In this article I will briefly describe meerkats and their social behaviours and then examine the possible mechanisms by which the cooperative raised guarding behaviour of the meerkats may have evolved.
Corneal diseases are one of the main causes of vision loss and blindness. Ocular morbidity in turn is mainly caused by Fungal Keratitis, throughout the world and especially in Asia. Isolation of the etiological agent and accurate diagnosis are important for the successful treatment of this disease. In extreme cases of infection the fungi penetrate the Descemet's membrane ultimately leading to tissue necrosis. Under such conditions, corneal transplantation is the most effective cure. The corneas that are excised are stored in Mc Carey Kaufmann (MK) media. The objective of this study was to analyze the epidemiological and microbiological features, pre disposing factors associated with Fungal Keratitis.
