“…The veterinarians who completed postmortem examination also disregarded the protozoan infections when the infection led to partial condemnation of the carcass due to the presence of liver abscesses from Entamoeba species infection which it has the ability to devour red blood cells by Erythrophagocytosis through the process of analyzing its plasma membrane (29,30). In the current study, the frequency of protozoan infections was lower than the normal range reported in other studies.…”

Gastrointestinal parasites, such as helminths and protozoa, are abundant parasitic agents of livestock, particularly ruminants. The current study aims to determine the prevalence rate of parasitic infections in large ruminate animals slaughtered in the mechanical abattoir in Alexandria governorate, Egypt. The prevalence was identified through the records of parasitic infections detected in the fecal matter of large ruminate animals in addition to the recorded postmortem examination findings. Three hundred sixty-four slaughtered large ruminant animals were selected, labeled, and subjected to fecal sampling and postmortem examination. Each fecal sample was tested by three different techniques; the formalin-ether concentration, Ziehl-Neelsen hot-stained, and saturated saline flotation to diagnose all parasite types. One hundred thirty positive cases (35.71%) were determined during the fecal sample examination, and 76 cases (20.87%) were found in postmortem examination. Formalin-ether processing of fecal samples yielded the highest number of pathogens; Entamoeba species were detected in 98 fecal samples (26.69%), and Fasciola species eggs were detected in 14 samples (3.84%). The postmortem examination revealed Fasciola hepatica and F. gigantica in 13 animals (3.57%), mixed lung and liver hydatid cysts in 32 animals (8.79%), whereas liver hydatid cysts only were identified in 15 animals (4.12%). Finally, Sarcocystosis infection was detected in 3.57%. In conclusion, the parasitic infections of large ruminant animals are a leading cause of pathogenicity in large animals, leading to economic losses. Prevention and control measures must be implemented by mechanical abattoirs according to the hazard analysis critical control point system.

“…Although continuous IBV cases are detectable in most of the broiler farms in Duhok province, there have been no reports on circulating IBV strains or genotyping of this virus in the area. RT-PCR and Nested PCR have been widely used in this concern due to their efficiency in the identification and genotyping of the isolated IBV and other infectious agents in the broiler and other animals (16)(17)(18)(19). Therefore, this study was aimed to genotype the collected positive samples to IBV in the broiler fields in Duhok province, in Iraq.…”

Infectious bronchitis disease is becoming the most challenging disease in broiler fields in Iraq. This disease leads to massive economic loss every round of production. Three vaccine strains H120, Ma5, and 4/91 are used to combat the disease during the production period while outbreaks occur continuously. This study aimed to investigates the prevalence and circulation of Mass and 4/91 IBV strains in the broiler fields in Duhok province which is the first record in the area. Positive samples were obtained from suspected flocks to this disease during 2018-2020. A specific region of S1 was amplified using specific pairs of primers. Genotyping was performed by nested PCR using specified primers for detecting both Mass and 4/91 strains. In the results, all of the positive flocks were infected with nephropathogenic strain 793/B or 4/91. Two of the positive flocks had an infection with both Mass and 4/91. These results indicate that more than one strain circulates in the area as well as shows the weakness of vaccines used in broiler fields.
