Objective: To report and compare the hematological and serum biochemical profile of goat and sheep from Rahim Yar Khan district in Southern Punjab. Methods: One hundred and twenty blood samples (98 goat and 22 sheep) were collected and their blood glucose, hemoglobin and serum biochemical parameters, cholesterol, aspartate transaminase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were determined by using spectrophotometer. Parameters were compared between goat and sheep. Results: It was observed that glucose (P=0.001), LDH (P=0.001) and ALT (P=0.001) concentrations differed significantly between sheep and goats. The studied parameters were compared between buck and goats and also between young goats (less than 12 months old) and adults (more than 12 months old). It was found that age and gender did not affect these hematological and serum biochemical parameters.Conclusions: It can be concluded that sheep have overall higher values than goats for studied hematological and serum biochemical parameters.

OBJECTIVETo determine the presence of Babesia bovis (B. bovis) in large ruminants in southern Punjab and its effect on hematological and serum biochemical profile of host animals.

METHODSBlood samples were collected from 144 large ruminants, including 105 cattle and 39 buffaloes, from six districts in southern Punjab including Multan, Layyah, Muzaffar Garh, Bhakar, Bahawalnagar and Vehari. Data on the characteristics of animals and herds were collected through questionnaires. Different blood (hemoglobin, glucose) and serum (ALT, AST, LDH, cholesterol) parameters of calves and cattle were measured and compared between parasite positive and negative samples to demonstrate the effect of B. bovis on the blood and serological profile of infected animals.

RESULTS27 out of 144 animals, from 5 out of 6 sampling districts, produced the 541-bp fragment specific for B. bovis. Age of animals (P=0.02), presence of ticks on animals (P=0.04) and presence of ticks on dogs associated with herds (P=0.5) were among the major risk factors involved in the spread of bovine babesiosis in the study area. ALT concentrations were the only serum biochemical values that significantly varied between parasite positive and negative cattle.

CONCLUSIONS: This study has reported for the first time the presence of B. bovis in large ruminant and the results can lead to the prevention of babesiosis in the region to increase the livestock output.

Exploring the genetic basis of human infertility is currently under intensive investigation.However,only a handful of genes have been validated in animal models as disease-causing genes in infertile men.Thus,to better understand the genetic basis of human spermatogenesis and bridge the knowledge gap between humans and other animal species,we construct the FertilityOnline,a data-base integrating the literature-curated functional genes during spermatogenesis into an existing sper-matogenic database,SpermatogenesisOnline 1.0.Additional features,including the functional annotation and genetic variants of human genes,are also incorporated into FertilityOnline.By searching this database,users can browse the functional genes involved in spermatogenesis and instantly narrow down the number of candidates of genetic mutations underlying male infertility in a user-friendly web interface.Clinical application of this database was exampled by the identifi-cation of novel causative mutations in synaptonemal complex central element protein 1(SYCE1)and stromal antigen 3(STAG3)in azoospermic men.In conclusion,FertilityOnline is not only an integrated resource for spermatogenic genes but also a useful tool facilitating the exploration of the genetic basis of male infertility.

Meiosis is an essential step in gametogenesis which is the key process in sexually reproducing organisms as meiotic aberrations may result in infertility. In meiosis, programmed DNA double-strand break (DSB) formation is one of the fundamental processes that are essential for maintaining homolog interactions and correcting segregation of chromosomes. Although the number and distribution of meiotic DSBs are tightly regulated, still abnormalities in DSB formation are known to cause meiotic arrest and infertility. This review is a detailed account of molecular bases of meiotic DSB formation, its evolutionary conservation, and variations in different species. We further reviewed the mutations of DSB formation genes in association with human infertility and also proposed the future directions and strategies about the study of meiotic DSB formation.
