Susceptibilidade in vitro a antimicrobianos da Mannheimia haemolytica e da Pasteurella multocida isoladas de ovinos sadios e com doenças respiratórias

Pasteurella multocida and Mannheimia haemolytica (P. haemolytica) are associated with ovine respiratory diseases. With the purpose of observe the susceptibility in vitro of these organisms against antimicrobials, were collected samples of nasopharingeal (n=180) and oropharingeal (n=82) from ovines healthy and with respiratory disease. Among the antimicrobials tested, the sensibility was greater for enrofloxacin (100%) and florfenicol (100%), for both bacteria. The greater resistance indices for M. haemolytica and P. multocida were observed with tetracyclin (15.64% and 17.65% respectively) and penicillin (1.82% and 4.2%).

Doenças respiratórios em aves atendidas no Laboratório de Ornitopatologia da FMVZ-UNESP/Botucatu-SP, Brasil, nos anos de 2005 a 2006

The respiratory tract of birds shows anatomical and physiological characteristics that facilitates the occurrence of disease, mainly those of microbiological origin. This article analyzes the frequency of respiratory diseases in domestic and wild birds treated during the years 2005-2006 at the Ornitopathology Laboratory of the Veterinary Hospital, Faculty of Veterinary Medicine and Zootecnics, São Paulo State University (FMVZ-UNESP). Diagnoses were obtained through clinical and radiographic exams as well as haemogram, microbiological culture, parasitological tests and necropsy, being septicemic processes, aspergillosis and mycoplasmosis the most diagnosed diseases. No zoonotic threats were identified, so the entities were described as of low-impact on public health. However, the above mentioned agents can provoke death of birds and difficult for treating and eradication as well.

Influência de laminas de chuva no controle de plantas daninhas, semeadas em diferentes profundidades no solo, com aplicação de herbicidas pré-emergentes

The aim of this work was to evaluate the control in pre-emergence of the weeds brachiaria grass (Brachiaria decumbens) and goosegrass (Eleusine indica) in different depths in the ground, for the oxyfluorfen and isoxaflutole herbicides, applied in pre-emergence condition and submitted of different rain blades. The experimental design was entirely at random, with four repetitions. Each set was consisted of plastic vases with substratum capacity of 4L, filled with arenaceous ground, increased of brachiaria grass and goosegrass seeds in the depths: 0,5; 1,0; 3,0; 6,0 and 9,0 cm. Doses of 37,5 g a.i. ha -1 of isoxaflutole and 720 g a.i. ha -1 of oxyfluorfen were used. The rain blades was 5, 10 and 20 mm applied with a stationary rain simulator, beyond a treatment without rain. Visual evaluations of control at 7 and 14 days had been carried through after application of the herbicides, counting of germinated plants and dry biomass of plants without application. The development of both weeds was inhibited by herbicides, reaching 100% of control, in all depth levels. The different rain blades had not influenced the control of the weeds. In the biggest depth of sowing (9,0 cm), the emergence was above 45% to B. decumbens and 36% to E. indica in treatments without herbicides application.
