Abstract
Campylobacter jejuni (C. jejuni) is a common pathogen that often causes diarrhea, loss of appetite, and even enteritis in domestic cats, affecting their growth and development, especially in kittens under 6 months of age. Oral passive immunization with chicken yolk antibody Y has been proved effective for the treatment of gastrointestinal pathogen infections due to its high specificity. In this study, C. jejuni was isolated from diarrheal cat feces, and the specific egg yolk antibody Y against C. jejuni was demonstrated to effectively inhibit its proliferation in vitro experiments. To evaluate the effect of anti-C. jejuni IgY, the mouse C. jejuni infection model was established and it was found that IgY could alleviate C. jejuni-induced clinical symptoms. Consistent with these results, the reduction of pro-inflammatory factors and intestinal colonization by C. jejuni in the IgY-treated groups, especially in the high dose group. We then evaluated the protective effect of IgY on young Ragdoll cats infected with C. jejuni. This specific antibody reduced the rate of feline diarrhea, protected the growth of young cats, inhibited systemic inflammatory hyperactivation, and increased fecal short-chain fatty acid concentrations. Notably, IgY may have a protective role by changing intestinal amino acid metabolism and affecting C. jejuni chemotaxis. Collectively, specific IgY is a promising therapeutic strategy for C. jejuni-induced cat diarrhea.

Abstract
N-acylhydrazones are considered privileged structures in medicinal chemistry, being part of antimicrobial compounds (for example). In this study we show the activity of N-acylhydrazone compounds, namely AH1, AH2, AH4, AH5 in in vitro tests against the chloroquine-resistant strain of Plasmodium falciparum (W2) and against WI26 VA-4 human cell lines. All compounds showed low cytotoxicity (LC50 > 100 µM). The AH5 compound was the most active against Plasmodium falciparum, with an IC50 value of 0.07 μM. AH4 and AH5 were selected among the tested compounds for molecular docking calculations to elucidate possible targets involved in their mechanism of action and the SwissADME analysis to predict their pharmacokinetic profile. The AH5 compound showed affinity for 12 targets with low selectivity, while the AH4 compound had greater affinity for only one target (3PHC). These compounds met Lipinski's standards in the ADME in silico tests, indicating good bioavailability results. These results demonstrate that these N-acylhydrazone compounds are good candidates for future preclinical studies against malaria.

Abstract
Immunoglobulin yolk (IgY) is therapeutic antibodies presented in yolk eggs of birds, reptiles, and amphibians. These proteins produced by the immune system of the animal, are capable of neutralizing antigenic molecules, including viral antigens, fulfilling a role in the body defense. The specificity of these antibodies and the facility for their production, make these molecules capable of being used as tools for diagnosis and immunotherapy. Regarding this last aspect, it is common knowledge that the field of virology, is racing against time in the development of new drugs and vaccines to try to contain pandemics and local epidemics and, in counterproposal, avian antibodies are neutralizing molecules that can help in the control and spread of disease. These molecules have been explored for years and currently chicken eggs are produced in large quantities from the animal's immunization against a specific pathogen. Thus, on this subject, this review made a survey of these researches and presents a summary of all the successful cases and perspectives in the use of IgYs as tools for viral immunization.

Abstract
La aparición de microorganismos resistentes a antibióticos, el descubrimiento de nuevos agentes patógenos con potencial pandémico y el aumento de una población inmunocomprometida han dejado casi obsoleta la terapia antimicrobiana, terapia comúnmente usada para tratar enfermedades infecciosas. Por otro lado, las investigaciones acerca del uso del anticuerpo IgY para desarrollar inmunidad pasiva han demostrado el potencial que tiene la tecnología IgY para tratar enfermedades infecciosas víricas y bacterianas. Donde los anticuerpos IgY de aves se destacan por su alta especificidad, rendimiento y escalabilidad de producción a menor costo, con relación a los anticuerpos IgG de mamíferos. El objetivo de esta revisión es determinar la importancia del uso de los anticuerpos IgY como tratamiento terapéutico y profiláctico frente a los patógenos causantes de infecciones virales y bacterianas en humanos, mediante la recopilación de ensayos clínicos, productos comerciales y patentes registradas en el período de 2010-2021. Finalmente, con este estudio se estableció que la tecnología IgY es una herramienta biotecnológica versátil y eficaz para tratar y prevenir enfermedades infecciosas, al reducir los síntomas y la carga del patógeno.

Abstract
Egg yolk constitutes a relevant alternative source of antibodies. It presents some advantages over mammalian serum immunoglobulins regarding productivity, animal welfare and specificity. The main immunoglobulin present in avian blood (IgY) is transmitted to their offspring and accumulates in egg yolks, which enables the non-invasive harvesting of high amounts of antibodies. Moreover, due to structural differences and phylogenetic distance, IgY is more suitable for diagnostic purposes than mammalian antibodies, since it does not react with certain components of the human immune system and displays greater avidity for mammalian conserved proteins. IgY has been extensively used in health researches, as both therapeutic and diagnostic tool. This article aims to review its applications in both human and veterinary health.

Abstract
Due to the epidemiological problem of the neglected condition of human strongyloidiasis, rapid and effective diagnosis is extremely important, with the development of new diagnostic tools being essential to reduce infections and chronic cases. Avian immunoglobulin Y (IgY) technology is an alternative for antibody production that has high specificity and profitability. This study aimed to produce and fractionate IgY antibodies from the egg yolks of hens that were immunized with the total antigenic extracts of Strongyloides venezuelensis infectious filariform larvae (iL3) and parthenogenetic females (pF). IgY antibodies were then evaluated by their recognition of antigenic proteins, evolutive helminth forms, and serological diagnosis of human strongyloidiasis by the detection of immune complexes in serum samples. Egg yolks were fractionated to obtain IgY antibodies by thiophilic interaction chromatography. Immune complex detection in serum samples showed diagnostic values for anti-iL3 IgY and anti-pF IgY antibodies at 95.56% and 88.89% sensitivity and 95.56% and 91.11% specificity, respectively. Therefore, IgY technology is a promising tool for the detection of blood circulating Strongyloides antigens, with possible application as a serological diagnostic method.

Abstract
Human enterovirus 71 (EV71) is one of the major pathogens that causes hand-foot-and mouth disease, and there is an urgent need for rapid diagnosis of EV71 virus infection for early antiviral treatment. The aim of this study was to prepare chicken egg yolk immunoglobulin Y (IgY) for the diagnosis of enterovirus type 71 infection. The antibodies were raised by intramuscular immunization of laying hens with inactivated human EV71 and isolated from the egg yolk by multiple steps of polyethylene glycol 6000 extraction. The average concentration of IgY antibody was 26.60 mg/mL during the whole immunization. After the first immunization, the IgY titer gradually increased, and reached the peak on the 55th days. Meanwhile, the use of western blotting test demonstrated that specific IgY binds specifically to capsid proteins VP2 and VP3 of EV71 virus. Furthermore, a facile one-step method based on turn-on fluorescence sensing was developed by using IgY antibodies, which can detect EV71 virus at low concentrations of 104 PFU/mL and was 94.44% coincidence with RT-PCR in 30 clinical samples. These findings indicate that EV71-IgY antibodies are an easily prepared and rich source of antibodies that offers a potential alternative strategy for routine screening of EV71 infection.

Abstract
Conjugation of avian IgY antibodies to nanosensors has been extensively explored for the diagnostics of virus and parasite infection, as well as for the detection of pharmaceutically and toxicologically relevant molecules. However, to date this strategy has only been minimally applied the detection of allergens. In this study, gold nanoparticles (GNPs) were conjugated to a polyvalent IgY antibodies raised against Dermatophagoides group I allergens. GNPs were synthesized by HAuCL4 reduction using 1% trisodium citrate, and characterized them by absorption spectroscopy and transmission electron microscopy (TEM). The most stable immunoconjugates were obtained with 18-nm monodisperse GNPs and a minimal concentration of 12.5 μg/mL of IgY at pH 7.5. The immunoconjugate was capable of detecting up to 1.5 μg of a total Dermatophagoides farinae protein extract in an immuno-dot blot assay. This immunoreactant conjugate represents a new tool for the detection and control of indoor dust mite allergens.
