Parasitological and serological diagnosis of Strongyloides stercoralis in domesticated dogs from southeastern Brazil

Canine strongyloidiasis is a parasitic infection caused by the nematode Strongyloides stercoralis and presents a great zoonotic potential. Its confirmation, using coproparasitological methods, is difficult. The detection of serum specific antibodies, however, may facilitate the diagnosis. The aims of this study were to determine the presence of S. stercoralis through the use of parasitological methods and to detect specific antibodies to the parasite in serum samples from domestic dogs by using the indirect fluorescent antibody test (IFAT) on slides and the enzyme-linked immunosorbent assay (ELISA). A total of 215 dogs of various breeds, from the cities of Uberlandia, Araxá and Campo Belo in the State of Minas Gerais, were examined and distributed according to age into the following groups: (I) 19 males and 20 females of 1-2 months old; (II) 11 males and 20 females of 2-month- to 1-year-old and (III) 41 males and 104 females, from 1 to 7 years old. Coproparasitological results showed that 63/215 (29.3%) of the dogs presented some kind of parasite, with two (0.9%) dogs (one from Araxá and the other from Uberlandia) passing S. stercoralis larvae in the feces. Serological results revealed antibodies to S. stercoralis in 45/215 (20.9%) of the dogs, with seropositivity rates of 0% (0/39) in Group I, 22.6% (7/31) in Group II, and 26.2% (38/145) in Group III. No serological cross-reactivity between S. stercoralis and hookworms or Ascaridae was found. Hookworm infections were seen in 31 dogs, but only one of these dogs (infected with both hookworm and Cystoisospora spp.) was S. stercoralis seropositive by IFAT. The present study demonstrated, for the first time, natural S. stercoralis infections in dogs diagnosed by coproparasitological and serological methods. It was concluded that the detection of specific antibodies to S. stercoralis by IFAT and ELISA may contribute to the diagnosis of canine strongyloidiasis.

海南肾茶病原根结线虫的鉴定及对其寄主生长的影响

了解海南肾茶根结线虫的种类、特征及其对肾茶生长的影响.从感染线虫的肾茶根系中分离线虫的雌虫、雄虫与幼虫,用显微镜观察描述线虫特征并对照线虫特征图样进行鉴别.通过致病性实验研究线虫对肾茶生长的影响,并通过肾茶的长势、叶绿素、蛋白质含量等指标来评价.分离得到了海南肾茶的根结线虫,并成功进行了致病性实验.实验所用海南肾茶感染的线虫为南方根结线虫(Meloidyne incognita.).线虫严重影响肾茶的生长发育,使肾茶植株长势不良甚至死亡,重要代谢物质如蛋白质、叶绿素a含量明显下降.     

Analysis of survey data

Data from surveys should be weighted using expansion weights to avoid biased estimates for the inference population. Calculation of expansion weights is a stepwise procedure that can be thought of as allowing respondents to represent all eligibles from the population. Design will have an impact on the variance of the estimates. Furthermore, the impact may be to inflate or deflate the variance and is often variable-dependent. Accounting for the design in estimating the variance will require specialized analysis procedures and often specialized software.     

福建省笋竹加工现状调查及发展研究

福建是全国竹子的重点产区，近年来，随着竹林资源的不断发展，竹笋、竹材产量显著提高，笋，竹产品市场供大于求的矛盾逐渐突出。为拓宽笋、竹市场、发展深加工、扩大社会需求量、切实保护竹农培育竹林的积极性，推进竹产业化进程，福建省林业厅于１９９８年８月￣１９９９年４月组织开展了笋竹产品市场，加工现状调查。本文根据调查数据，分析福建省笋竹加工现状，存在问题，提出今后的发展对策。
