The objective of the present work was to study the efficiency and diversity of nitrogen-fixing bacteria that colonize the weed Macroptilium lathyroides (L.) Urb. M. lathyroides roots were collected in areas of natural infestation of the species in rural and periurban areas of the municipality of Alta Floresta-MT, Brazil. The roots that presented nodulation were washed and their nodules removed, disinfected and inoculated in culture medium 79 in Petri dishes. These were incubated in a germination chamber in the dark at 28°C for 10 days, after which time the colonies were purified by streaking. The authentication experiment was conducted in a greenhouse and showed that of the 39 isolates, 19 of them had potential to be conducted for the nitrogen fixation efficiency test. The sequencing of the 16S rDNA gene identified the following bacteria that colonize the roots of the species: Mucilaginibacter gossypiicola, Novosphingobium arabidopsis, Bacillus haynesii, Bacillus xiamenensis, Bradyrhizobium namibiense and Flavobacterium anhuiense. Isolates M004, M005 and M022 showed values of nitrogen content very close to the ?with N? treatment, being indicated for further studies with commercially important cultures. |

The objectives of this study were to: (1) evaluate the feasibility of ultrasonic biomicroscopy (UBM) for imaging ovarian follicles in vivo in cows and heifers, (2) compare the transvaginal to the transrectal approach, (3) compare the number of follicles detected by UBM to conventional ultrasonography (US), and (4) identify cumulus-oocyte-complexes (COC) within follicles by UBM. Mature cows (n = 5) and peri-pubertal heifers (n = 5) were examined once using conventional B-mode US (Aloka 900) with a 7.5 MHz transrectal, and a 5 MHz transvaginal transducers. A second series of examinations was performed using UBM (Visualsonics Vevo 660) equipped with a 30 MHz transrectal and a 40 MHz transvaginal transducer. A three- to four-fold increase in the number of small follicles (<3 mm) was detected using the transvaginal approach with UBM compared to conventional US in both heifers (32.4 ± 4.24 compared to 7.2 ± 1.4; P < 0.0001) and cows (35.0 ± 13.8 compared to 10.7 ± 7.5; P = 0.0013). However, fewer follicles (all sizes combined) were detected using the transrectal approach with UBM compared to conventional US in both heifers (8.6 ± 5.6 compared to 17.6 ± 4.9; P = 0.02) and cows (5.3 ± 6.1 compared to 20.3 ± 7; P = 0.04). In heifers, COC-like structures were identified in 39 of 202 (19.3%) follicles examined. In conclusion, UBM using a transvaginal approach is feasible and may be used for in vivo assessment of early antral follicles as small as 0.4 mm, and COC within follicles. |
