Leydig cell density was evaluated quantitatively in bilateral testicular
biopsies from twenty male rats of two equal groups Gossypol treated and
control. The method utilized for this quantitation is based on the determination
of total number of Leydig cells, Leydig cell clusters and seminiferous tubules in
the entire histological section of each biopsy and the calculation of the following
indices: mean Leydig cells per seminiferous tubule, mean Leydig cell clusters
per seminiferous tubule and mean Leydig cells per cluster. A significant positive
correlation between Leydig cells per tubule and Leydig cell clusters per tubule
was demonstrated. The results of indices curve showed shifted all the curves to

This work aimed to study the pathological changes induced in the
urinary organs after infection with K.pneumoniae. Two laboratory female
animal species ,white rat&guinea pig ,were infected by two
routes,ascending (first group) and direct(intra renal-second group).
The infection was examined in different periods through the bacterial
culture of urine & kidney samples as well as the pathological changes
(gross&microscopic) were examined after post mortum.
The resultes of both groups showed a positive bacteriologic culture of
the urine & kidney samples concomitant with the gross and
histopathological changes of the kidneys which revealed different degrees
of inflammation between the two groups a

Fifty isolates of Vibrio cholerae obtained from different areas in Iraq from patients with acute secretory diarrhea were diagnosed serologically in central public health laboratory(CPHL), Two different methods were used for detection cholera toxin production ,the first based on the degradation of Nicotin Amide Adinine Dinucleotide( NAD) by Cholera toxin (CT). and the second was by detection CT gene by polymerase chain reaction (PCR).All Vibrio cholerae were cultured in alkaline peptone water, out of 50 isolates 46 (92%) were positive when we used NAD for the detection of cholera toxin(CT).Whereas all isolates gave positive results by PCR. From these data we conclude that the degradation of NAD by CT is simple and can be carried out in sm

Crimean-Congo hemorrhagic fever (CCHF) is a viral zoonotic disease with a high
mortality rate in humans. CCHF is caused by genus Nairovirus, in family of Bunyaviridae,
and is transmitted to humans through the bite of ticks Hyalomma spp or contact with blood or
tissues of CCHF patients or infected livestock.
The total numbers of positive patients to CCHF virus was 11 out of 44 suspected samples
were examined from eight provinces during the period from January to December 2010 . The
way of transmission is due to contact with blood and tissues of infected animals, and one
patient slaughtered sheep in his house. ELISA was used to detect Crimean-Congo
hemorrhagic fever (CCHF) virus-specific immunoglobulin M (IgM) in hu

This study was carried out to detect the Cryptosporidium spp in Karbala province, Iraq from. December 2019 to September 2020. Age, sex, and months interference with parasite prevalence were studied. A total of 100 fecal samples were collected from adults and young and from both sexes of human. Fecal samples were subjected to conventional methods (Flotation Methods by Sheather's sugar solution and stained with modified Ziehl-Neelsen) for parasite diagnosis. The result recorded that the infection rate of Cryptosporidium spp was 26%. The age group of 2-6 years had the highest infection rate comparing to other age groups ranged from 12-25 years yet was marginal significant (P<0.06). Regarding sex, there was no
