Molecular typing of Protoparvovirus carnivoran 1 in Egyptian cats diagnosed with feline panleukopenia.

Comp Immunol Microbiol Infect Dis

December 2024

Department of Internal Medicine and Infectious Diseases, Faculty of Veterinary Medicine, Cairo University, Giza 12211, Egypt. Electronic address:

Feline panleukopenia (FPL) in cats is caused by either feline parvovirus (FPV) or canine parvovirus (CPV-2), which belong to the same species "Protoparvovirus carnivoran 1". While FPV is widely recognized as the principal cause of FPL, CPV-2 has been detected at a higher rate than FPV in sick cats in a recent Egyptian study. To assess this conflict, the present study aimed to determine which Protoparvovirus carnivoran 1 is commonly associated with FPL in Egyptian cats.

Background: Reticuloendotheliosis virus (REV) is an oncogenic immunosuppressive retrovirus that infects different kinds of avian species; posing significant economic losses to the poultry industry worldwide.

Methods: In Egypt, there is an unidentified disease associated with the runting-stunting syndrome with neoplasia, suspected to be REV, that has been continuously monitored in several breeder flocks. To diagnose and analyze REV by cell cultures, enzyme-linked immunosorbent assay (ELISA), histopathological investigation, the polymerase chain reaction (PCR) test, and sequencing analysis, 200 blood samples, and 50 tissue specimens were collected.

Article Synopsis
  • Peste des Petits Ruminants (PPR) is a viral disease affecting primarily goats and sheep, with some controversy around its impact on atypical hosts like cattle, warranting investigation into its progression in both species.
  • The study involved 32 animals (16 goats and 16 cattle) inoculated with a specific PPR virus strain, leading to significant clinical differences: goats showed typical symptoms and earlier virus detection than cattle, which displayed milder signs.
  • Findings emphasize the need for further comparative pathology studies to enhance understanding of PPR virus dynamics and potential transmission pathways, which could be crucial for controlling outbreaks.

  • Bovine tuberculosis (bTB) is a disease affecting cattle, especially common in crossbred cows in Ethiopia, but there aren't enough checks to find it.
  • In a study, scientists checked over 7,640 cattle at slaughterhouses and found that only 2.3% had signs of bTB, with crossbred cows being at higher risk.
  • Most of the sick cattle had problems in their lungs or lymph nodes, and tests confirmed that M. bovis, a type of bacteria, was responsible for the infections.

  • Peste des petits ruminant (PPR) is a contagious disease affecting sheep and goats in Ethiopia, posing a serious economic threat to the pastoral production system; a study in the Borena Zone assessed the prevalence and risk factors associated with the virus.
  • Out of 384 serum samples tested, seroprevalence was noted at 32.1% for nonvaccinated, 68.8% for vaccinated, and 45.5% for those with unknown vaccination status; age, origin, flock size, and veterinary services were identified as significant risk factors.
  • The findings revealed critical weaknesses in vaccination efforts, with herd immunity below the recommended 80% threshold, indicating that Ethiopia's strategy for eradicating

Department of Biomedical Sciences-Physiology, Faculty of Veterinary Medicine, Animal Health Institute (INDEGSAL), Campus de Vegazana, Universidad de León, 24071 León, Spain.

The ABCG2 membrane transporter affects bioavailability and milk secretion of xenobiotics and natural compounds, including vitamins such as riboflavin. We aimed to characterize the in vitro and in vivo interaction of ABCG2 with lumichrome, the main photodegradation product of riboflavin, which has proven in vitro anti-cancer activity and a therapeutical role in antibacterial photodynamic therapy as an efficient photosensitizer. Using MDCK-II polarized cells overexpressing murine Abcg2 and human ABCG2 we found that lumichrome was efficiently transported by both variants.

Importance: Alzheimer's disease (AD) is the most common cause of dementia in the elderly with the incidence rising exponentially after the age of 65 years. Unfortunately, effective treatments are extremely limited and definite diagnosis can only be made at autopsy. This is in part due to our limited understanding of the complex pathophysiology, including the various genetic, environmental, and metabolic contributing factors.

Background: Q fever is a worldwide occurring neglected zoonotic disease with great economic importance. The etiological agent, is a bacterium usually associated with subclinical infections in livestock, but may also cause reproductive pathology and spontaneous abortions in artiodactyl species including goats, sheep and cattle which are deemed to be the primary reservoirs of this disease.

Aims: The present cross-sectional and questionnaire survey was undertaken in three districts of the South Omo zone with the aims to comprehend the community perception of livestock keepers and professionals about the disease, estimate the seroprevalence of () in cattle and small ruminants and to determine the species of potential tick vectors of infesting cattle, sheep and goats.

  • Peste des petits ruminants virus (PPRV) primarily affects sheep and goats, but this study examined the potential role of cattle in spreading the virus.
  • Despite co-housing Zebu cattle with goats and infecting the cattle with PPRV, there was no transmission to the goats, confirming that cattle have a minimal role in PPRV spread.
  • The study supports the idea that vaccinating small ruminants is enough for eradication, but warns that more virulent PPRV strains could emerge in cattle, highlighting the need for ongoing monitoring.
