ABSTRACT.- Fluorescent Pseudomonas have been extensively reported as effective biocontrol agents and can be used to manage Pythium seedling diseases in alfalfa. An in vivo methodology was developed to evaluate fluorescent Pseudomonas isolates for their ability to suppress disease and promote plant growth in the alfalfa-Pythium pathosystem. The standard method consists of a bioassay performed in growth chamber under controlled conditions of temperature and photoperiod. Alfalfa seeds were sown in commercial substrate and subsequently treated as follows: no Pseudomonas, no Pythium debaryanum (germination control); inoculated only with P. debaryanum (disease control); each one of the Pseudomonas isolates co-inoculated with P. debaryanum. An augmented experiment design was obtained by selecting a random complete blocks design for four checks systematically evaluated on 12 bioassays, and enlarging the blocks to accommodate up to 16 treatments per assay. Disease control recorded an emergence of 33.2% on day 15 after sowing date, as compared with germination control (100%). The 101 fluorescent Pseudomonas isolates showed a wide response on disease suppression ability. Twelve percent of tested isolates reasonably protected alfalfa plants against P. debaryanum, recording an emergence of over 60%. A similar procedure, in the absence of the pathogen, was used to evaluate alfalfa growth-promoting ability of selected Pseudomonas isolates. Five isolates exhibited a significant biocontrol activity against P. debaryanum and four of them also recorded a significant plant growth-promoting effect. Both bioassays were appropriate to identify candidate Pseudomonas isolates to be further tested under field conditions.

Abstract:
Bovine parasitic sadness, comprised of the diseases babesiosis and anaplasmosis, has a large impact on cattle farming in several countries, as it compromises animal productivity. Using systematic review (SR)-meta-analysis (MA) methodology, our objective was to summarize and to investigate study characteristics associated with prevalence of Babesia spp. and Anaplasma marginale infection in Latin American cattle herds. Five electronic databases were used. The inclusion criteria were studies that assessed the prevalence of Babesia spp. and A. marginale in cattle in Brazil, Argentina, Uruguay, Paraguay, Colombia, and Mexico. The reported prevalences were converted to logistic scale and summarized using random effects MA. The heterogeneity was assessed, separately, for papers from Brazil and from the remaining countries. A total of 28 papers were included in this MA with a high heterogeneity (I2 > 95%). The prevalences of A. marginale, Babesia spp., and their co-infections, in Latin America, were 48.9% (95% CI: 30.3?67.8%), 39.8% (95% CI: 24.6?57.2%), and 26.1% (95% CI: 9.1?55.8%), respectively. The prevalence of A. marginale was higher due to the high prevalence of this agent in Mexico (67.1%). In Brazil, the prevalence was 36.6% for A. marginale, 62.6% for Babesia spp., and 8.2% for their co-infections. The North region of Brazil was reported with the highest prevalence for A. marginale (71.9%), while for Babesia spp., the prevalence was considerably divergent between regions, with the highest values also observed in the North region (97.4%), and the lowest in the South region (9.5%). For studies of Babesia spp. in cattle in Latin America, the heterogeneity was mainly explained by the diagnostic method (98.0%), and country (54.8%). When looking at Brazil alone, a similar pattern was observed, but with lower values (i.e., diagnostic method, 31.5%; region, 25.3%; and climate, 12,4%). The evaluated regions presented different levels of prevalence infections, with most of them being classified as high degree of enzootic instability, which can predispose to the occurrence of outbreaks.
