The CCR5Δ32 polymorphism is a 32-base pair deletion in the CCR5 gene that has been associated with slower HIV disease progression. However, its role in immune reconstitution during antiretroviral therapy (ART) remains unclear. We analyzed 236 virologically suppressed people living with HIV (PLHIV) after 24 months of ART, comprising 217 individuals homozygous for the wild-type CCR5 allele and 19 heterozygous carriers of CCR5Δ32...

Pathogenic fungi that cause rust adversely affect plants, including crops, affecting them differentially depending on the cultivar. This is the case of blackberry ( Rubus spp.), a member of Rosaceae, introduced in Brazil by Embrapa during the 1980s and 1990s. Given the advantageous nutritional properties of its fruits and the relatively low management costs associated with its cultivation, blackberry production has emerged as...

Bovine anaplasmosis is a tick-borne rickettsial disease of significant sanitary and economic importance to livestock, particularly in tropical and subtropical regions, and is associated with high morbidity and reduced productivity. However, data on its molecular prevalence in cattle from semiarid and transitional areas of the Northeast region of Brazil remain scarce. This study aimed to determine the prevalence of Anaplasma sp...

The pod fly Melanagromyza vignalis Spencer (Diptera: Agromyzidae) has posed a major constraint to cowpea cultivation because it damages pods and seeds, thus representing a pest of significant economic importance. This study aimed to clarify the identity of the pod fly responsible for damage to cowpea crops in the North and Northeast regions of Brazil. Specimens collected from cowpea production areas in the states of Pará, Para...
