ABSTRACT Learning and memory are major cognitive processes strongly tied to the life histories of animals. In ants, chemotactile information generally plays a central role in social interaction, navigation resource exploitation. However, hunters, visual should take special relevance during foraging, thus leading differential use from different sensory modalities. Here, we aimed test whether hun...
Actor Network Theory (ANT) is explored as a useful tool in researching the intersection of English teaching and Information Communication Technologies (ICTs), to understand the complex interaction of influences, both human and non-human, that combine to achieve a particular outcome, in this case the uptake of ICTs by English teachers in an Australian school. What this means is that alongside in...
Background & aim: About 40% of women and 12% of men experience a urinary tract infection at least once in their lifetime. Aminoglycosides are very effective antimicrobial agents. The emergence and spread of antibiotic resistance in Escherichia coli (E. coli) is becoming a global public health concern. The aim of this study was to determine the presence of ant(2'')-Ia and ant(4')-IIa genes in E....
Parasitoid insects face considerable trade-offs in locating suitable hosts within complex environments. Apocephalus paraponerae (Diptera: Phoridae) locates its host ant Paraponera clavata (Formicidae: Ponerinae) using olfactory cues. Here, comparing two populations of A. paraponerae, I describe differences in host location cues between two sites, Barro Colorado Island (BCI) in Panama and La Sel...
In the course of our studies on the role of complement in an t i se rum-media ted damage to allografts and xenografts of skin, we have observed that, whereas serum from C5 deficient mice fails, as expected, to lyse sensitized sheep erythrocytes (SRBC),I whole blood from these animals causes measurable lysis even when di luted 1:100 in saline. This lytic activity occurs only if the cells have re...

Background & objective: Multidrug-resistant Acinetobacter baumannii (MDR-AB) is an important nosocomial pathogen which is associated with significant morbidity and mortality, particularly in high-risk populations. Aminoglycoside-modifying enzymes (AMEs) and 16S ribosomal RNA (16S rRNA) methylation are two important mechanisms of resistance to ...
