“…It is known that only seropositivity does not certainly associate with abortion in all conditions. It is important to identify the actual causes in the aborting sheep and goats and/ or in the aborted fetus or placental tissues to confirm the pathogen is accountable for abortion (Morris et al, 2018). This result is in line with the reports of Gebremedhin (2015) and Wubishet et al (2017), who reported that the risk of Brucella seropositivity was not associated with abortion.…”

The occurrence of brucellosis in different species of livestock has been reported from different parts of Ethiopia, however, the serostatus and risk factors of this disease in small ruminants is not well documented in southwestern parts of the country. This study was conducted from October 2016 to October 2017 to investigate the seroprevalence and associated risk factors of brucellosis as well as its association with abortion in sheep and goats in selected districts of Jimma zone. A total of 804 small ruminants (402 sheep and 402 goats) were randomly selected and blood samples were collected for serological tests. The presence of antibody to Brucella was screened by Rose Bengal Plate Test and confirmed using the complement fixation test. Seroprevalence of 4.2% in sheep and 5.2% in goats was recorded in this study. An overall seroprevalence of 4.7% was recorded in small ruminants in the study areas. Brucella seropositivity was observed more frequently among sheep and goats with a history of abortion (6.7%) than animals that have no history of abortion (3.7%), however, the difference noted was not statistically significant. Older age (OR 3.9, CI = 1.43-9.94), pregnancy (OR 2.6, CI = 1.19-5.72), late term gestation (OR 2.4, CI = 1.54-3.78), mixed flock (OR 2.8, CI = 1.33-5.89) and larger flock size (OR 2.7, CI = 1.08-6.95) were noted to have more number of reactors. Hence, it is important to consider brucellosis as one of the diseases that needs attention and further study should be conducted to identify the circulating Brucella species and other causes of abortion in sheep and goats. Besides, this finding warrants the need for further investigation on its public health impact in the region. Keywords: Brucellosis; Epidemiology; Sheep; Goat; Jimma Zone

“…In 1968, Jamaica reported an unknown number of cases of BoHV‐1 (OIE‐HANDISTATUS II, 2005). A study carried out during 2018 in Trinidad and Tobago detected BoHV‐1 antigens in 23% of bulk milk samples from dairy cattle (Morris et al., 2018). A similar ELISA‐based study in Grenada reported a lower prevalence of BoHV‐1 in cattle (3.8%) and in sheep (0.42%) (Tiwari et al., 2016b).…”

Viruses pose a major threat to animal health worldwide, causing significant mortalities and morbidities in livestock, companion animals and wildlife, with adverse implications on human health, livelihoods, food safety and security, regional/national economies and biodiversity. The Greater and Lesser Antilles consist of a cluster of islands between the North and South Americas and is habitat to a wide variety of animal species. This review is the first to put together decades of information on different viruses circulating in companion animals, livestock and wildlife from the Caribbean islands of Greater and Lesser Antilles. Although animal viral diseases have been documented in the Caribbean region since the 1940s, we found that studies on different animal viruses are limited, inconsistent and scattered. Furthermore, a significant number of the reports were based on serological assays, yielding preliminary data. The available information was assessed to identify knowledge gaps and limitations, and accordingly, recommendations were made, with the overall goal to improve animal health and production, and combat zoonoses in the region.

“…This needs further investigations. Furthermore, precise role of the isolated virus (BoHV5/India/2018/Bhilwara), other infectious agents (bacterial/parasitic) or their coinfections [39][40][41][42][43] needs to be examined.…”

Isolation and characterization of bovine herpes virus 5 (BoHV5) from cattle in India

Bovine herpesvirus 1 (BoHV1) and 5 (BoHV5) are genetically and antigenically related alphaherpesviruses. Infection with one virus induces protective immunity against the other. However, disease associated with BoHV1 and BoHV5 varies significantly; whereas BoHV1 infection is usually associated with rhinotracheitis and abortion, BoHV5 causes encephalitis in cattle. BoHV5 outbreaks are sporadic and mainly restricted to the South American countries. We report BoHV5 infection for the first time from aborted cattle in India. Based on the characteristic cytopathic effects in MDBK cells, amplification of the viral genome by PCR, differential PCR for BoHV1/BoHV5, nucleotide sequencing and restriction endonuclease patterns, identity of the virus was confirmed as BoHV5 subtype A. Serum samples from the aborted cattle strongly neutralized both BoHV1 and BoHV5 suggesting an active viral infection in the herd. Upon UL27, UL44 and UL54 gene-based sequence and phylogenetic analysis, the isolated virus clustered with BoHV5 strains and showed highest similarity with the Brazilian BoHV5 strains.
