Monitoring the genetic variation of some Escherichia coli strains in wild birds and cattle.

To date, there is limited data about the genetic relationship of Escherichia coli between wild birds and cattle because these birds act as silent vectors for many zoonotic bacteria. This study aimed to elucidate the role of rooming wild birds in the vicinity of cattle farm in transmission of the same pathogenic E. coli variants, identifying their virulence, resistance traits and genetic similarities of fimH virulence gene.

Effect of induced sublethal intoxication with neonicotinoid insecticides on Egyptian toads (Sclerophrys regularis).

The toxicity role of insecticides affecting nontarget vertebrate of wildlife population has become essential subject to focus on. In this vein, the current study aimed to illustrate some biochemical and histopathological alterations induced by two neonicotinoids in Egyptian toads. Forty-five toads were collected and divided equally into three groups (15 toads/group): control group, thiamethoxam group, and acetamiprid group.

Molecular cloning, expression, purification, and functional characterization of SP-22 gene from Bombyx mori.

Serine protease (SPs) is one of the immune enzyme's molecules that play a main role in the variation of a physiological process by controlling protease actions in vertebrates. For example, signaling cells, protector and improvement, which are included in melanization, are utilized to cascade with the meddling pathogens and defense the harmed tissue in insects. In this study, we explore the biochemical process of (SP-22) from Bombyx mori.

Immune function of a Rab-related protein by modulating the JAK-STAT signaling pathway in the silkworm, Bombyx mori.

The Rab-family GTPases mainly regulate intracellular vesicle transport, and play important roles in the innate immune response in invertebrates. However, the function and signal transduction of Rab proteins in immune reactions remain unclear in silkworms. In this study, we analyzed a Rab-related protein of silkworm Bombyx mori (BmRABRP) by raising antibodies against its bacterially expressed recombinant form.
