2014
Nabeel Abd Murad Al-Mamoori
The present study has been out to examine macroscopic structure of the primary bronchi and lung in Bee-eaters bird ( Merops orientalis) observed exist within the rib cage, the distal part of the trachea are divided into two primary bronchi (left and right) and the macroscopic appearance of the primary bronchi consists of a short tube extend caudally from syrinx to enter the proximal third of the visceral surface of the lungs through the hilus. The basic unit consisting of the primary bronchi are cartilaginous rings which takes - C - shape. The mean total length of left and right primary bronchi are (1.025 ± 0.15 cm) and (1.075 ± 0.14 cm); and the number of cartilaginous rings in left and right primary bronchi are ( 18.5 ± 0.50) and (18.5 ± 1.50). The lungs are small, pyramidal-shaped, unlobed, bright pink color, and surrounded by thin colorless membrane the pleura and the air sacs. The lung contains two surfaces (dorsal and ventral), two borders ( medial and lateral) and two extremities ( proximal and distal ). The mean total length, width and thickness of the right lung are (1.77 ± 0.17 cm), (0.95 ± 0.15 cm) and (0.4 ± 0.10 cm) while the mean total length, width and thickness of the left lung are (1.6 ± 0.15 cm ), ( 0.9 ± 0.14 cm ) and (0.37 ± 0.02 cm ).

In order to determine the genotoxic effects of diazinon and the role of chitosan to neutralize these effects, our study performed in (24) male rats (Rattus norvegicus) were divided into four groups and treated for (60) days as following, group (A) treated with normal saline and served as control, group (B) treated with [(1/10LD50) 3.8mg/kg. bw] of diazinon, group (C) treated with [(1/10LD50) 3.8mg/kg. bw] of diazinon and fed on diet supplement containing (1gram/1kg ration) chitosan, group (D) fed on diet supplement containing (1gram/1kg ration) chitosan only. The genotoxic effect of diazinon was evaluated by using the micronucleus assay showed increasing of micronucleated polychromatic erythrocytes were (11.6%) in group B, while (7%) in group C . The chromosomal aberration showed increase of presence of chromosomal aberration in group B was (7.5±1.04), while in the group C showed mild elevation in (3.25±0.8). The polymorphism of GSTM1 and GSTT1 genes showed highly incidence of both genes polymorphism in group B was (66.6%) while group C was (50%) . we concluded that diazinon is genotoxic pesticide and chitosan ameliorate it effects.

Advocacy for neglected zoonotic diseases (ADVANZ) is a One Health Neglected Zoonotic Diseases (NZDs) project, funded by the European Commission through its 7th framework programme. The initiative aims at persuading decision makers and empowering stakeholders at local, regional, and international levels towards a coordinated fight against NZDs. ADVANZ is establishing an African platform to share experiences in the prevention and control of NZDs. The platform will compile and package existing knowledge or data on NZDs and generate evidence-based algorithms for improving surveillance and control with the ultimate aim of eliminating and eradicating these diseases. The platform will serve as a forum for African and international stakeholders, as well as existing One Health and NZD networks and harness and consolidate their efforts in the control and prevention of NZDs. The platform had its first meeting in Johannesburg, South Africa in March 2013.

The quest for One Health: Human Resource training aspects Full text
2014
Angwara Kiwara | Ave-Maria Semakafu | Gasto Frumence
Appropriately trained Human Resources for Health (HRH) are key inputs into One Health. ‘… more than 50% of all infectious diseases of humans originate from animals and that, of the emerging diseases about 75% could be traced back to animal origin’ (Rweyemamu et al. 2006). A comprehensive understanding of the social determinants of health, through an appropriate training model for HRH, is a key input. This study aimed to explore if human and veterinary medical schools were using such a model or providing time for this model in their curricula. Specific objectives were to: determine the time that human and veterinary medical schools’ curricula provide for subjects or courses related to the social determinants of health; analyse the curricula contents to establish how they relate to the social determinants of health; and explore how a bio-medical model may influence the graduates’ understanding and practice of One Health. A review of human and veterinary graduate-level medical schools’ curricula in East Africa was performed in April 2013 and May 2013. The findings were: in the curricula, SDH contents for knowledge enhancement about One Health are minimal and that teaching is Germ Theory model-driven and partisan. Out of the total training time for physicians and veterinarians, less than 10% was provided for the social determinants of health-related courses. In conclusion, the curricula and training times provided are inadequate for graduates to fully understand the social determinants of health and their role in One Health. Furthermore, the Germ Theory model that has been adopted addresses secondary causes and is inappropriate. There is a need for more in-depth model. This article suggests that a vicious cycle of ill-health model must be taught.

Phylogeography data are of paramount importance in studying the molecular epidemiology dynamics of foot-and-mouth disease virus (FMDV). In this study, epithelial samples and oesophageal-pharyngeal fluids were collected from 361 convalescent animals (cattle and buffaloes) in the field throughout Tanzania between 2009 and 2013. The single plex real-time RT-PCR (qRT-PCR) assay for rapid and accurate diagnosis of FMDV employing the Callahan 3DF-2, 3DF-R primers and Callahan 3DP-1 probe were used. Preparation of the samples was performed according to the OIE manual, with a Kenya O serotype obtained from the attenuated vaccine serving as a positive control and samples collected from healthy animals serving as true negatives. The results indicated that 53.49% of samples (n = 176) were positive for FMDV genome by qRT-PCR, with Ct values ranging from 14 to 32. In addition, molecular typing of the FMDV genome positive samples using serotype specific primers revealed the existence of several serotypes: serotype South Africa Territory 1 (SAT1) (34.25%, n = 60), serotype A (68.92%, n = 98), serotype O (59.20%, n = 98) and SAT2 (54.54%, n = 96). The virus protein 1 sequences analysis for 35 samples was performed and the collective results indicated: 54.28% serotype O, 25.71% serotype A, 14.28% serotype SAT1 and 2.85% serotype SAT2. Therefore in this study, both the phylogenetic trees and spatial distribution of serotypes elucidated the phylodynamics of multiple FMDV field strains in Tanzania and neighbouring countries.

Pharmacokinetics and pharmacodynamics of a constant rate infusion of fentanyl (5 μg/kg/h) in awake cats Full text
2014
Ambros, Barbara | Alcorn, Jane | Duke-Novakovski, Tanya | Livingston, Alexander | Dowling, Patricia M.
Objective—To evaluate the pharmacokinetics and thermal and mechanical antinociceptive effects of a fentanyl constant rate infusion (CRI) in conscious cats. Animals—8 healthy adult cats. Procedures—At a ≥ 14-day interval, 7 cats received a loading dose (LD) of fentanyl (5 μg/kg, IV [administered at 0 hours]) followed by fentanyl infusion (5 μg/kg/h, IV) for 2 hours or similar administrations of equivalent volumes of 0.9% saline (NaCl) solution. One cat received only the fentanyl treatment. For both treatments, sedation and adverse events were evaluated and mechanical threshold (MT) and thermal threshold (TT) testing was performed prior to (baseline) and at predetermined times up to 26 hours after LD administration; plasma fentanyl concentrations were determined at similar times when the cats received fentanyl. Results—Fentanyl induced mild sedation during the infusion. The only adverse effect associated with fentanyl LD administration was profuse salivation (1 cat). Saline solution administration did not significantly change MT or TT over time. For the duration of the CRI, MT and TT differed significantly between treatments, except for TT 1 hour after LD administration. For the fentanyl treatment, MT and TT were significantly higher than baseline at 0.25 to 0.75 hours and at 0.25 to 1 hour, respectively. During the fentanyl CRI, mean ± SD plasma fentanyl concentration decreased from 4.41 ± 1.86 ng/mL to 2.99 ± 1.28 ng/mL and was correlated with antinociception; plasma concentrations < 1.33 ± 0.30 ng/mL were not associated with antinociception. Conclusions and Clinical Relevance—Fentanyl CRI (5 μg/kg/h) induced mechanical and thermal antinociception in cats.
