Cotton leafroll dwarf virus (CLRDV) has recently been discovered in the southern United States. The virus is transmitted by the cotton aphid and causes numerous symptoms including foliar chlorosis, distortion, leaf cupping, and reddened leaf veins. These symptoms were observed in a field in northeast Louisiana during the summer of 2019 approximately 2 weeks after cotton aphid infestation. Grafting infected cotton plants with healthy ones resulted in similar symptom development, and molecular diagnosis initially indicated and then confirmed the presence of CLRDV in sampled and grafted specimens, respectively. This the first report of CLRDV in Louisiana.

Although uncommon, Brucella infection can occur outside the areas of high endemicity, such as the USA. In the southern USA, hunters of wild swine are at risk for brucellosis. We present a case of a patient with fever, headache and constitutional symptoms that were ongoing for 11 months. He was diagnosed with neurobrucellosis. The patient was treated successfully with intravenous ceftriaxone, oral doxycycline and oral rifampin therapy. He had persistent neurological sequelae after completing treatment. This case illustrates the high index of suspicion needed to diagnose neurobrucellosis in a non-endemic country because initial symptoms can be subtle. The disease can be treated successfully, but long-lasting neurological sequelae are common.
