While both human and animal trypanosomiasis continue to present as major human and animal public health constraints globally, detailed analyses of trypanosome wildlife reservoir hosts remain sparse. African animal trypanosomiasis (AAT) affects both livestock and wildlife carrying a significant risk of spillover and cross-transmission of species and strains between populations. Increased human activity together with pressure on land resources is increasing wildlife–livestock–human infections. Increasing proximity between human settlements and grazing lands to wildlife reserves and game parks only serves to exacerbate zoonotic risk. Communities living and maintaining livestock on the fringes of wildlife-rich ecosystems require to have in place methods of vector control for prevention of AAT transmission and for the treatment of their livestock. Major Trypanosoma spp. include Trypanosoma brucei rhodesiense, Trypanosoma brucei gambiense, and Trypanosoma cruzi, pathogenic for humans, and Trypanosoma vivax, Trypanosoma congolense, Trypanosoma evansi, Trypanosoma brucei brucei, Trypanosoma dionisii, Trypanosoma thomasbancrofti, Trypanosma elephantis, Trypanosoma vegrandis, Trypanosoma copemani, Trypanosoma irwini, Trypanosoma copemani, Trypanosoma gilletti, Trypanosoma theileri, Trypanosoma godfreyi, Trypansoma simiae, and Trypanosoma (Megatrypanum) pestanai. Wildlife hosts for the trypansomatidae include subfamilies of Bovinae, Suidae, Pantherinae, Equidae, Alcephinae, Cercopithecinae, Crocodilinae, Pteropodidae, Peramelidae, Sigmodontidae, and Meliphagidae. Wildlife species are generally considered tolerant to trypanosome infection following centuries of coexistence of vectors and wildlife hosts. Tolerance is influenced by age, sex, species, and physiological condition and parasite challenge. Cyclic transmission through Glossina species occurs for T. congolense, T. simiae, T. vivax, T. brucei, and T. b. rhodesiense, T. b. gambiense, and within Reduviid bugs for T. cruzi. T. evansi is mechanically transmitted, and T. vixax is also commonly transmitted by biting flies including tsetse. Wildlife animal species serve as long-term reservoirs of infection, but the delicate acquired balance between trypanotolerance and trypanosome challenge can be disrupted by an increase in challenge and/or the introduction of new more virulent species into the ecosystem. There is a need to protect wildlife, animal, and human populations from the infectious consequences of encroachment to preserve and protect these populations. In this review, we explore the ecology and epidemiology of Trypanosoma spp. in wildlife.

Background:Surgery for hypertrophied breasts represents a challenge for plastic surgeons. The search for a good post-surgical cosmetic breast has led to the development of many techniques. Objectives for reduction mammoplasty are to achieve elevated, symmetrical breasts, a round shape, good projection, small cicatrices that are not very perceptible, and a lasting result.Patients and Methods:This study was carried out on sixty cases who had done reduction mammoplasty from January 2009 to December 2014. All patients were examined and were asked for late post-operative results and overall patients' satisfaction.Results:Long-term projection and contour of the breast were more satisfactory among patients who had superomedial pedicle with a statistically significant difference. No statistically significant difference was observed between patients underwent either superomedial or inferior pedicle reduction mammoplasty with regard to breast shape symmetry, nipple symmetry and sensation. The mean score for satisfaction was higher among patients who underwent superomedial pedicle rather than the inferior pedicle method.Conclusion:The superomedial pedicle shows better long-term cosmetic results.

Limited pharmacological studies have been conducted on plant species used against poultry helminths. The objective of this study was to provide a basis for plant based anthelmintics as possible alternatives against poultry anthelmintic resistance. The study justified the need for alternative anthelmintics. The study places emphasis on the increasing anthelmintic resistance, mechanism of resistance, and preparational protocols for plant anthelmintics and their associated mechanism of action. Pharmaceutical studies on plants as alternative therapies for the control of helminth parasites have not been fully explored especially in several developing countries. Plants from a broad range of species produce a wide variety of compounds that are potential anthelmintics candidates. Important phenolic acids have been found in Brassica rapa L. and Terminalia avicenniodes Guill. and Perri that affect the cell signaling pathways and gene expression. Benzo (c) phenanthridine and isoquinoline alkaloids are neurotoxic to helminths. Steroidal saponins (polyphyllin D and dioscin) interact with helminthic mitochondrial activity, alter cell membrane permeability, vacuolation and membrane damage. Benzyl isothiocyanate glucosinolates interfere with DNA replication and protein expression, while isoflavones from Acacia oxyphylla cause helminth flaccid paralysis, inhibit energy generation, and affect calcium utilization. Condensed tannins have been shown to cause the death of nematodes and paralysis leading to expulsion from the gastro-intestinal tract. Flavonoids from Chenopodium album L and Mangifera indica L act through the action of phosphodiesterase and Ca2+-ATPase, and flavonoids and tannins have been shown to act synergistically and are complementary to praziquantel. Artemisinins from Artemisia cina O. Berg are known to disrupt mitochondrial ATP production. Terpenoids from Cucurbita moschata L disrupt neurotransmission leading to paralysis as well as disruption of egg hatching. Yeast particle encapsulated terpenes are effective for the control of albendazole-resistant helminths.

This study was done to determine the impact of monieziosis infection combined with hypomicroelementosis on some hematological, biochemical and hormonal parameters of Soviet Merino sheep in the Astrakhan region. 20 sheep, aging 3 years old and average 43±1.6 kg body weight were used. Sheep were divided into two groups. First group contained 10 sheep and these sheep were naturally infected with monieziosis and clinically were suffered from hypomicroelementosis, emaciation, reduced growth rate, anemia, diarrhea and pale mucosa. Second group contained 10 sheep were apparently healthy and free from internal parasites and they were used as a control group. The first group was given Praziver (praziquantel and ivermectin) for treatment monieziosis, while they intramuscularly injected with Sedimin (selenium, iodine and iron) and were introduced daily into the feed with CoCl2. Faecal and blood samples from both groups were collected, before and 30 days after treatment, and analyzed for some hematological, biochemical and hormonal parameters. Our results revealed that there was a significant decrease in Hb and RBCs values, while total WBCs and eosinophils were significantly increased in the diseased group than in healthy one. Biochemical analysis showed a significant decrease in serum antioxidant enzymes (CAT, SOD and GSH-Px) and a significant increase in serum DC and MDA in the diseased group as compared with the control group. Hormonal analysis showed a significant increase in ACTH, TSH, Cortisol and a significant decrease in serum T4 and T3. After treatment with Praziver, Sedemin and CoCl2, there was a significant effectiveness to maintain blood parameters within normal levels in the experimental group and increase reproductive outcome from these sheep

Background: Meningomyelocele reconstruction is a lifesaving procedure. A freestyle propeller perforator flap is an ideal option for moderate to large soft tissue meningomyelocele reconstruction. Previous studies that focused on the reliability of perforator flaps for meningomyelocele reconstruction recommended preserving a cuff of soft tissue around the perforators to avoid vasospasm. This method is a very conservative approach in comparison to the recently well-established principles of pedicled perforator flap dissection. In this study, we used a dissection ladder approach. In this method, the pedicle is freed by just islanding the pedicle, skeletonization of the perforator, or further dissection of the perforators beyond the muscles, based on intraoperatively monitoring of the flap. Materials and Methods: Thirty-six infants with a mean age of 2.1 ± 1.1 months underwent surgery for dorsolumbar meningomyelocele at Assuit University Hospital for 3 years. During surgery, the freestyle perforator flap followed a dissection ladder for perforating vessels and intraoperative flap monitoring. Flap viability, seroma, hematoma, and cerebrospinal fluid leakage were evaluated. Results: Nine cases required perforator skeletonization, 4 cases required dissection beyond the muscle, and 23 cases required islanding the flap on the perforators. The average operative time was 43.37 ± 7.87 minutes. Partial tip ischemia was detected in 2 cases. These cases exhibited partial dehiscence and healed by secondary intention. Complete flap loss did not occur in any cases. Conclusions: A conservative approach for perforator flap elevation in infants did not provide optimal results in all cases of thoracolumbar meningomyelocele reconstructions. Well-established principles of perforator dissection, including skeletonization and dissection beyond the muscle, are safe, prevent vasospasms, and improve flap viability.
