Serratia marcescens can be a plant growth promoting bacteria (PGPB) and an opportunistic human and plant pathogen. We have identified and characterized strains of related species of Serratia and evaluated their biological control of damping-off of tomato seeds caused by Pythium cryptoirregulare. Serratia ureilytica, S. bockelmannii and S. nevei were identified by phylogenetic analysis of partial gyrB gene sequence and average nucleotide identity (ANI). Tomato seeds inoculated with S. ureilytica ILBB 145 showed higher germination percentage and reduced damping-off in greenhouse experiment resembling a commercial operation, and volatiles produced by this strain caused the nearly complete inhibition in vitro of P. cryptoirregulare. Analysis of volatile organic compounds (VOCs) showed that ILBB 145 produced dimethyl disulfide (DMDS), which can partially account for this inhibition. Serratia bockelmannii ILBB 162 performance against damping-off was intermediate and the inhibition of P. cryptoirregulare in vitro was lower and explained by volatile and diffusible metabolites. Both strains augmented DMDS production in the presence of P. cryptoirregulare, suggesting this compound may play a role in the context of interspecific competition. Serratia nevei ILBB 219 showed the lowest inhibition of P. cryptoirregulare in vitro, no DMDS production, and no biocontrol in planta. Draft genomes of the three strains were annotated and individual genes and biosynthesis gene clusters were identified in relation with the observed phenotypes. We report S. ureilytica ? a low risk species- with activity as a biological control agent and DMDS produced by this bacterial species putatively involved in seed and seedling protection against P. cryptoirregulare.

Abstract: In Uruguay, control of Rhipicephalus microplus began in 1910. In 1941 the eradication of R. micoplus throughout the country was declared mandatory, although this attempt was unsuccessful. Since 2008 the country was divided into two regions: the south-western region, which is free of ticks; and a region of tick control that includes all departments to the north of the Rio Negro and five departments in the eastern region. In Uruguay, investigations on R. microplus, babesiosis and anaplasmosis started in 1921, and in the 1970s, studies of the epidemiology of R. microplus determined that from 2 to 3.5 generations can be produced annually and that the country is in an area of enzootic instability for babesiosis and anaplasmosis. Knowledge of tick epidemiology and of tick resistance to different acaricides led to the development of efficient methods of control or eradication, including integrated control and generational treatment. Although research results have led to a legal framework regarding R. microplus control, these measures have had variable results. This can be attributed to several factors, such as the discontinuation of the control measures,
variable financial resources, changes in the dynamics of livestock movement, failure to adopt available technology for tick control by farmers, climate change, environmental alterations such as forestation and the increasing resistance of ticks to acaricides, which led to the development of multiresistant ticks. This paper reviews the history of R. microplus, babesiosis and anaplasmosis in Uruguay and proposes alternatives for their control.
