S. gregaria is able to swarm and disseminate bacterial load over vast areas. Adult locusts were collected from Kingdom of Saudi Arabia (KSA), individual locust was divided into head, thorax and abdomen. External and internal cultivable bacteria were cultured, cell and colony characteristics were investigated. Pure colonies were sequenced using 16S rRNA. Sequences and phylogeny were analyzed. Using morphological and molecular results, 9 bacterial genera belonging to 5 families, 3 orders, 2 classes, and 2 phyla were recorded. Ribosomal Database Project (RDP) Classifier succeeded to confirm 8 out of 9 genera. The ninth isolate was designated as unclassified. To specify a genus to its closest species, 16S rRNA genes of the type species have been downloaded. Phylogenetic tree was generated using all available sequences. Similarity measures and phylogenetic trees were used to place each genus to its closest species. Six genera created similarities less than 98% to related species. Generally, analyses of 16S rRNA gene succeeded to identify 3 isolates to species level, 5 isolates to genus level and designated one isolate “unclassified”. Investigations are recommended to place all genera to their operational taxonomic units (OTU). Significance of our findings relies on the impact of locust-microbiota on heath of people who consumed insects as food. Bacterial species which were internally, isolated from abdomen were described beneficial commensals. Bacterial species which were internally, isolated from thorax and head were described non-pathogenic beneficial endosymbionts, except Bacillus sp. Salmonella sp. was isolated as external species and was described external contaminant of the locust.

葡萄球菌能够在广阔的地区聚集并传播细菌。蝗虫是从沙特阿拉伯王国（KSA）收集的，蝗虫分为头，胸和腹部。培养外部和内部可培养细菌，研究细胞和菌落特性。使用16S rRNA对纯菌落进行测序。分析了序列和系统发育。使用形态学和分子结果，记录了属于5个科，3个科，2个类和2个门的9个细菌属。核糖体数据库项目（RDP）分类器成功确认了9个属中的8个。第九个隔离株被指定为未分类。为了指定最接近其物种的属，已下载了该类型物种的16S rRNA基因。系统发育树是使用所有可用序列生成的。使用相似性度量和系统发育树将每个属置于最接近的物种。六个属与相关物种的相似度不到98％。通常，对16S rRNA基因的分析成功地鉴定出3种达到物种水平的分离株，5种达到属水平的分离株，并将一种分离株指定为“未分类”。建议进行调查以将所有属放入其操作分类单位（OTU）。我们研究结果的重要意义在于蝗虫微生物群对以昆虫为食的人们的健康状况的影响。描述了从腹部内部分离出的细菌种类，这是有益的。从胸部和头部分离出的内部细菌物种被描述为非致病性有益共生菌，除了 六个属与相关物种的相似度不到98％。通常，对16S rRNA基因的分析成功地鉴定出3种达到物种水平的分离株，5种达到属水平的分离株，并将一种分离株指定为“未分类”。建议进行调查以将所有属放入其操作分类单位（OTU）。我们研究结果的重要意义在于蝗虫微生物群对以昆虫为食的人们的健康状况的影响。描述了从腹部内部分离出的细菌种类，这是有益的。从胸部和头部分离出的内部细菌物种被描述为非致病性有益共生体，除了 六个属与相关物种的相似度不到98％。通常，对16S rRNA基因的分析成功地鉴定出3种达到物种水平的分离株，5种达到属水平的分离株，并将一种分离株指定为“未分类”。建议进行调查以将所有属放入其操作分类单位（OTU）。我们研究结果的重要意义在于蝗虫微生物群对以昆虫为食的人们的健康状况的影响。描述了从腹部内部分离出的细菌种类，这是有益的。从胸部和头部分离出的内部细菌物种被描述为非致病性有益共生菌，除了 建议进行调查以将所有属放入其操作分类单位（OTU）。我们研究结果的重要意义在于蝗虫微生物群对以昆虫为食的人们的健康状况的影响。描述了从腹部内部分离出的细菌种类，这是有益的。从胸部和头部分离出的内部细菌物种被描述为非致病性有益共生菌，除了 建议进行调查以将所有属放入其操作分类单位（OTU）。我们研究结果的意义取决于刺槐微生物群对以昆虫为食的人们的健康状况的影响。描述了从腹部内部分离出的细菌种类，这是有益的。从胸部和头部分离出的内部细菌物种被描述为非致病性有益共生菌，除了芽孢杆菌属。沙门氏菌属。被分离为外部物种，并被描述为蝗虫的外部污染物。
