This study assessed the antimicrobial susceptibility of 51 Listeria ivanovii and 33 Enterobacter cloacae strains isolated from various ready-to-eat foods sold in Alice, South Africa. Isolates were identified using standard microbiological tests and further confirmed using API 20E and API Listeria kits. The disc diffusion technique was used to screen for antimicrobial susceptibility against 15 a...

In this study, a total of 54 Vibrio alginolyticus strains were analyzed. The isolates were recovered from different compartments of the Ruditapes decussatus hatchery in the National Institute of Marine Sciences and Technologies, Monastir, Tunisia. All isolates were biochemically identified (API 20E and API ZYM strips), characterized by amplification of the Hsp-40 gene polymerase chain reaction ...

SYNOPSIS. The regulation of the ecdysteroid-induced cascade of transcription factors by 20-hydroxyecdysone (20E) and juvenile hormone (JH) in the epidermis of the lepidopteran Manduca sexta is summarized. Both the levels and isoforms of the ecdysone receptor (EcR) and Ultraspiracle (USP) change during the molt. The 20E induction of MHR3, an orphan receptor that appears relatively late in the ca...

Por lo tanto, es importante generar informacion sobre los posibles riesgos para las la salud humana. Se realizaron cinco monitoreos mensuales con capturas Chelonia mydas complejo lagunar Ojo Liebre. les p...

The prothoracic glands of early last (fifth) instar larvae of the silkworm are inactive with regard to ecdysteroidogenesis and unresponsive to prothoracicotropic hormone (PTTH) [J. Insect Physiol. 31 (1985) 455]. In an attempt to elucidate the hormonal mechanisms that cause the inactivity, we compared the effects of PTTH, dibutyryl cyclic AMP (dbcAMP), a cAMP phosphodiesterase inhibitor (IBMX),...

A Leptinotarsa decemlineata SLC6 NAT gene (LdNAT1) was cloned. LdNAT1 was highly expressed in the larval alimentary canal especially midgut. LdNAT1 mRNA levels were high right after the molt and low just before the molt. JH and a JH analog pyriproxyfen activated LdNAT1 expression. RNAi of an allatostatin gene LdAS-C increased JH and upregulated LdNAT1 transcription. Conversely, silencing of a J...

In both vertebrates and insects, developmental transition from the juvenile stage to adulthood is regulated by steroid hormones. In insects, the steroid hormone, 20-hydroxyecdysone (20E), elicits metamorphosis, thus promoting this transition, while the sesquiterpenoid juvenile hormone (JH) antagonizes 20E signaling to prevent precocious metamorphosis during the larval stages. However, not much ...

BACKGROUND & OBJECTIVES Optic neuritis (ON) is characterized by sudden and rapid impairment of vision. Bartonella henselae is a known aetiological agent of cat scratch disease (CSD), which is a common cause of neuroretinitis, the least common type of optic neuritis. The present study was carried out to determine the microbiological aetiology of optic neuritis in patients attending a tertiary ca...
