“…The variations in the prevalence of virulence markers detected in this study and that observed in other studies may be due to the differences in the origin or source of the isolates. Environmental isolates have the tendencies to be more virulent because they are constantly exposed to single or multiple sub-lethal stress factors such as osmotic stress, cold stress, high hydrostatic pressure, acid stress, and desiccation stress which over time enhances their survival and pathogenesis [58]. This shows that L. monocytogenes isolated in this study are very virulent and capable of causing foodborne disease outbreak when introduced into the food web.…”

Listeria monocytogenes (L. monocytogenes) is a foodborne pathogen and the etiologic agent of listeriosis, which can be disseminated within the agricultural environment particularly soil and irrigation water, contaminate farm produce and cause high mortality and morbidity among vulnerable individuals. This study assessed the incidence and antibiogram of L. monocytogenes recovered from irrigation water and agricultural soil samples collected from Chris Hani and Amathole District Municipalities (DMs) in Eastern Cape Province, South Africa. The distribution of presumptive L. monocytogenes in irrigation water and agricultural soil samples was done using the standard plate count method, while polymerase chain reaction (PCR) was used to identify the isolates. The confirmed isolates were screened for 9 key virulence markers using PCR after which they were subjected to antibiotic susceptibility testing against 18 antibiotics used for the alleviation of listeriosis using the disk diffusion method. Relevant putative antibiotic resistance genes in the resistant variants were screened for using PCR. The distribution of L. monocytogenes in irrigation water samples was statistically significant (P � 0.05) and ranged from log 10

“…In agreement with previous studies, we can speculate that there might be differences in the mechanisms of afferent modulation between passive movements and functional electrical stimulation. Whereas NMES over the motor threshold recruits afferent axons from muscle spindles, Golgi tendon organs and cutaneous receptors (Bergquist et al, 2011;Golaszewski, 2017), Golgi tendon organs are less sensitive to passive movements and discharge less (Paillard and Brouchon, 1968;Purves et al, 2004), and the firing rate of the muscle spindles is muscle lengthening dependent (Chye et al, 2010). However, it cannot be concluded whether our functional NMES induces stronger beta activity than passive movement since we did not include the latter condition in our experimental protocol.…”

Neuromuscular electrical stimulation (NMES) of the peripheral nervous system has been largely used in the field of neurorehabilitation to decrease muscle atrophy and to restore motor function in paralyzed patients. The rehabilitative effects of NMES rely on the direct or indirect efferent effect on muscle tone and afferent volleys that induce cortical excitation. Although different neuroimaging tools suggested the capability of NMES to regulate the excitability of sensorimotor cortex and corticospinal circuits, to date how intensity and dose of NMES can neuromodulate the brain oscillatory activity measured with electroencephalography (EEG) is yet to be clarified. In the present study, we quantify the effect of NMES parameters on brain oscillatory activity of twelve healthy participants who underwent stimulation of wrist extensors during rest while EEG was recorded. Three different NMES intensities were included: (1) low, inducing slight sensory perception, (2) medium, inducing moderate sensory perception, and (3) high, generating a functional movement. Firstly, we efficiently removed stimulation artifacts from the sensorimotor brain oscillatory activity. Secondly, we analyzed the effect of amplitude and dose on the latter. On the one hand, we observed significant NMES amplitude-dependent brain SMR modulation, demonstrating the direct effect of afferent receptors recruitment. On the other hand, our results revealed a significant NMES amplitude-based dose-effect on SMR modulation over time. While at low and medium intensities the NMES produced a significant cortical inhibitory effect in time, at high intensity a significant cortical facilitatory effect was induced. These results highlight the functionally relevant role of muscle contraction and proprioception in sensorimotor processes, which should be carefully considered for the design and development of NMES based neuromodulation.

“…Cardiovascular disease is common in avian species (Beaufrère et al, 2010). The increase in commercial economic losses and demand for healthcare in veterinary centres has resulted in increased research investigating these disorders (Kubale, Merry, Miller, Diaz, & Rutland, 2018). Alterations in nutritional status may result in cardiac structural changes.…”

“…Due to a lack of complete understanding of the nutritional requirements of captive parrots, malnutrition is a concern in this species (Heatley & Cornejo, 2015). Additionally, in commercial breeding, changes in the avian heart cause concern, and the impact of diet on the risk of heart failure in broiler chickens has been investigated to design nutritional plans to maximize growth while reducing the risk of cardiac failure (Kubale et al, 2018).…”

This study aimed to assess radiographic and tomographic cardiac parameters, including width and length of the heart, and the ratio of heart width to coelom width of blue‐fronted Amazon parrots (Amazona aestiva) with varying body condition scores. Thirty‐five captive birds were included in the study and were allocated into one of three groups according to their respective body condition score: lean, ideal and obese. No differences were observed among the groups with regard to radiographic and tomographic measurements. Computed tomography enabled better identification of the structures of the cardiovascular system without interference from the overlying structures of the celomatic cavity observed in radiographic images. However, radiographic examinations should still be considered the standard screening method to identify cardiac alterations, such as increased or reduced organ dimensions. Standardizing the techniques and measurements performed in this study may serve as a basis for further research in the field.
