PCR and nested-PCR methods were used to assess the frequency of Babesia bovis and Babesia bigemina infection in Boophilus microplus engorged females and eggs and in cattle reared in an area with endemic babesiosis. Blood and the engorged female ticks were from 27 naturally infested calves and 25 crossbred cows. The frequency of both Babesia species was similar in calves and cows (P>0.05). Babesia bovis was detected in 23 (85.2%) calves and in 25 (100%) cows and B. bigemina was detected in 25 (92.6%) calves and in 21 (84%) cows. Mixed infections with the both Babesia species were identified in 42 animals, 21 in each age category. Of female ticks engorged on calves, 34.9% were negative and single species infection with B. bigemina (56.2%) was significantly more frequent (P0.05) to the frequency of single B. bigemina infection (15.9%). Mixed Babesia infection was lower (PMenosPCR and nested-PCR methods were used to assess the frequency of Babesia bovis and Babesia bigemina infection in Boophilus microplus engorged females and eggs and in cattle reared in an area with endemic babesiosis.

Blood and the engorged female ticks were from 27 naturally infested calves and 25 crossbred cows. The frequency of both Babesia species was similar in calves and cows (P>0.05). Babesia bovis was detected in 23 (85.2%) calves and in 25 (100%) cows and B. bigemina was detected in 25 (92.6%) calves and in 21 (84%) cows. Mixed infections with the both Babesia species were identified in 42 animals, 21 in each age category. Of female ticks engorged on calves, 34.9% were negative and single species infection with B. bigemina (56.2%) was significantly more frequent (P<O.OI) than with B. bovis (4.7%). Most of the females (60.8%) engorged on cows did not show Babesia spp. infection and the frequency of single B. bovis infection (17.6%) was similar (P>0.05) to the frequency of single B. bigemina infection (15.9%). Mixed Babesia infection was lower (P<O.OI) than single species infection in female ticks engorged either in cows (5.7%) or in calves (4.3%). An egg sample from each female was analysed for the presence of Babesia species. Of the egg samples from female ticks infected with B. bovis, 26 (47.3%) were infected while from those from female ticks infected with B. bigemina 141 (76.6%) were infected (P<0.01). The results showed that although the frequency of both species of Babesia was similar in calves and cows, the infectivity of B. bigemina was higher to ticks fed on calves while to those ticks fed on cows the infectivity of both Babesia species was similar.

Com o objetivo de avaliar o efeito do cultivo continuo da cana-de-acucar em algumas propriedades quimicas de solos argilosos de tabuleiro, foram selecionados quatro talhes localizados na Usina Santa Clotilde, Municipio de Rio Largo, AL, a saber: um, coberto por vegetacao nativa (Tn), e os demais, cultivados por periodos de cinco (T5), quinze (T`5) e vinte e cinco (T25) anos. Os solos foram caracterizados morfologicamente, e nas amostras coletadas por horizonte foram determinados pH, C organico, P assimilavel, bases trocaveis, Al e H trocaveis, capacidade de troca de cations, saturacao por bases e saturacao por Al. Os resultados indicaram que, nas condicoes de solo e manejo das areas estudadas, o cultivo da cana-de-acucar proporcionou sensivel melhoria na fertilidade dos solos, contribuindo para a manutencao dos niveis de materia organica, aumentos no pH, Ca, Mg, P e saturacao por bases, e diminuicao da saturacoa por Al. A excecao do P, observou-se que grandes modificacoes se processaram em relacao ao solo virgem, e nao se verificaram variacoes logicas entre os perfis cultivados. |
