摘要

对福塔莱萨(巴西塞埃尔)沿海地区,包括塞埃尔河和Cocó河沿岸地区的细菌情况进行了检查。这项研究是在1993年6月、9月和12月以及1994年3月进行的。该区域分为两个区域:(i)直接影响区(DIA),由靠近海底管道系统排放区的20个采样站组成,在海面进行收集;(ii)间接影响区(IIA),靠近沿海区,包括Barra do cerar 、Kartódromo、Volta de Jurema、Mucuripe、Farol和caa e Pesca海滩,共有26个采样站。DIA中总大肠菌群和粪便大肠菌群的最可能数(MPN)仅在靠近污水排放出口的6号站呈阳性。鉴定出以下细菌:柠檬酸杆菌、产气肠杆菌和大肠杆菌。Kartódromo海滩在整个采样期间都受到污染。结果表明,卡帕拉塔-佩斯卡海滩的总粪便MPN基本低于3.0 × 10(2)个大肠菌群/100 ml。12月,在DIA和IIA的几个样本中都发现了沙门氏菌。在DIA,沙门氏菌的空间分布表明沿海岸线应该存在自东向西的沿海海流。在IIA,在整个采样期间,在Kartódromo和Farol海滩发现了沙门氏菌。

Coliforms and Salmonella in seawater near to domestic sewage sources in Fortaleza (Ceará, Brazil).

The bacteriological conditions of the coastal region of Fortaleza (Ceará, Brasil), including the coastal zones of the Ceará and Cocó rivers, were examined. The study was conducted during June, September and December 1993, and March 1994. The region was divided into two areas: (i) Direct Influence Area (DIA), consisting of 20 sampling stations located near to discharge zones of the submarine pipeline system, where collections were carried out at the surface, and (ii) Indirect Influence Area (IIA), located near to the coastal zone, including Barra do Ceará, Kartódromo, Volta de Jurema, Mucuripe, Farol and Caça e Pesca beaches, totalling 26 sampling stations. The most probable number (MPN) of both total and fecal coliforms in DIA was positive only in station number 6, near to the sewage discharge exit. The following bacteria were identified: Citrobacter sp., Enterobacter aerogenes and Escherichia coli. Kartódromo beach was contaminated throughout the sampling period. Results of total fecal MPN was essentially lower than 3.0 x 10(2) coliforms/100 ml at Caça e Pesca beach. In December, at both DIA and IIA, Salmonella was identified in several samples. In DIA, the spatial distribution for Salmonella suggests that there should be a coastal sea current from east to west along the coastline. In IIA, Salmonella was identified at Kartódromo and Farol beaches throughout the sampling period.
