Introduction
Myiasis refers to infestation of humans and/or animals by dipterous larvae [1]. Overall, more than 100 species of dipteran flies are present to cause Myiasis.[2] Myiasis wound mostly occurs when fly larvae infest open wounds. Major predisposing factors of this kind of myasis are poor socioeconomic conditions, extremes of age and negligence[3]. Myiasis is a well-known condition to veterinarians from underdeveloped regions and causes severe economic losses globally [4]. The prevalence of myiasis are reported both in human and animals mostly in rural, tropical and subtropical regions but now commonly seen in temperate zone also [5,6].
As with any sort of infestation of parasites, myiasis causes concerns for the possibility of secondary bacterial infection, since certain species of fly and their larvae harbor associated bacteria [7]. Of particular concern in our case, methicillin resistantstaphylococcus aureus (MRSA) is a gram-positive round shaped, anaerobic bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is usually a bacterium of both human and animals and often described as community associated, healthcare associated or livestock associated. Around 10% of the sporadic infections are due to livestock-associated MRSA [8]. The MRSA is only susceptible to Vancomycin but it has a carcinogenic effect. Therefore, we report a case of methicillin resistantstaphylococcus aureus isolated from a calf with myiasis wound in Bangladesh, as this is of global concern.
