The objective of this review article was to discuss the interaction between virus effectiveness and host immune system challenges on the innate and adaptive on how the immune system able to defend against COVID-19 viral infections. Genetically, the COVID-19 is a virus that has genetic material coated by lipid with a crown of protein. The virus that causes COVID-19 is called severe acute respiratory syndrome coronavirus two (SARS-COV-2) and was first detected in humans last December 2019. Primarily, the COVID-19 virus spreads with droplets of saliva or nose discharge when an infected person sneezes or coughs. Most people with a healthy immune system those infected with the COVID-19 virus showed mild to moderat

The prevalence of ostrich’s cryptosporidiosis was determined for the first time in central and south parts of Iraq to study the effects of age, sex, and months on the infection rate and to record the morphological characterization of Cryptosporidium spp in ostriches. A total of 200 ostriches fecal samples were examined by traditional methods for the detection of the parasite. The total infection rate was 11% (22/200), and the highest infection rate was 12.26% (13/106) in chicks ( 9 months), while the lowest infection rate was 9.57% (9/94) recorded in the adult (> 9 months). The study included seven provinces in the central and south parts of Iraq, Wasit, Baghdad, Babylon, Diyala, Karbala, Al-Najaf, an

A total of 300 one day old unsexed broiler chicks were divided into three
dietary groups which were: -
T1: Un-treated control.
T2: Poultrygrow 250 treated group.
T3: Cr-Yeast treated group.
Results have shown that the addition of Poultrygrow 250 and Cr-Yeast
have significantly (p < 0.05) improved the performance of broilers express in
weight gain and feed conversion ratio compared with control group. The study
showed an increase in red blood cell and hemoglobin and reduce in hetrophil /
Lymphocyte ratio.It was concluded that the supplementation of poultrygrow 250
and Cr-Yeast in the diet of broiler chickens could improve the performance of
the birds.

Ruminal acidosis was induced experimentally in local bucks fed on
AL-zahdy dates at 20 and 40 g/kg B.W. daily. Two groups of five animals
each beside another group of five animals as a control reseved 20g/kg B.W.
of concentrates beside green roughage. One animal from each group was
surgically provided with ruminal fistula. The experiments lasted for four
weeks during which the animals examined clinically daily, and ruminal fluid
and blood samples were collected weekly.The results showed that the
animals in the two experimental groups show significant rise in the means of
respiratory and pulse rates,but not in body temperature.The ruminal
contractions ranged between weak and reduced in the 1st experiment to

Bovine anaplasmosis is one of the tick-borne diseases caused by Anaplasma marginale bacteria which can cause high economic losses to livestock. Cattle that recovered from acute infection become carriers without clinical signs related to the disease and these bacteria can persist for lifetime in the blood. The present study was conducted to detect antibodies of persistently infected cattle with A. marginale in Wasit province/ Iraq. A total of 100 blood samples were collected randomly from cattle over one year old. Blood smears were prepared, stained with Giemsa,s stain and subjected to microscopic examination for detection of Anaplasma marginale bacteria within an infected RBCs, while serum samples were tested by a competitive enzyme - li

The aim of this study was to investigate the effect of using milled Zingiber
Rhizome and vitamin E on some reproductivity traits (serum hormones levels, SSH and
testosterone and semen characters).
Eighteen Iraqi Black kids at age of 5-6 months were bought and divided into
three groups equally (body weight was considered), each group contained 6 kids. This
study was carried out in Animal's Farm, College of Veterinary Medicine, University of
Baghdad from 1st November 2007 up to end of May 2008, and treated as followed:
The first group (Z) (Zingiber group) was fed on concentrates diet (400 g/head)
daily which contained 10 g of zingiber (2.5% of diet). The second group (Z+E)
(Zingiber group + vit. E) was given the

Eighteen rats were divided into three equal groups. The first group was closed orally with quassin, the second group was dosed with quassin after the gut flora were suppressed by difierent antibiotics, and the third group was served as a control. Food intake, water intake, and change in body weight were measured daily before dosing, during two weeks of dosing, and during one week after stopping dosing. Two eats from each group were killed at the end of each week, and stomach, liver, and kidney were collected for histopathologic examination.

The results show a significant decline in daily food intake and daily change in body weight, and a significant increase in daily water intake in both dosed groups during the dosing period
