Bronchoalveolar lavage fluid cytological findings in healthy Amiata donkeys

Background: The approach to respiratory diseases in donkeys is similar to that for horses; nevertheless, Bronchoalveolar lavage fluid (BALF) and tracheal wash cytology in this species have been described only a few times in the literature. Aim: To describe BALF cytological findings in a cohort of 24 healthy Amiata donkeys. Methods: Bronchoalveolar lavage (BAL) was carried out via standing sedation with a large animal where the BAL catheter passed blindly through the nasal passage into the trachea. Results: The total nucleated cell count of the BALF was found similar to that already described in healthy horses and donkeys. No differences in the differential count were observed according to age and sex. A decreased macrophage percentage and an increased eosinophil percentage were observed in our donkey population when compared to the existing reference range for horses. Conclusion: The reference intervals for BAL cytology in donkeys may be significantly different for those referred for horses.

Electroacupuncture anesthesia for laparotomy in goats

Background: The objective of the study to evaluate the effect of electroacupuncture during laparotomy in goats. Aim: To study the abdominal anesthesia in goats by electroacupuncture using the physiological variables, vital parameters, hematological, biochemical, cortisol hormone, pain threshold, and wound healing for laparotomy in goats. Methods: Fifteen healthy adult bucks were used to receive electroacupuncture in 10 newly selected acupoints. The data (M ± SD) were assessed at intervals (0 minutes) before induction (control group), (5 minutes), (10 minutes), (15 minutes), and (20 minutes) during induction, (30 minutes), (45 minutes), and (60 minutes) throughout surgery and (24 hours) after surgery, cortisol levels in serum at (0), (24 hours), and (72 hours) throughout laparotomy. Results: The goats of the study showed improvement in the rates of eyelid closure, head, and neck relaxation, rumen motility, and tympany which were graded into mild (+), moderate (++), and severe (+++) degrees. The respiratory rates, body temperatures, and capillary fill times were not significantly different. The total mean of hematocrit was (19.9 ± 2.68), the total mean of hemoglobin was (9.9 ± 0.94), the total mean of red blood cells was (7.9 ± 0.8), the total mean of platelets was (244,861.3 ± 138,444.8) and the total mean of SPO2 was (70.5 ± 4.6). ALT and AST showed no significance. The significant mean cortisol level was (2.6 ± 2.01) and the significant mean pain threshold level was (0.02 ± 0.03). The results proved that electroacupuncture had a lot of significant parameters. The wound healing was improved by early epithelization and immature granulation tissue (at 7 days). Thick keratinized epithelization and collagen deposition in the dermal tissue with enhanced angiogenesis (at 14 days). Mild restoration of skin and the dermal tissue was well-organized (at 21 days). Besides, well-formed scar tissue covering a highly cellular organized dermal tissue (at 28 days). Conclusions: Electroacupuncture had been considered a powerful anesthetic for abdominal surgery in goats. Moreover, wound healing proved excellent and better healing.

Low semen quality and adverse histological changes in testes of adult male mice treated with bee venom (Apis mellifera)

Background: Male infertility has been on the rise since the past seven decades. Recently, in Libya, bee venom therapy (BVT) has become a popular method among alternative healthcare practitioners for treating male infertility. However, a literature search did not find any published studies that investigated the use of BVT for infertility treatment. Aim: To investigate the effect of bee venom on the male reproductive status through measurements of semen quality parameters and testicular histological changes in adult male mice. Methods: A total of 48 male mice were randomly divided into three experimental groups (which were subdivided into two subgroups with eight mice each) as follows: control, bee venom sting (BVS), and bee venom injection (BVI). The normal control subgroup mice were not subjected to any treatment, while the vehicle control subgroup mice were injected (i.p.) with 200 μl of 0.9% saline solution. In the BVS-treated subgroups, each mouse was stung by one live bee for five times (BVS-5) or seven times (BVS-7) every third day for 2 or 3 weeks. While each mouse in the BVI-treated subgroups received 23 μg/kg in a dose volume of 200 μl BVIs (i.p.) for five times (BVI-5) or seven times (BVI-7) every third day for 15 or 21 days. Results: The findings of this study showed that repeated bee venom treatment by sting or injection to adult male mice resulted in a significant decline in testosterone levels, sperm count, sperm motility, and a very significant increase in the percentage of abnormal sperm morphology; also, there were harmful testicular histological changes in the structural organization of seminiferous tubules and degenerative changes in the germinal epithelium compared to control group. Conclusion: The results of this study provide evidence for the low semen quality and adverse testicular histological changes in male mice treated with bee venom. Hence, there is a desperate need for educating alternative healthcare practitioners and infertile couples about the harmful effects of BVT on reproductive status.

A-scan biometry, phacoemulsification, and foldable intraocular lens implantation in a young orangutan (Pongo pygmaeus)

Background: Cataracts are the major cause of visual impairment in animals which can be curable by surgical treatment. Phacoemulsification is the standard technique for cataract treatment that is applied to almost all species with a high success rate. Case Description: A 2-year-old intact female orangutan (Pongo pygmaeus) was presented for the study having bilateral opacity of the lenses, for 2 weeks. Ophthalmic examination revealed mature cataract OU. Ocular biometry measurements using A-scan ultrasonography for appropriate intraocular lens (IOL) refractive power calculation were carried out. Electroretinography was applied to ensure retinal function is intact. The orangutan underwent phacoemulsification OU and +24 diopter IOL implantation OS to restore vision. IOL implantation was not carried out OD because of a posterior capsular tear. Retinoscopy after 3 weeks postoperatively revealed +2.0 diopters OS. The outcome of the cataract surgery was successful during 3 years follow-up. The orangutan lived with other orangutans and was alert with normal behavior such as catching food, climbing trees, and swinging hand over hand from one branch to another. Conclusion: Cataract surgery with phacoemulsification OU and adjusted IOL implantation OD was successful with few complications in this orangutan. Vision was restored with normal behavior, even though an adjusted IOL was inserted in only one eye.

Therapeutic equivalence of ivermectin 1% and two novel formulations combined of ivermectin 1% + fluazuron 12.5% for the control of Rhipicephalus (Boophilus) microplus in beef cattle from Uruguay

Background: Novel combinations of ivermectin (IVM) and fluazuron (FLU) are presented as an alternative for the control of ticks in cattle. Applying a combination of drugs with the aim to affect different stages of the parasite’s life cycle is established as a potential measure to achieve the control of ticks in cattle. Aim: To determine the therapeutic equivalence between two novel formulations of IVM 1% combined with FLU 12.5% tested on bovines naturally infested with Rhipicephalus (Boophilus) microplus. Methods: Forty adult beef cattle were randomized into four groups (n = 10): IVM [1% (0.2 mg/kg)], combinations groups A and B [IVM 1% (0.2 mg/kg) + FLU 12.5% (2.5 mg/kg), each], and control [untreated]). On days 14, 27, and 49 after administration, the presence of ticks was ranked as null, low, medium, and high; a cumulative link model was adjusted to evaluate treatment response. Results: Although all groups had some animals with the presence of ticks until day 27, on day 14 IVM [odds ratios (OR) 0.013, CI95%: 0.001–0.014, p < 0.01], A (OR 0.01, CI95%: 0.00–0.07, p < 0.01) and B (OR 0.01, CI95%: 0.00–0.148, p < 0.01) groups were different when compared to the control group, unlike on day 27 where only groups A (OR 0.02, CI95%: 0.00–0.17, p < 0.01) and B (OR 0.06, CI95%: 0.00–0.46, p < 0.01) remained different from the control group. On day 49 post-administration, IVM and B did not differ from the control group, with 0.95 probability (CI95% 0.92–1.02) of high parasite burden. At day 49 post-administration, group A was the only group free of ticks (OR 0.01, CI95%: 0.00–0.13, p < 0.01). Conclusions: Pharmacotechnical differences in combined formulations should be considered in therapeutic equivalence studies.

The bioavailability of cytarabine in dogs with meningoencephalitis of unknown etiology through iontophoresis and rectal delivery

Background: Cytarabine (CA) is used to treat dogs with meningoencephalitis of unknown etiology (MUE) by subcutaneous or intravenous administration. Aim: The objective was to investigate transdermal iontophoresis and rectal administration as alternative routes of CA delivery. Methods: Two client-owned dogs with MUE were studied. The ActivaPatch® IONTOGOTM 12.0 iontophoresis drug delivery system delivered 200 mg/m2 CA transdermally. Blood samples were collected by sparse sampling technique after initiation of the device. At another visit, 100 mg/m2 CA was administered rectally. Blood samples were collected by sparse sampling technique after administration. Plasma CA concentrations were measured by high-pressure liquid chromatography. Results: The concentration of plasma CA after transdermal and rectal administration was below the limits of quantification (0.1 μg/ml) in all samples suggesting inadequate bioavailability with transdermal and rectal administration. Conclusion: Transdermal and rectal CA administration are not reasonable alternative routes of delivery.

Green Coffea robusta (Coffea canephora) from Lampung province effect toward free radicals in chickens infected with Salmonella enteritidis bacteria

Background: Foodborne diseases are caused by acquired pathogenic bacteria such as Salmonella enteritidis. It causes an intestinal imbalance and the microbial toxins found in the gastrointestinal tract induce symptoms such as diarrhea. Coffee contains active ingredients such as antioxidants and is used as an anti-inflammatory agent by reducing pro-inflammatory cytokine levels in the body. Aim: The purpose of this study was to determine the interaction between Lampung’s robusta coffee and tissue damage in chickens infected by S. enteritidis. Methods: This study used first-day-old Isa brown layer chickens (n = 60), which were divided into five treatment groups. The negative control group consisted of healthy and normal chickens, whereas the positive control group consisted of chickens infected with S. enteritidis bacteria at a concentration of 108 CFU/ml. Groups T1, T2, and T3 were given coffee extract with doses of 500 mg/kg BW (low dose), 1,000 mg/kg BW (moderate dose), and 1,500 mg/kg BW (high dose), respectively, and then infected with S. enteritidis bacteria at a concentration of 108 CFU/ml. The coffee extract and bacteria were given orally via a feeding tube at a volume of 0.5 ml per chick. The extract was given for 14 days (from day 3 to day 16), and the bacteria were given on days 16 and 17. On day 18, the chickens were necropsied. The malondialdehyde (MDA) level was analyzed using one-way analysis of variance test with the GLM procedure (<0.05), while the tissue histopath was analyzed using a descriptive qualitative study to examine the ileal damage Results: The results showed that the MDA levels (nmol/l) decreased in treatment groups T1, T2, and T3 compared to the positive control. On the contrary, we found improvements in the ileum histopathology of group T1 and T2 in the form of normal and regular intestinal epithelium arrangement of the ileum, long intestinal villi, and decreased total leukocytes. Conclusion: Green coffee robusta has the potential to increase antioxidants and reduce inflammation in the small intestine of chickens infected with S. enteritidis.

Rabies in bovine: First case report of rabies in Al Jabal Al Akhdar, Libya

Background: Rabies is still one of the most neglected diseases in developing countries. It is endemic to North Africa, although rabies incidence in North Africa is certainly underestimated. Case Description: On 18 December 2018 in the region of Al-Jabal Al-Akhdar, an 8-month-old calf died after a period of characteristic clinical symptoms of rabies. This is the first case of rabies in bovine which is confirmed through histopathological examination in the Laboratory of Veterinary Pathology, Omar Al-Mukhtar University. Microscopic examination clearly revealed encephalitis with the pathognomonic Negri bodies in the cerebellar neurons. Conclusion: Since the characteristic lesions in the histopathological examination are sufficient to confirm the diagnosis and report infected cases, we recommend that the next version of the OIE Terrestrial Manual should add and clarify that the results of the use of histopathological techniques in the diagnosis of rabies are significant.

Little brainiacs and big dummies: Are we selecting for stupid, stout, or small dogs?

Background: Brain size has been associated with intelligence of various orders and families of animals, leading to the concept of encephalization. Brain size scales with body weight between species within mammals to approximately the 0.67 power. However, within species, this scaling exponent appears to be much smaller (approximately 0.27 power). Aim: We examined whether this relationship has persisted in dogs over the 120 years since this was originally observed. Methods: Comparative cross-sectional study of magnetic resonance imaging (MRI) data obtained from 127 dogs, compared to historical data from 157 dogs and 24 non-dog canid species. Results: Brain size in dogs measured by MRI had a scaling exponent virtually identical to that observed previously (0.24 vs. 0.26). However, the proportionality constant was smaller, suggesting that dogs in the study cohort had relatively smaller brains than the historical cohort. Absolute brain size appeared to have both a lower and upper limit in dogs. When compared to non-dogs canids, the most appropriate “representative” size for a “typical dog” when examining allometric scaling across Canidae appeared to be approximately 10–15 kg. Conclusions: We interpreted the slight reduction in relative brain size to be a function of increased obesity in the study cohort compared to dogs examined 120 years ago. Further, we suggest that dog brains have a finite lower size limit. Finally, concepts of encephalization should not be applied to dogs.
