The adverse side effects of prenatal and postnatal rats' exposure to silver nanoparticles Induced toxicity.

Background: Silver nanotechnology is widely applied in industry and medicine, with an increased likelihood of environmental and food contamination.

Aim: This study aimed to explore the adverse effects of orally administering silver nanoparticles (AgNPs) to pregnant or lactating female rats on adults and the development of their offspring.

Methods: Forty female albino rats were used to assess the immediate impacts of AgNPs in two separate experiments.

Serosurvey and associated risk factors for Chlamydia abortus infection in Dromedary camels in Egypt.

Chlamydia abortus (C. abortus) is a gram-negative, obligate intracellular bacterium that causes major public health problems in human and reproductive problems in animals. The information about the epidemiology of this pathogen among camels in Egypt is very rare.

Seroprevalence and associated risk factors for bovine leptospirosis in Egypt.

Leptospirosis is caused by pathogenic bacteria of the genus Leptospira and is one of causative agents of reproductive problems leading to negative economic impact on bovine worldwide. The goal of this study was to investigate the seroprevalence of Leptospira spp. in cattle in some governorates of Egypt's Nile Delta and assess the risk factors for infection.

Serosurvey and associated risk factors for Chlamydia abortus infection in cattle from Egypt.

Chlamydia abortus is an important gram-negative pathogen poses serious public health problem in human and reproductive disorders in animals. There are very few data on the prevalence of C. abortus in cattle and none on the associated risk factors for infection in cattle in earlier literature.

Scanning Electron Microscopic Findings on Respiratory Organs of Some Naturally Infected Dromedary Camels with the Lineage-B of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) in Saudi Arabia-2018.

The currently known animal reservoir for MERS-CoV is the dromedary camel. The clinical pattern of the MERS-CoV field infection in dromedary camels is not yet fully studied well. Some pathological changes and the detection of the MERS-CoV antigens by immunohistochemistry have been recently reported.
