Equine piroplasmosis is a tick-borne disease caused by the intraeytrhocytic protozoans Babesia caballi and Theileria equi. It has been reported as a main equine parasitic disease. In addition, Anaplasma phagocytophilum, the causative agent of granulocytic ehrlichiosis, causes a seasonal disease in horses. Both diseases, can be detrimental to animal health. In this sense, blood samples and ticks were collected from 97 horses raised in the microregion of Baixada Maranhense, Maranhão State, Brazil. Serum samples were subjected to Indirect Fluorescence Antibody Test (IFAT) and blood samples and ticks to Polymerase Chain Reaction (PCR) to evaluate the infection by Theileria equi, Babesia caballi and Anaplasma phagocytophilum. The overall seroprevalence was 38.14%, 18.55% and 11.34% for T. equi, B. caballi and A. phagocytophilum, respectively. The results of PCR from blood samples showed 13.40% and 3.09% positive samples to T. equi and B. caballi, respectively. A total of 170 tick specimens were collected and identified as Dermacentor nitens, Amblyomma cajennense sensu lato and Rhipicephalus (Boophilus) microplus. It was detected 2.35% (4/170) and 0.59% (1/170) positive tick samples by PCR for T. equi and B. caballi, respectively. All samples were negative to A. phagocytophilum. No statically difference (p>0.05) was observed when gender, age, use of ectoparasiticide and tick presence were analyzed. A BLASTn analysis of the sequenced samples indicated 97 to 100% similarity with T. equi 18S rRNA gene sequences in GenBank and 98 to 100% with B. caballi. Genetic analysis classified the obtained sequences as T. equi and B. caballi cluster, respectively. It can be concluded that these pathogens occur and are circulating in the studied area.

This work presents a kinetic study of the enzymatic hydrolysis of three cellulosic substrates: filter paper (FP), used as a low recalcitrance substrate model; steam exploded sugarcane bagasse (SB); and weak acid pretreated SB (1:20 dry bagasse:H2SO4 solution 1% w/w), the last two delignified with 4% NaOH (w/w). The influence of substrate concentration was assessed in hydrolysis experiments in a shaker, using Accellerase® 1500, at pH 4.8, in 50 mM sodium citrate buffer. Cellulose loads (weightsubstrate/weighttotal) were changed between 0.5%-13% (for FP) and 0.99%-9.09% (for SB). For FP and low loads of steam exploded SB, it was possible to fit pseudo-homogeneous Michaelis-Menten models (with inhibition). For FP and higher loads of steam exploded SB, modified Michaelis-Menten models were fitted. Besides, it was observed that, after retuning of the model parameters, it is possible to apply a model fitted for one situation to a different case. Chrastil models were also fitted and they were the only feasible approach for the highly recalcitrant acid-treated SB. |
