Serratia spp., strain BRM 32114, is a plant growth-promoting rhizobacteria that show strong potential to solve two major challenges of upland rice production in a no-tillage system: initial vigor and grain yield improvement. No-till practices dictate the sustainability of cropping systems as they improve precipitation use, sequester C, mitigate atmospheric CO2 enrichment, restore soil health, and stimulate interest in crop diversity and rotation design. This study was intended to analyze the effect of the Serratia spp. on growth promotion and grain yield improvement in upland rice, under four N rates. Two field experiments were conducted during growing seasons 2015/2016 and 2016/2017, in two different experimental areas managed under a no-tillage system in the Brazilian Cerrado soil. The experimental design was a complete randomized block in a 4 × 2 factorial scheme, with four replications. Treatments comprised of four N fertilizer rates (0, 40, 80 and 120 kg N ha-1) with or without BRM 32114. In BRM 32114 treatment, rice seeds were microbiolized and bacterial suspension were sprayed at soil/plant in the field on the 7th and 15th DAS (day after sowing). Morphophysiological (gas exchange, shoot nutrients content and biomass production), and agronomic (grain yield and its components) traits were estimated. Results revealed increase in stomatal conductance (~ 20%); N, Ca and Mg (7, 11 and 9%) contents; shoot dry matter (8%); number of grain per plant (17%); mass of 1000 grains (2%) and yield (~ 22%) in BRM 32114-treated rice and cultivated in soil fertilized with 0, 40 and 80 kg N ha-1. However, the efficacy of this strain was reduced when combined with the highest rate of N (120 kg ha-1) added to the soil. It is possible to get higher yields levels of upland rice, cultivated under no tillage system, with the complimentary use of Serratia sp., strain BRM 32114, than the application of chemical fertilizers alone. The improvement in soil health could be extra benefit for fertilizer' savings.

Hepatozoon parasites comprise intracellular apicomplexan parasites transmitted to vertebrate animals by ingestion of arthropods definitive hosts. The present work aimed to investigate the occurrence of Hepatozoon spp. in wild animals, domestic dogs and their respective ectoparasites, in southern Pantanal region, central-western Brazil, by molecular techniques. Between August 2013 and March 2015, 31 coatis (Nasua nasua), 78 crab-eating foxes (Cerdocyon thous), seven ocelots (Leopardus pardalis), 42 dogs (Canis lupus familiaris), 110 wild rodents (77 Thichomys fosteri, 25 Oecomys mamorae, and 8 Clyomys laticeps), 30 marsupials (14 Thylamys macrurus, 11 Gracilinanus agilis, 4 Monodelphis domestica and 1 Didelphis albiventris), and 1582 ticks and 80 fleas collected from the sampled animals were investigated. DNA samples were submitted to PCR assays for Hepatozoon spp. targeting 18S rRNA gene. Purified amplicons were directly sequenced and submitted to phylogenetic analysis. A high prevalence of Hepatozoon among carnivores (C. thous [91.02%], dogs [45.23%], N. nasua [41.9%] and L. pardalis [71.4%]) was found. However, ticks and fleas were negative to Hepatozoon PCR assays. By phylogenetic analysis based on 18S rRNA sequences, Hepatozoon sequences amplified from crab-eating foxes, dogs, coatis and ocelots clustered with sequences of H. canis, H. americanum and H. felis. The closely related positioning of Hepatozoon sequences amplified from wild rodents and T. macrurus marsupial to Hepatozoon from reptiles and amphibians suggest a possible transmission of those Hepatozoon species between hosts by ectoparasites or by predation. Hepatozoon haplotypes found circulating in wild rodents seem to present a higher degree of polymorphism when compared to those found in other groups of animals. Although rodents seem not to participate as source of Hepatozoon infection to wild carnivores and domestic dogs, they may play an important role in the transmission of Hepatozoon to reptiles and amphibians in Pantanal biome.
