Acinetobacter Baumannii Infections
Antibiotic resistance is one of the biggest challenges for the clinical sector and industry, environment and societal development. One of the most important pathogens responsible for severe nosocomial infections is Acinetobacter baumannii, a Gram-negative bacterium from the Moraxellaceae family, due to its various resistance mechanisms. The enormous adaptive capacity of A. baumannii and the acquisition and transfer of antibiotic resistance determinants contribute to the ineffectiveness of most current therapeutic strategies, including last-line or combined antibiotic therapy. In this review, we will present the current progress in developing innovative strategies for combating multidrug-resistant A. baumannii (MDRAB) infections.

Acinonychini
The feline tribe Acinonychini contains three genera, each with one extant species: the cougar in Puma, the jaguarundi in Herpailurus, and the cheetah in Acinonyx. In addition, a handful of extinct fossil species have been found in Eurasia and the Americas. The evolutionary relationships of these cats still needs to be worked out, with the main focus being the placement of the extinct species in relation to the extant species, and where cheetahs evolved. While cheetahs and cougars are sometimes considered big cats, as felines, they are more closely related to domestic cats than they are to pantherines such as lions and leopards.

Acnistus Arborescens
[ N.B. the monotypic genus Acnistus was subsumed in the genus Iochroma by J.M.H. Shaw in 2016 and the species formerly known as Acnistus arborescens is now known correctly as Iochroma arborescens (L.) J.M.H. Shaw ]. Acnistus arborescens is a species of flowering plant – the single species in the monotypic genus Acnistus, belonging to the Nightshade family Solanaceae. Common names include gallinero ( = 'henhouse' ), mata-gallina ( = 'chicken-killer' ), fruta-de-sabiá ( = 'thrush-fruit' ), hollowheart, wild tobacco, siyou, bastard sirio, galán arbóreo, tabaco de monte ( = 'mountain tobacco' ), nigüito, marieneira, güitite, and tabak djab ( = 'devil's tobacco' ).

Acoustic Information Exchange
The behavioural, physiological, and energetic repercussions for wildlife that result from changes in their soundscapes are increasingly being realized. To understand the effects of changing acoustic landscapes, people first must establish the importance of the acoustic sense for species to transfer information between the environment, con- and heterospecifics, and a receiver, and the functional role of calling in behaviours such as foraging, navigation, mate attraction, and weaning.

Acquired Cytomegalovirus Infection Hearing Loss
Congenital cytomegalovirus (CMV) infection induces a clinical syndrome usually associated with hearing loss. However, the effect of acquired CVM infection in adults and children has not been clearly defined.

Acquisition of Brassica Yellows Virus
Brassica yellows virus (BrYV) is a tentative species of the genus Polerovirus, which occurs widely, and mostly damages Brassicaceae plants in East Asia. Because BrYV cannot be transmitted mechanically, an insect-based transmission method is required for further virus research. Here, a reliable and unrestricted method is described, in which non-viruliferous aphids (Myzus persicae) acquired BrYV from transgenic Arabidopsis thaliana, harboring the full-length viral genome germinated from seeds and its frozen leaves. The aphids then transmitted the virus to healthy plants. There was no significant difference in acquisition rates between fresh and frozen infected leaves, although the transmission rate from frozen infected leaves was lower compared to fresh infected leaves. This simple novel method may be used to preserve viral inocula, evaluate host varietal resistance to BrYV, and investigate interactions among BrYV, aphids, and hosts.

Acraea (Genus)
Acraea is a genus of brush-footed butterflies (family Nymphalidae) of the subfamily Heliconiinae. It seems to be highly paraphyletic and has long been used as a "wastebin taxon" to unite about 220 species of anatomically conservative Acraeini. Some phylogenetic studies show that the genus Acraea is monophyletic if Bematistes and Neotropical Actinote are included (see Pierre & Bernaud, 2009). Most species assembled here are restricted to the Afrotropic ecozone, but some are found in India , Southeast Asia, and Australia .

Acremonium Strictum
Acremonium strictum is an environmentally widespread saprotroph species found in soil, plant debris, and rotting mushrooms. Isolates have been collected in North and Central America, Asia, Europe and Egypt. A. strictum is an agent of hyalohyphomycosis and has been identified as an increasingly frequent human pathogen in immunosuppressed individuals, causing localized, disseminated and invasive infections. Although extremely rare, A. strictum can infect immunocompetent individuals, as well as neonates. Due to the growing number of infections caused by A. strictum in the past few years, the need for new medical techniques in the identification of the fungus as well as for the treatment of human infections has risen considerably. A. strictum has been shown to be involved in some myoparasitic relationships, as well as a wide range of plant endophytic and parasitic relationships, and further studies are required to determine A. strictum's use as a biological control agent and role as a parasite that reduces crop yields. A. strictum exhibits metabolism of many products that imply future agricultural and pharmaceutical significance.
