Background & Aims: The H9N2 avian influenza subtype is endemic in many parts of Iran and has the ability to transmit from bird to human. In the present study, the risk of this subtype for humans was assessed by determination of the viral titer and shedding time in bird. Method: The experiment was done on fifteen male budgerigars at 4 months of age. The birds w...

BACKGROUND Early studies in dabbling ducks showed that cloacal swabs yielded a larger number of avian influenza virus (AIV) isolates than did respiratory tract swabs. Historically, AIV surveillance has been performed by collecting cloacal or environmental fecal samples only. Highly pathogenic avian influenza H5N1 virus emerged in 1996 and replicated to higher titers in the respiratory rather th...

In birds, microparasites found in both the reproductive and the digestive tracts may be transmitted through copulations via cloacal contact (male-to-female and vice versa) and/or through the seminal fluid (mainly male-to-female). Most importantly, such cloacal microparasites are affected by and may in turn affect sexual selection processes and the evolution of mating systems. Here I provide pre...

BACKGROUND Cloacal malformation is a spectrum of diseases affecting females, resulting in abnormal confluence of the urinary system, genital system, and/or gastrointestinal system. Proper reconstruction depends mainly on accurate preoperative illustration of the abnormal anatomy. Among the various modalities to delineate the urogenital sinus and the distances to confluence, lies the radiologica...

The cloacal gland is a paired exocrine structure, which has so far been described only in the formicine species, Camponotus ephippium and Cataglyphis savignyi (Hymenoptera : Formicidae). The gland is formed by 2 clusters of bicellular units with slender duct cells, releasing the glandular secretion through the cloacal membrane. In the present work, a number of ant species, largely of the Formic...

introduction: cloacal malformation is an extremely rare fetal pathological condition but an important anomaly that presents as a variety of defects. it predominantly affects females, with prevalence of 1 in 50,000 births. prenatal ultrasonography usually showed oligohydramnios and the fetus having a large cystic mass in the lower abdomen with a single septum, bilateral hydronephrosis, ambiguous...

Cloacal exstrophy is a very rare and complex malformation. We report a neonate of cloacal exstrophy with mature teratoma presenting as a component of exstrophy. To our knowledge this has not been reported in the literature.

Background: Women with repaired bladder/cloacal exstrophy face unique challenges throughout their pregnancy. Limited obstetric care information available in the current literature. Aims: To review perinatal issues, pregnancy outcomes and surgical techniques for five pregnancies in three women with repaired bladder exstrophy and cloacal exstrophy. Materials and Method Design: A case series and r...

Cloacae were examined from male and female salamanders representing 12 genera and 22 species in the Salamandridae. All female salamandrids possess numerous sperm storage glands, spermathecae, in the roof of the cloaca, but intergeneric variation exists in the occurrence of additional cloacal glands. Pleurodeles and Tylototriton possess both vent and anterior ventral glands, and secondary loss h...
