Surgical treatment of bovine nasal granuloma and an allergological exploration
AbstractNasal granuloma in cattle results from inflammation within, and attendant proliferation of, the nasal mucosa possibly in response to an allergic response. However, the relationship between nasal granuloma and allergies remains unclear. Furthermore, severe cases have a poor prognosis because there is currently no effective treatment. Herein, we report three cases of nasal granuloma with severe stertorous breathing that were treated surgically. We also conducted an allergological exploration. Following surgical removal clinical signs did not recur in two of the three cases; however, stertorous breathing persisted in ...

Molecular evidence of Bartonella spp. in tropical wild birds from the Brazilian Pantanal, the largest wetland in South America
AbstractDespite the worldwide occurrence of bartonellae in a broad range of mammal species, in which they usually cause a long-lasting erythrocytic bacteremia, few studies reportedBartonella spp. in avian hosts. The present work aimed to investigate the occurrence and molecular identity ofBartonella spp. infecting birds in the Pantanal wetland, central-western Brazil using a multigene approach. For this purpose, blood samples were collected from 517 individuals from 13 avian orders in the states of Mato Grosso and Mato Groso do Sul. DNA was extracted from avian blood and 500/517 (96.7%) samples were positive in a conventio...

Minimum anesthetic concentration of isoflurane and sevoflurane and cardiorespiratory effects of varying inspired oxygen fractions in Magellanic penguins (Spheniscus magellanicus)
AbstractThe aim of this study was to determine the minimum anesthetic concentration of isoflurane (MACISO) and sevoflurane (MACSEVO) and evaluate the cardiorespiratory changes induced by varying fractions of inspired oxygen (FiO2) in Magellanic penguins (Spheniscus magellanicus). Twenty adult penguins (3.53 ± 0.44 kg) of undetermined sex were used. Both MACISO (n = 9) and MACSEVO (n = 13) were established using an up-and-down design. Next, twelve mechanically ventilated penguins were maintained at 1 MACISO or 1 MACSEVO (n = 6 per group) with the FiO2 initially set at 1.0. Three FiO2 values (0.6, 0.4 and ...

Anaplasma capra: a new emerging tick-borne zoonotic pathogen
AbstractThe genusAnaplasma includesA. marginale, A. centrale, A. bovis, A. ovis, A. platys, andA. phagocytophilum transmitted by ticks, some of which are zoonotic and cause anaplasmosis in humans and animals. In 2012, a new species was discovered in goats in China. In 2015, the same agent was detected in humans in China, and it was provisionally namedAnaplasma capra, referring to 2012. The studies conducted to date have revealed the existence ofA. capra in humans, domestic animals, wild animals, and ticks from three different continents (Asia, Europe, and Africa). Phylogenetic analyses based ongltA andgroEL sequences show ...

Copper-oxide nanoparticles effects on goldfish (Carassius auratus): Lethal toxicity, haematological, and biochemical effects
This study aimed to evaluate the lethal toxicity thresholds of Copper Oxide Nanoparticles (CuO-NPs). The investigation focused on examining the sub-lethal toxicity effects of CuO-NPs on blood parameters, as well as their influence on the gill tissue and liver of goldfish (Carassius auratus). Goldfish were exposed to varying concentrations of CuO-NPs (10, 20, 30, 40, 60, 80, and 100 mg/L) for 96 h. The Probit software was employed to determine the LC50 (lethal concentration causing 50% fish mortality) by monitoring and documenting fish deaths at 24, 48, 72, and 96-hour intervals. Subsequently, sub-lethal concentrations o...

Assessing safety, efficacy and residue depletion in golden mahseer, Tor putitora (Hamilton, 1822): biochemical and physiological responses to graded concentrations of oxytetracycline dietary supplementation
AbstractThe safety and effectiveness of oxytetracycline can potentially manage bacterial infections in fish. This, in turn, might reduce the concerns related to its use in aquaculture and human consumption, such as toxicity, antimicrobial resistance, and other associated risks. The primary objective of this study was to assess how adding oxytetracycline dihydrate to the diet affects its effectiveness, safety, and the presence of residues inT. putitora.T. putitora fingerlings, subjected to experimental infection withAeromonas hydrophila at a concentration of 108 CFU mL− 1, received an oral administration of oxytetracycl...

The clinical importance and correlations of post-partum changes in the clinical findings, reproductive cyclicity, serum-milk oxidant/antioxidant parameters as a stress indicator in female dromedary camel (Camelus dromedarius) and their effect on milk palatability
AbstractDramatic metabolic changes during pregnancy and post-partum period resulted in alteration of the biochemical parameters in dromedary she-camels. The current study focused on assessment of stress indicators in post-partum dromedary she-camels on days 14, 28 and 42 post-calving through monitoring the clinical findings, serum steroid hormones, serum or milk oxidant/antioxidant indicators, and milk somatic cell count (SCC) status with reference to serum lipid profile changes. The study also stated several correlations between reproductive cyclicity parameters, stress biomarkers and serum-milk oxidant/antioxidant indica...

Assessing colostral and serum immunoglobulin G in alpacas using Brix refractometry and total serum protein
AbstractThe adequate transfer of passive immunity is a critical factor in neonatal development and survivability. Although well documented in the dairy and equine industries, the recognition of inadequate immunoglobulin transfer on-farm and its impact on the ability of alpaca cria to thrive is largely unknown. Colostrum samples were collected from female alpaca within 24 h of parturition by the owners and whole blood collected from cria by the investigators between 1 and 7 days of age. Direct IgG concentration of milk and serum was determined using radial immunodiffusion assay (RID) and was indirectly estimated using op...

Combined effects of hypoxia and ammonia-N exposure on the oxygen consumption, glucose metabolism and amino acid metabolism in hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatus♂)
This study evaluated the influence of hypoxia and ammonia-N co-exposure on oxygen consumption, glucose metabolism and amino acid metabolism in hybrid grouper. The results showed that elevated expression ofGLUT1,MCT1,PFK,HK andLDH were induced by co-exposure to hypoxia and ammonia. In addition, co-exposure to hypoxia and ammonia reduced the tolerance of hybrid grouper to ammonia-N. Furthermore, ammonia-N exposure caused an increase in oxygen consumption in hybrid grouper. After ammonia-N exposure for 96 h, 10 amino acids contents and activities of AST and ALT elevated in hybrid grouper muscle. The study revealed that comb...

Seroprevalence of trypanosomosis and associated risk factors in cattle from coast and amazonian provinces of Ecuador
AbstractTrypanosomosis is a tropical disease caused by various protozoan haemoparasites, which affects wild and domestic animals, the latter ones related to worldwide livestock production systems. Species such asTrypanosoma vivax andTrypanosoma evansi have been described using serological and molecular tools in several countries from South and Central America. However, Ecuador presents a relevant knowledge gap in the associated general epidemiology and risk factors of the disease. Therefore, the objective of this study was to determine the seroprevalence of trypanosomosis in cattle from different regions of Ecuador. 745 se...

Equine brucellosis in Iran: serological, bacteriological and molecular analysis
AbstractEquine brucellosis significantly impacts the health and functionality of horses, leading to complications such as bursitis infection, septic tenosynovitis, septic arthritis, and non-specific lameness resulting from joint infections. In the present study, we used the Rose Bengal plate agglutination test (RBPT), serum agglutination test (SAT), and the 2-mercaptoethanol (2-ME) assays to find equine brucellosis. From June 2018 to September 2022, 876 blood samples were randomly taken from apparently healthy racing horses in certain parts of Iran, such as Kerman, Isfahan, Tehran, Qom, and Kurdistan. DNA extraction was ca...
