Summary: An outbreak of cat vomiting in an animal shelter was found to be associated with feline astrovirus infection, which was detected in cases as well as controls through viral metagenomics. The study revealed significant asymptomatic shedding of astrovirus in affected and unaffected cats, indicating the virus's role in the contagious outbreak.

Summary: This study analyzed the metabolic characteristics of breeding pigeons during lactation and found that male pigeons undergo catabolism and exhibit slower body weight recovery compared to female pigeons. Female pigeons experience the highest weight loss on the seventh day and gradually recover their body weight. Female pigeons also have higher oxidative stress levels and increased blood lipid indexes and hormone levels during lactation. These findings provide important information for precision feeding and improved breeding of pigeons.

Summary: This study investigated the composition and changes in crop milk protein of squabs using proteomic techniques. The results showed that crude protein contents in crop milk decreased with age, and a total of 2558 proteins were identified with significant differences between different stages. The differential expressed proteins were mainly related to protein synthesis, immunity, and antioxidation, providing valuable information for future development of artificial squab milk products.

Summary: In this study, an outbreak of Newcastle disease virus (NDV) in pigeons in Northeastern Brazil in 2018 was investigated. The affected pigeons exhibited neurological signs and were confirmed positive for NDV through rRT-PCR and virus isolation. Next-generation sequencing was conducted to characterize the isolated NDV strain. The findings emphasize the importance of virus surveillance in wild and domestic birds, particularly the zoonotic risk associated with NDV.

Summary: The study found significantly reduced septum activation during spatial learning in older pigeons, but no significant change in NDB activation. Additionally, older pigeons had substantially fewer ChAT-expressing cells in the septum compared to younger pigeons, supporting the hypothesis that reduced septum activation contributes to age-related spatial cognitive impairment in pigeons.

Summary: Research found that as pigeons age, their memory capacity decreases, but not all aged pigeons show cognitive impairments. In the task, pigeons' understanding of the sequence of items shows stability over age, unlike memory capacity.

Summary: During 2014-2018, the annual number of HIV diagnoses made by the ED program increased from 20 to 42 overall, with the ED contributing 18% of HIV diagnoses in the county and 22% of diagnoses among PWID. The study highlights the importance of ED HIV screening programs in identifying undiagnosed HIV infections among PWID during an HIV outbreak.

Summary: The potential costs associated with dominance were studied in two flocks of domestic Homing Pigeons, where the most dominant birds within the flocks were found to have significantly higher movement levels than others. This suggests a possible cost to possessing the top rank within a dominance hierarchy.

Summary: This study evaluated the occurrence of PPMV-1 in confinement-reared pigeons in California, characterized PPMV-1 isolates from diagnostic cases, assessed the disease presentation, and identified epidemiological trends based on pigeon cases submitted to the CAHFS laboratory system. PPMV-1 was diagnosed in 23% of the accessions, with the highest percentage of cases occurring in 2014. Trichomoniasis and colibacillosis were the most common comorbidities in squab and racing/show pigeons, respectively. Phylogenetic analysis revealed sequence similarities and unique clades among the PPMV-1 isolates.

Summary: The study confirmed porcine SaV GIII as the sole cause of enteritis and diarrhea in pigs and established a reliable detection method. Pigs with clinical diarrhea had significantly higher viral loads than clinically healthy pigs, and intragenogroup recombination was found in field isolates of SaV GIII.

Summary: This study evaluated the risk of positive dengue viral (DENV) RNA from blood transfusions during a large outbreak in Taiwan. Approximately 0.5%-1% of blood donations were DENV RNA positive in epidemic districts, and the correlation of DENV RNA rates with dengue incidence may inform the design of effective control measures. The detection rate of DENV RNA increased with rising local incidence in a nonendemic country, suggesting the need for mitigation polices and active surveillance during serious outbreaks.

Summary: This study aimed to characterize the antimicrobial resistance of Escherichia coli isolated from free-living urban pigeons in South Brazil. The results revealed that these pigeons carry multidrug-resistant pathogenic E. coli and some resistance genes. This poses potential risks to public health.

Summary: The PCR-RFLP molecular assay was verified as a convenient technique for detecting the MS-H vaccine strain, and the immune response mechanisms in vaccinated layer-type chickens were characterized. Vaccination stimulated immune response mechanisms in chickens with no significant difference between single and double doses.

Summary: Chicken in southern Thailand has different prevalence and resistance patterns of Campylobacter. Commercial broilers exhibit higher resistance to quinolones and lower resistance to macrolides and tetracycline compared to native chickens. Resistance patterns are more consistent within farms, and commercial broilers show higher homogeneity. Phenotypic and genotypic resistance have partial agreement among isolates.

Summary: This study evaluated the relative efficacy of allopurinol and febuxostat, two important anti-gout agents, in controlling hyperuricemia/gout using a poultry model. The results showed that both allopurinol and febuxostat have definite potential for ameliorating hyperuricemia and gout in poultry, with febuxostat showing better effects compared to allopurinol.

Summary: This report describes an outbreak of Salmonella Pullorum (SP) in a Dutch laying flock, causing increased mortality, decreased egg production, and neurological signs. SP was frequently isolated from various organs, and immunostaining showed cerebral granulomas in birds with neurological signs. Vaccination did not affect the detection of SP antibodies. Some clinically healthy birds had ovarian lesions associated with SP contact, but carrier status could not be confirmed. Phylogenetic analysis showed clonality of the SP isolates within the outbreak.

Summary: This study investigates the regulation of miR-33-5p gene expression during MG infection. The researchers found an upregulation in pri-miR-33-5p and pre-miR-33-5p expression, indicating transcriptional regulation. They identified a binding motif for STAT5 in the miR-33-5p promoter element and showed that STAT5 modulates miR-33-5p transcription in response to MG infection. The overexpression of STAT5 led to increased miR-33-5p expression while suppressing JNK1 expression.
