The status of tuberculosis in Sudanese goats and sheep has not been studied yet; hence this study was designed to investigate the prevalence and pathological characteristics of tuberculosis in small ruminants in South Darfur State during the period October 2015 to February 2017. Slaughtered goats (3200) and sheep (3260) were examined for pathological tubercle lesions and histopathological changes. Grossly, tubercle like lesions which appearance as embedded in the parenchyma or bulging on surface of organs and tissues in variable sizes with white colour were observed in 119 (3.72%) goats and 93 (2.85%) sheep. Histopathological examination showed central caseous necrosis with or without calcified areas surrounded by epithelioid cells and langhan's giant cells with fibrous capsule infiltrated by lymphocytes and plasma cells with or without scattered acid fast bacilli in the granulomatous regions. Our findings indicate that presence of tuberculosis in the Sudanese goats and sheep, and Ambboror sheep and Baggara goats were the reservoirs of tuberculosis among the livestock in the region and and respiratory pathway was the most site of infection in goats and sheep. Therefore, proper implementation of meat inspection procedures at abattoir with public awareness are important to control tuberculosis in South Darfur State. In addition, large scale surveillance is needed in different parts of the Sudan to estimate the apparent and true prevalence of tuberculosis among animals and animal workers

Genotypes grown under Saline and non - Saline ConditionsHamza, Fatih E.A.Elhashimi, Ashraf M.

Genotypes grown under Saline and non - Saline Conditions
Hamza, Fatih E.A.; Elhashimi, Ashraf M. A.
A field experiment was conducted during three consecutive
winter seasons of the years 2008/09, 2009/10 and 2010/11 at
Merowe Research Station Farm, Northern State, Sudan to
estimate the genetic variability, heritability and genetic advance
of grain yield and yield contributing traits in 16 bread wheat
genotypes grown under saline and non – saline field conditions.
The genotypes were arranged in a randomized complete block
design with three replications. In both sites, the analysis of
variance revealed highly significant differences among
genotypes for all the traits studied. The phenotypic coefficient
of variation (PCV) was higher than the genotypic coefficient of
variation (GCV), which indicates a slight effect of environment
on the expression of the characters studied. In both sites, high
genotypic coefficient of variation (GCV) and phenotypic
coefficient of variation (PCV) were recorded for number of
spikes per m2, plant height and number of grains per spike. In
both sites, heritability exhibited wide range of variation. At non
– saline site, the high heritability in broad sense was estimated
for number of days to 50% heading (87.03), number of days to
90% maturity (85.13), plant height (83.79), 1000 – grain weight
(62.78) and number of spikes per m2 (58.87). On the other
hand, at saline site high heritability estimates were recorded for
number of days to 90% maturity (85.16) followed by number of
days to 50% heading (84.29) and plant height (53.11). These
traits also indicated high genetic advance except the plant
height. In both sites, high heritability coupled with high genetic
advance as percent of means were recorded for number of days
to 50% heading, number of days to 90% maturity and plant
height that indicated presence of additive gene action in the
inheritance of these traits.

Osman, Aisha Mohammed; Ahmed, Asma A.; Bakhiet, Amel O.
The aim of the present study was to evaluate the safety of
living nearby cell phone towers which emit Radio Frequency-
Electromagnetic Radiation (RF-EMR) through in vivo study and what is
the risk of these radiations on fertility hormones (FSH, LH and PRL) and
histopathological changes of testes of Wistar male rats. A 28 days old
male rats 35 - 54.2 g of body weight, were used. Rats were exposed to RFEMR
emitted by cell tower base station in Khartoum State. The rats were
divided into four different groups. Control animals that were kept without
exposure to any RF-EMR. The rats were in the other three groups exposed
for 8 weeks to RF-EMR at: 57nw/m2, 37nw/ m2, and 10nw/m2. The
exposure to radiation was on daily basis for 10 hours at temperature 30–
33ºC. Fertility hormones viz: FSH, LH and PRL were estimated. Exposure
to RF-EMR caused significant decrease in the weight of testes of
experimental rats in all groups. Also had significant increase effects on
PRL however there was significant decrease in FSH and LH in all groups
of rats exposed RF-EMR when compared with the control group.
Histopathological examination of testes among groups exposed to RFEMR
showed various changes. Most seminiferous tubules of testis of male
rats exposed to RF-EMR (57nw/m2) showed polymorphism, necrosis in
the germinal epithelial cells, hypertrophy and degeneration of
spermatogonia cells, interstitaial oedema, and absence of sperm. While
those exposed to RF-EMR (37nw/m2) showed deceleration of
spermatogemesis, vaculation of leyding cells, started atrophy of
spermatids cells and haemorrhages. Sections of testis of male rats exposed
RF-EMR (10nw/m2) showed shrinking of some seminiferous, oedema,
hyperplasia and vaculation of spermatocytes, blood vessels dilated,
fibrosis of tunica, fusion between some seminiferous tubules. It could be
concluded that exposure to RF-EMR emitted from cell tower does
represent a significant risk factor for rat reproductive system

A., Shehab M.; Abdalla, M.A.; Suliman, Siham E.
This study was conducted in Animal House veterinary
Hospital Salymia region, Kuwait state. The study focuses
on the domestic cats because it is very important in
public health . The majority of families in Kuwait have
domestic cats and other pets in their homes. Fecal
samples were collected monthly at random from
domestic cats in different age, sex and breed that visited
the Hospital at the rate of 10 to 15 faecal samples per
month. A questionnaire was prepared and completed by
the owners of cats included in this study .Direct
centrifugal flotation technique was used for the detection
of internal parasites, their larval stages and eggs
.External parasites were examined by comb counting
examination of fur and ear smears .The study extended
over a year from November 2014 up to November 2015.
Among 150 cats surveyed, 27 cats (18%) had Otodectes
cynotis; 33 cats had Ancylostoma tubaeforme (22%) and
11 cats (7.3%) were infected with Isospora felis. Routine
examination and regular deworming were suggested for
protection of cats breeds in Kuwait.
