molothrus ater. Using field experiments, we exposed warblers to simulated events of nest parasitism and predation, or allowed them to observe conspecifics mobbing a cowbird. Intensity of nest defence by yellow warblers was greater after simulated threats at their nest than after they had observed mobbing of cowbirds by conspecifics. Warblers defended their nests more aggressively when they perceived a cowbird as an egg pre…

A severe case of Israeli spotted fever with pleural effusion in Italy

2021

Abstract Background The most common Italian rickettsiosis is Mediterranean Spotted Fever (MSF). MSF is commonly associated with a symptom triad consisting of fever, cutaneous rash, and inoculation eschar. The rash is usually maculopapular but, especially in severe presentations, may be petechial. Other typical findings are arthromyalgia and headache. Herein, we describe for the first time an unusual case of Israeli spotted fever (ISF) associated with interstitial pneumonia and pleural effusion in which R. conorii subsp. israelensis was identified by molecular methods in the blood, as well as in the pleural fluid. Case presentation A 72-year-old male presented with a 10-day history of remitt…

The stomach in liver cirrhosis

1991

Abstract The stomachs of cirrhotic patients are frequently subject to a number of alterations, detectable by endoscopy, the presence of which indicates a disturbance in the mucosa. Several investigators believe that portal hypertension plays an etiopathogenetic role. Three groups of subjects were studied prospectively: 83 cirrhotic patients with portal hypertension, 53 cirrhotic patients without portal hypertension, and 135 control subjects. Snake skin, scarlatina rash, and petechia were the most frequent endoscopic findings in the cirrhotic patients with portal hypertension ( P
